But after I import my computer’s PDF ebooks to my kinlde, I found it not very comfortable to read PDF in Kindle, one of my friends said that it is a good choice for us to convert pdf to mobi for kindle? Really? Could you give me some suggestions for kindle reading? Should I have to convert my pdf to mobi for kindle reading? If, so , how can I do then? Yours every answers is welcome. Thanks very much!

Short answer: you do not always have to convert PDFs for a pleasant Kindle reading experience, but converting is usually the best choice for long, text‑only books. PDFs are fixed‑layout (page images), so font size, line breaks and reflow won’t behave like a normal ebook; that’s why found reading PDFs uncomfortable on a Kindle Fire. For simple novels and prose, convert to a reflowable format; for heavily formatted textbooks, magazines, or scanned pages, keep the PDF or OCR it first. (manualzilla.com)

If you decide to convert on macOS: use calibre (free, cross‑platform) to convert to AZW3 (KF8) for best native Kindle results, or to EPUB if you prefer to use Amazon’s Send‑to‑Kindle conversion. In calibre: Add books → select a book → Convert books → choose AZW3 (or EPUB), pick the Kindle output profile, then Send to device or copy the output into the Kindle’s Documents folder. Calibre documents both conversion options and the traps (PDF input often needs extra work). (manual.calibre-ebook.com)

Important format note: Amazon stopped relying on MOBI for the cloud Send‑to‑Kindle workflow and moved toward EPUB/AZW3-style processing; MOBI is no longer the recommended path for wirelessly adding personal books. If you email a PDF to your Kindle address with the subject Convert, Amazon will attempt to convert it to Kindle format for reflowable reading — useful for quick fixes but not perfect for complex layout. For scanned PDFs run OCR first (Tesseract, Adobe, ABBYY, etc.) before converting. (fivefilters.org)

Troubleshooting tips pulled from this thread and practical use:

  1. Try one chapter first — conversion quality varies.
  2. If text looks broken or missing, the PDF is probably scanned or uses embedded fonts → OCR and retry.
  3. If a converted file shows up as a “Document” instead of a book (as @kevin-johnson noted), reconvert using AZW3 or reprocess metadata in calibre to remove the personal‑doc tag.
  4. Be aware Amazon’s web changes (for example, removal of some download/transfer features) affect how you move files between devices; keep local backups of originals. (theverge.com)

Quick recommendation: for novels — convert to AZW3 with calibre. For scanned/complex PDFs — OCR first or read as PDF on a tablet. If convenience matters (cloud syncing, notes), try Send‑to‑Kindle with subject “Convert” for a fast test before doing manual conversions.

Yes from my point of view .mobi is batter than .pdf file for kindle. You can convert your .pdf file to .mobi online or you can download software for the conversion. You can use this site for online conversion.

http://www.convertfiles.com/convert/document/PDF-to-MOBI.html

but sometime .mobi is look like just documents instead of book.The issue that is causing the device to register your .mobi file as a document rather than a book is that there was a personal doc tag (PDOC) placed in the .mobi file during conversion. This tag needs to be removed by reconverting the book without the problematic PDOC.

To solve this problem visit this website it has article to solve this problem and also software available that helps you.

Yeah, sometime, Kindle doesn’t support PDF well, you need to change the PDF into kindle’s .mobi. There are two free ways to change PDF to mobi for kindle reading, many Kindle users convert PDF to MOBI format using the free program Calibre, and anther way is Zamzar.com, which is a cool online file conversion tool that can convert a variety of file formats from one format to another, but you just need to upload the file, select the output format, enter your email and click convert, but it is not a safe way, because you have to upload your files to the internet, so chose the way depending to your needs.
