Frequently asked questions
Why did my file barely shrink?
Text-only PDFs have little to compress. Try Maximum mode with Low quality; text then becomes an image.
Is this tool really free?
Yes. It is free with no signup, no watermark and no daily limits.
Are my files uploaded to a server?
No. All processing happens in your browser, so your files never leave your device.
