One megabyte is the most common upload limit on the web – job applications, tax and visa forms, school portals. This page is preset to 1 MB: PDF Converter keeps fonts and vector graphics intact, downsamples only images stored at a higher resolution than the page needs, and stops at the first version under 1 MB.

How to compress PDF to 1 MB
- Add one or more PDFs – the limit is already 1 MB.
- Press Compress. Gentle settings are tried first.
- Download each file; the note shows the size before and after.
Good to know
- Photo-heavy brochures and multi-page scans often shrink by 70–90% while still looking good on screen.
- Text-only PDFs above 1 MB are usually bloated by embedded fonts or duplicate objects – lossless restructuring alone often fixes them.
- Files already under 1 MB are returned unchanged.
Frequently asked questions
How do I make a PDF under 1 MB?
Upload it here and press Compress – the target is set to 1 MB and the tool compresses only as much as needed.
Why is my PDF so large?
Usually because of high-resolution photos or scans. A page scanned at 600 dpi can be several megabytes; 150 dpi is plenty for reading on screen.
Will compression affect printing?
At 1 MB most documents still print well. For print-critical files choose Light in Compress PDF instead.
Does this work on a phone?
Yes. It runs in any modern mobile browser, and files stay on your phone.
