An online PDF password remover is a browser-based tool that strips a known password from a protected file, so you can open, edit, or share the file without re-entering that password every time. It helps whenever you have the correct password, but retyping it every time you open the file, or sending a locked PDF to someone else, slows you down.
To find the best PDF password remover online, we ran the same password-protected PDF through eight popular tools, including PDFgear, PDF24, iLovePDF, pdf.net, PDF2Go, PDF Candy, Smallpdf, and Sejda, checking what each one lets you do. Here’s what we’ve found.
Key Takeaways
- PDFgear and PDF24 unlocked our test file for free, with no account and no file-size limit we could find.
- pdf.net accepts more input formats (including HEIC and Markdown) and lets you keep editing, signing, and re-protecting the file afterward without switching tools.
- Speed varied by about a second between tools: iLovePDF, PDFgear, PDF2Go, and PDF Candy unlocked files in 1-2 seconds; pdf.net, Smallpdf, and PDF24 took 2-3 seconds.
- Sejda failed to unlock either of our test files, even though it otherwise tested well for editing and form tools elsewhere in our review.
- A password remover software only unlocks the file itself; if a PDF also blocks printing or copying, you'll need to remove PDF restrictions separately, which we cover below.
How We Tested These PDF Online Password Removers
We tested these PDF online password removers by uploading the same password-protected PDF to all eight tools, entering the correct password, and recording what happened next. For every tool, we tracked:
- Whether the unlock succeeded or failed
- How long the process took, from upload to a downloadable file
- Whether an account was required, and what free-use limits applied
- The maximum file size allowed on the free tier
- Whether the unlocked PDF kept its original formatting and quality
We used one standard test PDF file across every tool and repeated the process where a tool offered more than one unlocking method. All of the tools we tested require you to enter the existing password before they unlock the PDF file.
That's because PDF password protection typically relies on strong ciphers like the Advanced Encryption Standard.

In our test for the best PDF password remover online, we weighed in password-removal alongside how well each tool supports the rest of your document workflow. Here's how all eight compared, followed by a closer look at each one:
Tool | Did It Work? | Unlock Speed | Free Access | File Limit |
|---|---|---|---|---|
PDFgear | Yes | ~1-2 sec | Free, no account, no limits found | None stated |
PDF24 | Yes | ~2-3 sec | Free, no account, no limit found | None stated |
iLovePDF | Yes | ~1-2 sec | No account, no limit on unlocks | 100 MB |
pdf.net | Yes | ~2-3 sec | Payment required before download | 500 MB |
PDF2Go | Yes | ~1-2 sec | 8 free credits, no account needed | 100 MB free |
PDF Candy | Yes | ~1-2 sec | 3 downloads/hour, no account | 50 MB free |
Smallpdf | Yes | ~2-3 sec | 2 free downloads, no account | 200 MB free |
Sejda | No | N/A | Could not complete test | N/A |
#1. PDFgear
PDFgear removed the password in about 1-2 seconds; the fastest tier in our test, tied with three other tools. This online tool to remove a password from PDF is free, didn't ask us to create an account, and we didn't hit a file-size, page-count, or usage limit anywhere in testing. The unlocked file kept the same formatting and quality as the original.
The online unlocker itself is single-purpose, but in separate testing of PDFgear's desktop app, it let us edit PDF text and add images without hitting a paywall; a feature iLovePDF and Smallpdf both lock behind a paid plan.

#2. PDF24
PDF24 unlocked our test PDF in about 2-3 seconds. Like PDFgear, it didn't require an account, and we found no usage limit or file-size cap during testing. The output file preserved the original formatting.
Beyond password removal, PDF24's Windows desktop app works fully offline and bundles tools for merging, splitting, compressing, OCR, and signing.

#3. iLovePDF
iLovePDF removed the password in roughly 1-2 seconds, making it one of the fastest PDF unlockers we tested. No account was required, and we didn't encounter a limit on the number of unlocks or downloads. The free plan's 100 MB file-size limit is the main restriction we found.
Outside of password removal, iLovePDF offers the broadest platform coverage in this roundup, including web, Windows, macOS, and mobile apps.

#4. pdf.net
pdf.net's PDF password remover unlocked the file in about 2-3 seconds, on par with the mid-pack speed we saw from Smallpdf and PDF24. The fact it ranked in the top half of this list is because of what else you can do once you upload and unlock the document.
The platform accepts different file formats (PDF, Word, Excel, PowerPoint, PNG, JPG, HEIC, HEIF, and even Markdown files) and lets you keep working on a document afterward. This includes editing text, reordering pages, adding page numbers, signing, and more — without switching tools.
Pros | Cons |

#5. PDF2Go
PDF2Go unlocked the PDF in about 1-2 seconds. The platform uses a credit system: one credit for every 30 seconds of processing. We started with a balance of eight free credits and weren't asked to create an account while credits remained.
Even though the free tier caps files at 100 MB, it’s worth for occasional use, when you're not unlocking more than a couple of files at once.
Pros | Cons |

#6. PDF Candy
PDF Candy unlocked the file in about 1-2 seconds once we entered the correct password. Also, it offers an automatic unlock option for people who don't know their password, but that feature failed on our test file.
No account was required for our initial tests, though unregistered users are capped at three downloads per hour. Therefore, if you’re looking for more than a quick, single unlock under 50 MB, this tool isn’t the right choice.
#7. Smallpdf
Smallpdf removed the password in about 2-3 seconds. We completed two downloads without creating an account; a third attempt would have required a paid plan.
As for other tools, like editing PDF text and reordering pages both required a Pro subscription, and the free plan also capped us at two tasks per 12 hours on tools like merging.
Pros | Cons |
|---|---|
|
|

#8. Sejda
Sejda
Sejda failed to unlock the PDF file online. The tool didn't recognize the password, even though the identical password and file worked on every other tool we tested. Because we couldn't get past the password step, we have no data on Sejda's download speed or output quality for this specific task.
That's a notable miss, since Sejda otherwise tested well in our broader review; it supports editing PDF text, forms, OCR, and Bates numbering, runs natively on Windows, macOS, and Linux, and its interface is available in more than 30 languages.

How to Choose the Right PDF Password Remover
Choosing the right PDF password remover implies matching three things to your situation: how large PDFs are, how often you need to unlock them, and whether you're comfortable creating an account or paying upfront.
That said, consider the following before you opt for an online PDF password remover:
- File size. If your PDF is under 50 MB, almost any tool works. Larger files almost always require some kind of subscription.
- Frequency. For a one-off unlock, a free tool with a low usage cap is fine. If you need a PDF unlocker on a regular basis, unlimited free access saves you from hitting a wall.
- Type of restriction. A password remover only handles password-protected files. If your PDF instead blocks printing, copying, or editing without a password, you'll need to remove PDF restrictions separately, since that's a different kind of lock.
- What happens afterward. If you also need to edit a PDF once it's unlocked, or plan to password-protect a PDF again before sending it elsewhere, a bundled tool saves you from switching platforms mid-task.
Is It Safe to Remove a PDF Password Online?
Removing a PDF password online is safe as long as the tool encrypts the upload (HTTPS in the address bar) and deletes your file after processing. However, you should still avoid uploading highly sensitive documents to a site you don't recognize.
Therefore, before you trust any online tool to remove a password from a PDF, it's worth spending time on a few practical checks before you upload anything:
- Confirm the page uses HTTPS, which encrypts the file in transit. The U.S. Customs and Border Protection agency's own guidance on password-protecting PDF documents is a useful reference for how government agencies handle document security on their end.
- Check whether the tool states a file-retention policy. Therefore, look for clear encryption and deletion practices before uploading sensitive files to any third-party service.
- Be cautious of unsolicited links claiming to "unlock" a PDF sent to you by email. The FTC's guide to recognizing phishing scams notes that fake attachments and lookalike tools are a common way attackers steal credentials.
- If you're regularly sending documents by email, removing the password only for that one exchange, rather than permanently, keeps the file protected everywhere else it's stored.
Final Thoughts
Our testing found that the free tools, like PDFgear and PDF24, handled password removal just as well as the paid options, while Sejda's failure was the biggest surprise in the roundup. If you only need to unlock a PDF you already have the password for, start there before paying for anything.
For everything else you might need to do with that file afterward, from protecting it again to editing or converting it, look for a PDF editor with more features.
Best PDF Password Remover Online FAQs
#1. Which PDF password remover is completely free?
PDFgear and PDF24 were completely free in our testing, with no account, payment, or file-size limit standing between you and your unlocked file. Both handled our test PDF in under three seconds, making either the best online PDF password remover for everyday, no-cost use.
#2. Can I unlock a PDF without a password?
You can only unlock a PDF without a password if a tool offers a dedicated "unknown password" feature, and even then it's not guaranteed. PDF Candy offers this option, but it failed on both of our test files, so most password-protected PDFs still need the correct password before any of these tools will touch them.
#3. Is it safe to use an online tool to remove a password from a PDF?
Using an online tool to remove a password from a PDF is safe if the site uses HTTPS and deletes files after processing. Avoid uploading highly sensitive documents, like financial or legal records, to any tool you haven't verified first.
#4. How do I open a locked PDF if I forgot my password?
You open a locked PDF you've forgotten the password for by recovering the original password first, not by using a password remover; none of the eight tools we tested can guess or crack one. Check a password manager or old emails for the original, or contact whoever created the file.
#5. What if my password-protected file is a word document, not a PDF?
A PDF password remover won't work on a Word file, since the two formats protect content differently. If you're locked out of a .docx instead, check our guide on how to unlock a Word document.
#6. Can I remove a password from a PDF without Acrobat?
Yes, all of the eight tools we tested act as Adobe Acrobat alternatives for unlocking files online since Adobe doesn't support unlocking/removing passwords on the web app . PDFgear, PDF24, iLovePDF, pdf.net, PDF2Go, PDF Candy, and Smallpdf all removed our test PDF's password entirely in the browser.
#7. Can I permanently unlock a PDF?
Yes, once a password remover strips the protection, the unlocked PDF stays that way permanently; none of the tools we tested re-lock the file or expire the change.
