4 Benefits of Adding PDFs to Your Kindle Library
The benefits of adding PDFs to your Kindle library include adaptable reading modes and time and location flexibility, among others.
Let’s examine these benefits more closely:
#1. Portability & Battery Life
You can read PDF files on Kindle after adding them to your library anytime, as this device is portable. Kindle is also appropriately sized to fit most bags or other items you can use to carry it.
The Kindle screen allows for adjustable brightness, with the option to make it very bright. Still, this does not mean this device has a weak battery life. In contrast, you can use a Kindle for hours or even days without charging.
#2. Reading Adaptability
Among various features, you can side-load PDFs on Kindle, making the margins smaller and the text larger, which is good for readability. Also, you can switch to reading mode. This mode reduces the blue light emission, which is known to have a substantial effect on the eyes and the human brain, primarily affecting sleep patterns.
Kindle boasts useful contrast options as well, meaning that you can make text lighter or darker, depending on the background, to make it more readable. Similarly, adapting page refresh settings can make your scrolling smoother. Using the same settings, you can turn on page animation to prevent monitor ghosting or having leftover text after you turn a page.
Finally, you can read PDFs on Kindle in both portrait and landscape modes, which makes the reading process better by properly rendering the page contents on your screen for a clearer and larger view.
#3. PDF Modification
Kindle allows you to modify PDFs by highlighting text or adding comments and sticky notes. This built-in option requires skills similar to those you would use to highlight PDFs with designated tools.
In addition, annotating and highlighting your files can help you emphasize their important parts. This is helpful for the proofing process, studying, performing analyses, or summarizing your documents.
#4. Format Diversity, PDF Organization, & Sharing
The format diversity enables you to use different documents and read non-Kindle books on Kindle. Specifically, Kindle supports formats such as PDF, Word, JPEG, GIF, PNG, and BMP. Speaking of PDFs, you can use Kindle for any PDF document regardless of whether it is compressed, converted, or modified in any other way.
Furthermore, you can organize PDFs within your Kindle library using the Collections feature, allowing you to sort files according to their genre, type, or similar category.
Lastly, you can share your PDFs after adding them to your library. While adding PDFs to Kindle may take a while depending on your chosen method, sending them from your device to another is much faster (you can do it in just a few clicks).
How to Email a PDF to a Kindle in a Few Clicks
To email a PDF to a Kindle in a few clicks, find your Kindle email address, add a new approved address, and send the PDF file.
Let’s further examine the steps to send a PDF to Kindle via email:
#1. Check Your Kindle Email Address
Each Kindle account has its own email address to which you should send files. Here is how to find it:
- Go to the Amazon website, sign in to your account, and select Accounts and Lists.
- Choose Your Devices and select Manage Devices.
- Click on the Devices button and open the Device Summary page.
- Locate and copy the email address shown on this page.
#2. Get Your Email Approved
You will not be able to send emails to your official Kindle address unless you add a personal email address and have it approved. Here’s how to do so:
- Sign in to your account and click Accounts and Lists.
- Select Your Devices, choose Manage Devices, and click the Preferences button.
- Choose Personal Document Settings and click the Approved Personal Document E-mail List.
- Choose the Add a New Approved e-mail address button, enter your email address, and click Add address to finalize this process.
#3. Send Your Document
The last step is to send your PDF to Kindle. Open your private email address service, enter your Kindle email address as a recipient, and attach the file you want to send.
You can leave the subject field empty or type ‘Convert’ if you wish Kindle to convert your document automatically to its custom format. Afterward, you will find your file in the Kindle library.
How to Upload a PDF to a Kindle Via USB
To upload a PDF to a Kindle via USB, connect it to a computer device, find the Kindle destination folder, and then copy and paste your document.
Here’s a step-by-step guide on transferring files to Kindle via USB:
- Plug a Kindle into your computer.
- Find the target ‘Download’ folder (you can use Finder on Mac and the Search feature on Windows).
- Copy the file you want to transfer and paste it into the Download folder.
- Select the Kindle device on Mac, right-click it, and choose Eject Kindle, or right-click the Kindle drive in the bottom right corner on Windows and select Eject Amazon Kindle to complete this process.
How to Upload a PDF to a Kindle Via the Desktop App
To upload a PDF to a Kindle via the desktop app, you should follow this simple guide:
- Download and install the Amazon desktop app.
- Sign in to your Amazon account.
- Open the program and choose Send to Kindle.
- Drag and drop your PDF and wait for automatic upload.
Compress Large PDF Files with PDF.net for Better Performance
To make reading PDFs on Kindle easier, you can compress your files before uploading them. The lower the file size, the quicker the upload process will be. In addition, it is vital to choose the right tool for this, as not every software boasts high functionality.
For instance, some cheap tools may corrupt your file, rendering it useless. Plus, the same software can diminish the quality of your document, making it barely readable or completely unreadable.
As a result, you might need to undergo a tedious corrupt data recovery process. Likewise, you can attempt to enhance the document's color and contrast for improved accessibility. However, these methods are not always effective, as the file damage can be too extensive.
To avoid this and make the most out of your Kindle experience, you can compress PDFs without losing quality with PDF.net. Our tool offers lossless compression, which is a high-end file-shrinking process where all the important PDF elements remain intact, hence preserving quality.
Moreover, you can easily find your way on our user-friendly platform, allowing you to compress files without being tech-savvy.
Why File Size Matters for Smooth Kindle Reading
Size is important for smooth Kindle reading because this device may not handle large PDFs well. Specifically, large files may take a lot of time to upload or transfer, and Kindle may have trouble loading them once you want to open them. Plus, even if Kindle opens larger PDFs, you may have trouble scrolling through the document, making reading difficult.
Another reason why size matters for reading is the Kindle’s limited storage, which you can quickly fill up with large files, requiring you to delete existing documents to free up space.
To prevent such situations, you can resize your PDFs to upload numerous documents and read them without constantly swapping old files for new ones.
PDF Compression That Preserves Quality
Shrinking PDFs is easy with our high-end compression tool. To streamline this process, you can do the following:
- Visit PDF.net, hover over the More Tools menu, and click Compress.
- Drag and drop your document into the box labeled Drop files here to compress or click Choose file to upload it manually.
- Choose between the Smallest file size, Balanced, and Better quality compression type, and click Compress and download to shrink your file and save it to your storage.
Beyond Compression: Essential PDF.net Tools for Kindle Readers
Going beyond compression, you can use various other tools on our website to facilitate reading PDFs on Kindle or modify your document for any other purpose.
Here are the most popular options:
- PDF converter. As Kindle cannot open EPUB and similar formats like Excel, you can use our Excel to PDF converter to transform your file to a usable format. In addition, you can switch between supported formats (e.g., PNG to PDF) based on your preferences.
- Split and merge. If the PDF document you want to send to Kindle is too large, you can split it with our software and upload separate files, which you can easily merge afterward if you lose the original file.
- Chat with PDF. You can analyze your PDFs and enhance your reading experience on Kindle by asking our AI tool to provide details about them. This software also allows you to summarize files in different formats (short or long summaries, bullets, tables, etc.).
Final Thoughts
Reading PDFs on Kindle is possible after sending or uploading files to this device via USB, email, or through a desktop app.
Each method has its pros and cons, but the Amazon desktop app offers the simplest and fastest way to transfer PDFs to Kindle. However, you can streamline the other methods with the assistance of PDF.net tools, which can, among many different opportunities, help you compress or split your documents for easier upload.
