Which level should I use?
Balanced suits most documents. Strong gives the smallest files for scans and photos. Lossless keeps text selectable with a smaller saving.
Will my text stay selectable?
Lossless keeps everything. Balanced and Strong re-encode pages as images to save more space.
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.
