KDP Book Resizer by Etemora
Resize your book PDF to KDP trim sizes in your browser
Rescale a finished book interior PDF to a KDP paperback or hardcover trim size without reflowing the text, so page count and line breaks stay the same. Add 0.125 in bleed, match margins to KDP minimums, then run a preflight that checks page size, page count, text, image resolution and blank pages. Runs in your browser: the PDF is never uploaded. Free, no sign-up. Interiors only, up to 100 MB.
Hi, I'm Zaid. I design and format books for KDP, and the same problem keeps coming back: someone has a finished interior PDF in one trim size and needs it in another, or KDP rejects it with "trim size does not match". Rebuilding the whole layout for that is a lot of work.
So I built a free KDP Book Resizer:
- Rescales a finished interior PDF to a KDP paperback or hardcover trim size without reflowing the text, so page count and line breaks stay the same
- Optional 0.125 in bleed and a margin check against KDP minimums
- A preflight that checks page size, page count, text, image resolution and blank pages
- Runs in your browser: the PDF is never uploaded, no sign-up
Limits, honestly: it scales pages, it doesn't re-typeset them, so a big size jump can make text smaller or larger than ideal. It's for interiors only, not covers, and the preflight is a practical guide, not an official KDP approval.
I'd love feedback: which trim sizes or checks should I add next?
