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.
