How to compress a PDF to 500 KB
- Choose or drop your PDF.
- Check the target: 500 KB is already filled in.
- Click Compress PDF; the lightest settings are tried first.
- Download the PDF and upload it.
Why 500 KB?
500 KB is a common limit on application portals and older systems, and it keeps email attachments quick to send. Scanned documents are often 2–10 MB, so they need real compression.
If it still won’t fit
- Try Grayscale PDF first: grey images are much smaller.
- Remove pages you don’t need.
- Rescan at 150–200 dpi.

Frequently asked questions
Will the text stay selectable?
Usually yes. Pages are turned into images only if nothing else reaches 500 KB, and the result tells you when that happened.
Is it safe for personal documents?
Yes. Compression runs in your browser, so nothing is uploaded.
