Frequently asked questions
Is compressing a PDF free?
Completely — no signup, no watermark, no limit. There is no server, so there is nothing to charge for.
Is my PDF uploaded?
No. Compression runs entirely in your browser. Your PDF never leaves your device.
Will the text still be selectable?
No — this light compressor flattens each page to an image to shrink the file, so the text becomes part of the picture and is no longer selectable or searchable. It is best for scans and image-heavy PDFs. We tell you this up front because we would rather be honest than surprise you.
Why didn't my PDF get much smaller?
Text-only PDFs are already tiny and compress poorly when flattened to images, so you may see little or no gain. Image-heavy PDFs and scans shrink the most.
