Is the PDF compressor free to use?

Yes. It’s free and runs in your browser - no signup, no install.

How much can I shrink a PDF?

It depends on the source. PDFs with many embedded images often drop 40–80% in size. Text-only PDFs are already compact and see smaller savings.

Can I compress a PDF to a specific size (e.g. 2 MB)?

Yes. Enter the target in MB and the tool adjusts the compression level to aim for that limit. If the target is very aggressive, try Strong or run OCR on scans first.

Will the text stay searchable?

Yes. The text layer is preserved. Bookmarks and internal links also stay intact.

Is the compressed PDF still print-quality?

Light keeps print quality. Balanced is fine for most uses. Strong resamples images more aggressively - great for screen, not recommended for professional printing.

Does the tool upload my PDFs to a server?

Compression runs in your browser. Files are processed locally and not stored on our servers.
