FAQ
- Are my PDFs uploaded to a server?
- No. Compression runs entirely in your browser with pdf.js and pdf-lib. Your files never leave your device.
- How small will my PDF get?
- It depends on the original. Scanned or image-heavy PDFs often shrink 70-90% on the Smallest preset. Text-only PDFs are already small, so savings are modest — the tool will tell you if the result is barely smaller.
- Will my text stay selectable?
- No. To reach the smallest size, pages are rebuilt as compressed images, so text is no longer selectable or searchable. Keep your original if you need to copy text.
- Which preset should I choose?
- Smallest size for sharing by email or chat, Balanced for everyday use, High quality when readability matters most. Lower the quality slider further if you need even smaller files.
- Is there a size or page limit?
- Yes: 50 MB per file and up to 200 pages. Large documents can be slow on phones — split them and compress in smaller batches if needed.
