❓ FAQ

Will text become blurry after compression?

No. This tool primarily reduces the size of embedded images. Text content remains sharp. However, scanned PDFs (image-based) may lose clarity at lower quality settings.

What quality setting is recommended?

For most documents, 75-85% quality provides a good balance — preserving visual quality while reducing file size by 40-60%. For archival purposes, 30-50% is acceptable.

Why didn't my file size decrease much?

If your PDF is mostly text with few images, compression will have limited effect. Text-based PDFs are already small. Compression works best on image-heavy PDFs.

Can I compress encrypted PDFs?

No. Encrypted PDFs cannot be read in the browser. Please unlock the PDF first, then use this compressor.

Is it safe and private?

Yes. All processing is done locally in your browser. Your files never leave your device. You can even use it offline after the page loads.
