Frequently asked questions
How much smaller will my PDF get?
It depends on the file. Scanned or image-heavy PDFs often shrink a lot; PDFs that are mostly text may compress less.
Will the text still be selectable?
This compressor re-renders pages as images to maximise size savings, so text becomes part of the image. Keep your original if you need selectable text.
Which level should I choose?
“Recommended” balances size and quality. Use “More compression” for the smallest file, or “Less compression” to keep pages sharper.
Are my files uploaded to a server?
No. Every PDF tool here runs entirely in your browser using your device's own processing power. Your files never leave your computer, which makes it private and fast.
Is this tool really free?
Yes — it is completely free with no sign-up, watermarks or daily limits. You can process as many files as you like.
This tool processes your files locally in your browser and does not upload them anywhere. Always keep a copy of your original file.
