Free PDF tools
Reduce PDF size on your device. Best for scans and image-heavy files.
Files stay in your browser — nothing is uploaded
Drop PDFs here or click to browse
Up to 20 files, 50 MB total. Password-protected PDFs are not supported.
Text-only PDFs may barely shrink. Scans and photos benefit most.
Comma-separated. Use 1-based page numbers.
How it works: Modern browsers run PDF processing locally using JavaScript. We never receive your files.
Limits: This is a free browser tool — not a replacement for desktop Ghostscript or commercial optimizers. Very large or complex PDFs may be slow on older devices.
