Send to Kindle PDF Size Limit: How Big Can Your File Be?

The maximum file size for sending a PDF to your Kindle using Send to Kindle is 200 MB per file. If your PDF is larger than that, Send to Kindle will reject it and Amazon will notify you by email. Here’s how to check your file size and what you can do if your PDF is too big.

What is the size limit for PDF files with Send to Kindle?

Amazon sets a 200 MB limit per file when sending documents to Kindle with Send to Kindle, whether you use the web version, the desktop app, the mobile app, or email to your @kindle.com address. This applies to PDFs, EPUB, DOC, DOCX, TXT, RTF, HTML, and image files. If your file is over 200 MB, Send to Kindle won’t accept it.

How do I check if my PDF is over the limit?

Before sending, check your PDF’s file size. If it’s over 200 MB, Send to Kindle won’t work. If it’s under the limit, you can send it as usual.

What can I do if my PDF is too large?

• Convert your PDF to a compatible format: You can use Legible to convert your PDF to EPUB. Legible rebuilds your PDF as a Kindle-style book with flowing text, keeps headings and lists, and creates a table of contents even if your PDF doesn’t have one. You can send the EPUB with Send to Kindle or transfer the AZW3 file by cable.
• Transfer the file by cable: If your PDF or the converted book is still over the Send to Kindle limit, you can copy it directly to your Kindle with a USB cable. For details, see How to Transfer Files to Kindle by Cable or Internet.
• Send another supported format: Send to Kindle accepts EPUB, DOC, DOCX, TXT, RTF, HTML, and images, as long as they don’t exceed 200 MB.

What happens if I try to send a file that’s too big?

If you try to send a file over 200 MB, Send to Kindle will automatically reject it and you’ll get an email letting you know it couldn’t be delivered. In that case, try one of the alternatives above.
