Yes, 100% free with no watermark, no signup, and no limits.
No. All compression happens locally in your browser. Your files never leave your device.
Depending on the PDF, you can reduce file size by 30-70%. Image-heavy PDFs see the biggest reduction.
No. Text remains sharp. Only images inside the PDF are re-compressed based on your quality setting.
Password-protected PDFs must be unlocked first. Remove the password in your PDF reader, then compress here.
No hard limit, but very large files (100 MB+) may be slow depending on your device. For best results, compress files under 50 MB.
