›How it works
SubmitReady re-encodes large embedded images at a smaller size and repacks the document. Text and vectors stay untouched, so nothing gets blurry. If a PDF has no compressible images, gains will be small — we won't pretend otherwise. Need an exact ceiling instead? Use Compress PDF to 500 KB, 1 MB, or 2 MB.
Frequently asked questions
- Will compressing reduce quality?
- Only image quality inside the PDF may be reduced, and only as much as needed. Text stays crisp because it's never rasterized.
- Is there a file size limit?
- Files up to 150 MB are supported, since everything runs in your browser's memory.
