What you can do

Opens with Under a size set to 500 KB: choose your PDF and press Compress PDF.
NightOwl tries a few settings and keeps the sharpest file under 500 KB.
It aims under 500 KB counted as 1 KB = 1,000 bytes, so the file passes forms that count either way.
Text in the file stays searchable, and your edits and redactions are kept.
If it cannot get there while the text stays readable, it says so, gives you the smallest file it can make, and offers Split PDF.

How to do it

Open Compress PDF to 500 KB and choose your PDF.
Check that Under a size shows 500 KB, then press Compress PDF.
See the new size, then Download.

Good to know

Portals that take a short document, such as an agreement, a set of certificates or a few pages of a scan, often allow 500 KB.
Measured on made-up documents: five greyer scanned pages of 1 MB came to 432 KB at High quality, the sharpest setting.
Only pictures are made smaller: a file that is mostly typed text, or already small, may not shrink much.
Works in your browser. Scans you choose to read on our India server aren’t kept. Private mode keeps everything on your device.
