How it works
Process files without an upload queue
Each page is rendered and rebuilt as a compressed JPG image. This can substantially reduce scanned PDFs while preserving the visual page layout.

Private browser processing
Compress a PDF
Rebuild pages as optimized images to reduce large scanned or image-heavy PDFs.
Private by design. Processing happens in this browser. Your files are never uploaded to Tool Packer.
Important limitation
Keep the original file
Compression rasterizes every page. Selectable text, links, form fields, accessibility tags, signatures, and other interactive PDF features will not survive. Always review the result.
How to use it

Know before you start
Important limitations
- Rasterization removes selectable text, links, forms, tags, signatures, and other interactive features.
- Text-first or optimized PDFs may not become smaller.
- Fine print can soften at aggressive quality settings.
Common questions
Compress PDF FAQ
Why is this best for scanned PDFs?
Image-heavy pages provide the largest opportunity for downsampling and JPEG compression.
Will selectable text remain?
No. Every page becomes one raster image in the rebuilt PDF.
Can the result become larger?
Yes. A text-focused or already optimized PDF may grow after every page is converted to an image.
