Quick answers about privacy, limits and results. Need more help? Contact us.
Will text stay selectable?
No. Pages are rebuilt as grayscale images. Use OCR PDF afterwards if you need searchable text.
Does it make the file smaller?
Often yes for colour photos and scans, but text-only files can grow because pages become images.
Are my files uploaded to your server?
No. This tool runs entirely in your browser, so your files never leave your device.
Is it free?
Yes. Every browser tool is free to use without sign-up or watermarks.
