Drag your file into the editor — scans and image-heavy files compress best.
Click Compress and choose a quality level. Higher quality keeps detail; lower quality saves more space.
The editor shows the before/after size (e.g. 18 MB → 2.1 MB) and downloads the compressed copy.
The actual editor — no install, it runs right in your browser.
Scanned documents routinely shrink 70–90%, comfortably under 10 MB and 25 MB email attachment limits.
An adjustable quality slider and DPI selector let you trade sharpness for size — with the result shown instantly.
Other compressors upload your file and cap free usage. Here compression is local and unlimited.
It depends on content. Scans and photo-heavy PDFs often shrink by 70–90%. Already-optimized text PDFs may not shrink much — the editor tells you honestly.
This compressor re-renders pages as images for maximum savings, so text isn't selectable in the compressed copy. Keep the original if you need selectable text — or run OCR on the compressed file.
No hard limit. Because compression runs on your device, even very large files work on a typical laptop.
