Frequently asked questions

Will my PDF's text still be selectable after compressing?

No — each page is re-rendered as an image to shrink the file, so the compressed PDF's text is no longer selectable or searchable. If you need to keep text selectable, this isn't the right tool.

Is my PDF uploaded to a server?

No. Compression happens entirely in your browser — your file never leaves your device.
