How to Fix Amazon KDP Bleed Issues
Many authors search for how to fix an Amazon KDP “bleeding” error. In print, the standard term is bleed: extra artwork past the final trim so cutters do not leave white hairlines. When bleed is wrong, Kindle Direct Publishing can reject your paperback interior PDF right after upload.
For Kindle Direct Publishing, your interior must match the trim size you chose for the title and the mechanical rules Amazon publishes for that format. Bleed problems usually mean full-bleed backgrounds or images stop at the trim line instead of extending through the bleed zone, or the exported page size does not match what KDP expects.
The traditional fix is to rebuild or adjust the layout in software such as InDesign or Affinity Publisher, then re-export. That works — but it is slow if you are not already fluent in print layout.
InkAlign is built for authors who already have an interior PDF and need it to line up with standard KDP-style paperback trims: margins, bleed, gutter by page count, and print-safe processing. You upload your file, run a free scan to see what would fail automated checks, then export a corrected interior when you are ready — without installing a desktop suite.
