Frequently Asked Questions

How much smaller will my PDF get?+

Scanned and image-heavy PDFs often shrink by 50–70%. Text-only PDFs that are already efficient shrink less — sometimes they are already optimal.

Why do I need to compress a PDF?+

E-mail providers commonly cap attachments at 10–25 MB, and application portals often enforce strict upload limits. Compression gets your document under those thresholds.

Does compression affect quality?+

Pages are re-encoded at a quality tuned for reading and printing. Fine details in photos may soften slightly; text remains clearly legible.

Is the text still selectable afterwards?+

This compressor rasterizes pages for maximum size reduction, so text becomes part of the page image. If you need selectable text, keep the original for editing purposes.
