Compress PDF to 500 KB
Many strict online forms cap uploads at 500 KB. We compress just enough to get under that line without ruining readability.

What this does
SubmitReady searches for the lightest compression setting that still brings your file under 500 KB, re-encoding embedded images and repacking the document structure. It never applies more compression than necessary.
When you need it
500 KB is a common ceiling for visa applications, government e-services, scholarship portals, and some recruitment systems. If your scanned passport or certificate is a few megabytes, this gets it under the line.
What if 500 KB isn't reachable?
If the document can't be brought under 500 KB while staying legible, SubmitReady tells you plainly and gives you the smallest readable version it could produce, rather than pretending to succeed.

Frequently asked questions
- Why 500 KB specifically?
- It's one of the most common hard limits on government and visa submission portals.
- Will my scanned document still be readable?
- Yes — we stop reducing quality once the file is under target, and never compress below a legibility floor.
