Frequently asked questions
How much smaller will my PDF be?
It depends on the content. PDFs with many photos or scans often shrink by 50–90%. Text-only PDFs are usually already compact.
Will compression reduce the quality?
Low compression keeps images almost untouched. Medium is a good balance. High compression gives the smallest file with visibly lower image quality.
Is Compress PDF free?
Yes. Compress PDF is completely free. There is no registration, no subscription and no watermark on your files.
Are my files safe?
Whenever possible your file is processed directly in your browser and never leaves your device. When server processing is needed, files are deleted automatically right after processing.
Does it work on my phone?
Yes. The tool works in any modern browser on Windows, macOS, Linux, Android and iPhone – nothing to install.
