Frequently asked questions

How much smaller will it get?

Scanned and image-heavy PDFs often shrink dramatically. Lean, text-only PDFs are already efficient — we won't inflate them.

Will text stay selectable?

Compression rasterises pages, so text becomes part of the page image. It's ideal for scans and image-heavy files; for text PDFs that are already small, we leave them as-is.

Is my file uploaded?

No — compression runs entirely in your browser, so your PDF never leaves your device.
