FAQ
Frequently asked questions
How much smaller will my PDF get?
Depends on the content. Image-heavy PDFs often shrink 50–80%; text-only files less.
Will the quality drop?
Pick "Better quality" to keep visuals sharp. "Smaller" trades visual fidelity for max compression.
Is Comprimir PDF really free?
Yes — every tool on PDFLabz is free with no daily limit, no account, and no watermark.
Are my files private?
100%. This tool runs entirely in your browser using JavaScript. Your files never reach our servers.
Is there a file size limit?
Up to 100 MB per file. Larger files just take longer because everything runs locally on your device.
Do I need to install anything?
No installation. Any modern browser (Chrome, Firefox, Safari, Edge) on any OS works.
