Questions about compress pdf
How does it compress?
It re-renders each page as an image at a lower resolution. This shrinks scanned and image-heavy PDFs a lot.
Will the text still be selectable?
No. Because pages become images, the text can no longer be selected or searched. Keep your original if you need that.
Is my file uploaded?
No. Compression happens entirely in your browser.
