FAQ

Are files uploaded?

No. Compression happens entirely in your browser.

Will text stay selectable?

This mode rasterizes pages for size; text becomes part of the image. Keep a copy of the original if you need selectable text.

Is there a size limit?

Browser memory is the limit — hundreds of pages may be slow on phones.

Is it free?

Yes.
