PDF Compressor
Reduce PDF file size entirely in your browser.
How this works (Browser Limitation)
Because this runs locally, we cannot rewrite the internal PDF objects like a desktop tool. Instead, we convert each page into a compressed image and build a new PDF. Resulting text will not be selectable. This is best for scanned documents, forms, or image-heavy PDFs.

How to Compress PDF Files Securely
Compressing PDFs locally ensures that your private documents never leave your computer. Need to reduce the size of a PDF document but concerned about privacy? Most online PDF compressors require you to upload your sensitive documents to their servers. Our tool processes your files 100% locally in your browser.
Best Use Cases for Client-Side Compression
- Scanned Documents: If your PDF is made of scanned images or photographs, our rasterization engine will significantly reduce its size.
- Image-Heavy Portfolios: Shrink large portfolios down to email-friendly sizes.
Note: Because this tool converts PDF pages into compressed images, it works best on visual documents. If you have a purely text-based PDF (like an exported Word document), this method might actually increase the file size or make text unselectable. Adjust the resolution scale and image quality sliders to find the perfect balance!
