7 Best PDF Converter Software in 2026: Fast and Secure Options

The best PDF converter software is accurate, secure, and doesn’t add unnecessary complexity. These tools allow you to convert files to and from PDF, and hands-on tests of seven popular options found that layout and structure held up far better than fonts did.

If you often need to turn PDFs into Word, Excel, PowerPoint, or image files, and vice versa, for editing, sharing, and archiving, our guide has you covered. We ran the same PDF-to-Word, PDF-to-Excel, and PDF-to-PowerPoint conversions through seven converters, and here’s how they held up.

Key Takeaways

• The best PDF converter software for you depends on the file types you convert most, how often you convert them, and whether accuracy, price, or batch processing matters most.
• Adobe Acrobat and PDF24 tied for the top score; Adobe on overall accuracy and reliability, PDF24 for matching that score with a completely free tool.
• Nearly every tool altered fonts during conversion; PDF24 was the only one that kept fonts intact by default, though it lost some table borders and field underlines in the process.
• Format support, file-size limits, and batch conversion vary widely, from pdf.net's single-file free tier to PDF24's free batch of 20-plus files at once.

What Makes the Best PDF Converter?

There are several features that make the best PDF converter, such as:

• Support for multiple file formats. This is especially important for small businesses as they usually manage different file types. Contracts may be created in Word, invoices in Excel, and presentations in PowerPoint, but these need to be PDFs for standardized sharing, storing, and archiving. Without broad support, you will have to juggle several converters, which fragments your workflows.
• High conversion accuracy. A converted file that loses or shifts details, causing readability issues, defeats the purpose of using a converter in the first place. If you still need to spend time fixing the file manually, you might as well recreate it from scratch. Therefore, a reliable PDF converter software should produce results you can use immediately.
• An easy-to-use interface. You can jump right into converting documents if the software has an intuitive interface. In larger teams, this means you won't have to spend significant time or resources on training and integrating it into existing workflows. Instead, those efforts can be redirected toward higher-value work.
• Strong security and privacy protections. Small businesses often handle sensitive documents such as contracts, NDAs, financial records, and tax forms. A PDF converter software with strong security features and clear privacy practices helps protect this data during processing, reducing the risk of leaks and compliance issues.

7 Best PDF Converter Software Ranked by Test Results

Everybody needs PDF converter software that is easy to adopt, supports everyday tasks, and fits within a reasonable budget. The seven tools tested were scored across five categories (file-size limit, format breadth, batch-conversion support, conversion accuracy and reliability, and accessibility) and here's how they compare:

Disclaimer: All seven tools below were tested by running the same three source files. Testing covered three round-trip conversions per tool: PDF to Word and back, PDF to Excel and back, and PDF to PowerPoint and back. Also, each tool's supported file formats, file-size limits, and batch-conversion capability were checked.

#1. Adobe Acrobat

Adobe Acrobat is a well-established platform, though converting files requires a paid plan. It supports 14 file formats on desktop and eight on the web, including less common ones like TIFF, RTF, EPS, and PostScript.

In testing, Adobe Acrobat accepted files as large as 750MB with no hard limit, though it occasionally rejected complex files under 200MB with a “file is either too large or too complex to export” error. Both the web and desktop (Acrobat Pro) versions support batch conversion.

Overall, Adobe Acrobat kept layouts, tables, and logos intact more consistently than any other tool tested, handled the largest files, and supported the most formats, at the cost of a premium price and a required sign-in.

#2. PDF24

PDF24 is a free PDF converter, and every feature tested, including batch conversion, was available without an account or a subscription. It supports 21 different file formats, including PDF/A, Word, PowerPoint, Excel, Publisher, TIFF, ODT, RTF, EPUB, and even Markdown files.

The test found no file-size limit, and batch conversion processed 20 or more files at once with no account required. Also, Word conversions stood out since PDF24 was the only tool tested to preserve fonts and layout in its default (Auto) mode, though table borders and field underlines dropped out unless the Fixed mode was selected instead.

On the other hand, Excel and PowerPoint conversions were less consistent. PDF-to-Excel conversion extracted the data accurately, but the visual layout was off and introduced a stray colored block that wasn't in the original. PDF-to-PowerPoint testing found four embedded fonts that failed to install, turning some characters into boxed symbols and dropping the presentation's hyperlinks.

#3. Smallpdf

Smallpdf is an online PDF converter that works without sign-ups. In testing, it accepted files up to 200MB and required a paid plan for batch conversion. The free tier processes one file at a time, limits you to 2 downloads per day, and doesn't offer OCR for image processing. You will need to purchase a plan to access this feature, along with unlimited document downloads. To do so, you can choose between three pricing plans:

• Pro ($12 per month)
• Team ($10 per month per seat)
• Business (custom pricing)

As for security, the tool applies TLS encryption during transfer and automatically deletes your files after one hour.

#4. iLovePDF

iLovePDF's free web app requires no account and supports seven different file formats, including PDF/A, Word, PowerPoint, Excel, and HTML. Testing found no limit on the number of downloads, though files are capped at 15MB on the free tier; a paid Premium plan raises that ceiling to 4GB per task and unlocks batch conversion for up to 10 files.

iLovePDF's PDF-to-PowerPoint conversion was the standout result in testing: layout, fonts, images, tables, and hyperlinks all came through looking essentially identical to the original.

On the other hand, PDF-to-Word conversion showed the same issue found in Smallpdf: layout held up well, but the font was not preserved, and iLovePDF misread some characters (“T” became “fi”). PDF-to-Excel testing preserved the invoice's structure and colors reasonably well, though the logo shifted position and spacing tightened around the table; the desktop app's Excel-to-PDF conversion, by contrast, preserved everything from the original file.

#5. pdf.net

pdf.net is an online PDF converter with an incredibly intuitive interface. You can use it to convert between PDF and 10 other file types, including DOCX, PPTX, XLS, JPG, PNG, HEIC, EPUB, Markdown, CSV, and TXT. It handles files up to 500MB which is one of the more generous limits among the tools tested.

Even though it lacks batch conversion, it's still the most affordable, browser-based option here. It also comes with built-in sharing tools once your document is converted, which makes it one of the best Adobe Acrobat alternatives, especially for small businesses.

It comes with three accessible pricing plans:

• $0.95 for a 14-day limited access
• $1.95 for a 14-day full access
• $24.95 per month (billed annually)

Keep in mind that converting a file is free, but you'll need to pay before you can download the result.

#6. pdfFiller

pdfFiller is another online PDF editor, but with only five supported formats (PDF, Word, Excel, PowerPoint, and image), the narrowest range of any tool on the list here. Also, conversion accuracy varied sharply by format.

PDF-to-PowerPoint conversions came out nearly identical to the original, with fonts, images, layout, and hyperlinks all intact. PDF-to-Word conversions were shakier: currency symbols switched from $ to €, and "of" was misread as "ofi" in two spots. PDF-to-Excel-to-PDF round-tripping fared worst of all, splitting the test invoice across six separate sheets before re-exporting it as a messy four-page PDF.

There are three pricing plans:

• Basic ($8 per month)
• Plus ($12 per month)
• Premium ($15 per month)

Each plan offers different functionalities; however, a noteworthy aspect of this platform is that it gives you the option to preview pages and remove unnecessary ones before converting. With this functionality, you don't need to look for a different tool to split PDFs and then merge them. Also, pdfFiller supports batch conversion, but it caps file size of PDFs at 100MB, and other file types at 25MB.

#7. Foxit PDF

Foxit PDF supports 12 file formats, including PDF, Word, JPG, Excel, PNG, PPT, TXT, TIFF, HTML, BMP, RTF, and GIF. It is possible to upload documents from your device's storage or from Google Drive, OneDrive, or Dropbox. The free web app caps files at 15MB, so you'll need the desktop version for anything larger.

If you work with many PDFs every day, note that batch processing is only available in Foxit's desktop app; the web tool converts one file at a time. Foxit PDF converter finished last mainly because of its small free-tier file limit and its Excel-to-PDF reliability problems.

The Most Popular PDF Conversions

The most popular PDF conversions are:

• PDF to Word (DOC or DOCX)
• PDF to JPG or JPEG
• PDF to Excel (XLS or XLSX)
• PDF to PNG
• PDF to PowerPoint (PPT or PPTX)

Word, Excel, and PowerPoint are the most commonly used tools for creating, editing, and sharing documents. Converting PDFs back into these formats allows you to reuse content without wasting time recreating files.

Image conversions are also widely used for quick sharing and compatibility. They make it easier to send receipts, forms, or visual pages through various channels (e.g., email, messaging apps, or cloud platforms) when editability is not needed.

You might also find the following conversion options in full-fledged PDF tools:

• PDF to ePUB
• PDF to TXT
• PDF to GIF
• PDF to TIF
• PDF to TIFF
• PDF to RTF
• PDF to BMP

How to Pick the Best PDF Converter Software

Follow these four steps to pick the best PDF converter software for yourself or your business:

1. Note down the types of files that you handle regularly, such as Word, Excel, PowerPoint, JPG, and PNG. To avoid accidentally leaving any out, you should think through your typical workflows; who do you typically send documents to and receive documents from? Then, check if the PDF converter you are considering supports those file types in both directions (to and from PDF).
2. Consider the number of conversions you typically handle and the devices you use. This can help you determine what additional features your PDF converter should offer. For example, you may need a fully browser-based tool for mobile compatibility or a converter that supports batch processing for higher volumes.
3. Run a few of your actual files through the PDF converter software. You should check for missing text, broken tables, shifted layouts, and font changes. If it needs cleanup every round, it won't save you time, and you should go with a different option. Additionally, assess whether it is easy for the whole team to use. Are there easy upload options? How many steps are required before you can download the converted document?
4. Decide whether a free or paid PDF converter is the better fit. Free tools work well for quick, one-time conversions, but they tend to be restrictive for regular use. You may face daily download or file size limits, and you often will not have access to features like batch processing or OCR. Weigh these pros and cons carefully to make the right choice.

Final Thoughts

Each of the tools we tested handled some conversions better than others, however, before deciding on the best PDF conversion software, consider the file types you work with most, how often you need to convert them, and which features your workflows require. Once you have a reliable tool, you can save time switching between file formats.

If font accuracy matters for your documents, legal contracts or branded templates, for example, plan to manually review and adjust fonts after any PDF conversion, since none of the tools we tested preserved them perfectly.

Best PDF Converter Software FAQs

#1. Are online PDF converters safe?

Online PDF converters can be safe if you choose reputable tools that use secure file handling and have clear privacy policies. Look for converters with HTTPS connections, TLS encryption, and don't store documents longer than necessary.

#2. Is there a difference between online and desktop PDF converters?

Yes, there is a difference between the two. Online PDF converters eliminate installation hassles, storage requirements, and manual updates. While desktop PDF converters demand disk space and IT permissions, browser-based ones work instantly across any device — your work laptop, home PC, or tablet.

#3. Can I convert a PDF to Word without losing formatting?

Yes, but expect some formatting loss. In our test, layout and tables usually transferred well, but fonts changed in each tool. For best results, check the converted file for font and field changes afterward.

#4. Do online PDF converters work on mobile?

All the online PDF converters listed above work on mobile. None require a desktop install, so you can convert files from a phone or tablet browser as long as you have a reliable Internet connection.

#5. Can I convert scanned PDFs?

Yes, you can convert scanned PDFs by applying OCR. This extracts text from scanned pages and makes the documents editable.

#6. Do PDF converters preserve original fonts?

No, not reliably. In our test of seven popular PDF converters, almost all of them changed or failed to preserve the original font during PDF-to-Word conversion. If font accuracy matters, review and manually reset fonts after converting.
