Compress PDF to 1MB — frequently asked questions

Is 1 MB a safe default?+

For most multi-page documents, yes — it's usually enough room that the quality loss is barely noticeable, unlike the more aggressive 100 KB or 200 KB targets.

What if my file is already under 1 MB?+

It's returned as-is (or lightly re-compressed) — there's nothing to shrink.

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.
