Frequently asked questions

Are my files uploaded to a server?

No. Compression runs entirely in your browser using WebAssembly. Your PDF never leaves your device, which makes this safe for KYC, banking, and government documents.

How do you hit exactly 250 KB?

We re-encode each page as an image and search across quality and resolution settings until the rebuilt PDF lands at or just under 250 KB, keeping the best quality that still fits.

Is it really free with no watermark?

Yes. No sign-in, no per-hour task caps, no watermark, and no file-count limits, unlike most incumbents.

Will the text stay selectable?

When the file already fits or can be optimized losslessly, text stays sharp and selectable. To guarantee a smaller exact size we rasterize the pages, which is exactly what portal uploads need. If you need selectable text, keep your original.
