Frequently Asked Questions
Is my document uploaded to compress it?
No. Compression runs entirely in your browser, so your file never leaves your device.
Why does the text become unselectable?
This tool rasterizes each page to an optimized image, which is what makes scanned documents much smaller. Because pages become images, any selectable text is flattened into the page. For text-based PDFs that are already small, compression may not help.
