Compress PDF to 500KB — frequently asked questions

Is 500 KB better than 100 or 200 KB?+

It gives the compressor more headroom, so images generally come out sharper. Use it whenever the form's limit allows it.

Will my file actually reach exactly 500 KB?+

It aims for under 500 KB, not exactly 500 KB — the result is usually a bit smaller than the limit.

Do you upload my files to a server?+

No — every tool here processes your files entirely on your device, and nothing is uploaded to a server. The only exception is the AI tools, which send the extracted text (not the file) to Claude to do their work.

Is there a file size limit?+

There's no artificial limit we impose, but since processing happens in your browser, very large files (500+ MB or 1,000+ pages) are limited by your device's memory rather than by us.
