How to compress a PDF to 500 KB

Tap Choose PDF and pick your file.
The target is already set to 500 KB – change it if your form asks for another size.
Tap Compress PDF. The tool tries smaller settings until the PDF fits.
Check the new size, then Download.

Questions

Will the text stay sharp?

Target size turns each page into an image, so the text can no longer be selected or searched. It still reads well on screen for scanned forms, certificates and mark sheets.

What if it cannot reach 500 KB?

Then the PDF has too many pages or pictures for that size. The tool gives the smallest result and tells you. Try removing extra pages first with Extract pages.

Is my PDF uploaded?

No. Everything happens inside your browser on your own device.
