Frequently asked questions

Will text stay sharp?

Results depend on the file. Scanned or image-heavy PDFs shrink more; text-only files may shrink less.

Why is compression slow?

Each page is rendered and recompressed in your browser. Large page counts take more time.

Can I undo compression?

Keep your original file. Compression creates a new download and does not overwrite the source.

Is there a size limit?

Limits depend on your device memory. Very large PDFs may fail on low-RAM phones.
