PDF Compressor
Shrink a PDF's file size by re-compressing each page as an image.
Reduce a PDF's file size by rendering each page as a compressed JPG and rebuilding the PDF from those — a real tradeoff (text stops being selectable, since pages become images), best for scanned documents or image-heavy PDFs rather than text reports.
Frequently asked questions
Will the text in my PDF still be selectable?
No — this is the key tradeoff. Every page is rendered as an image and rebuilt into a new PDF, so any selectable text or crisp vector graphics become a picture instead. It's a good fit for scanned documents or photo-heavy PDFs, not for text reports you'll want to copy from later.
Is my PDF uploaded anywhere?
No — reading, compressing, and rebuilding the PDF all happen in your browser using JavaScript libraries. The file never leaves your device.
How much smaller will my file get?
It depends heavily on the original — a PDF that's already mostly compressed images won't shrink much, while a PDF exported at very high resolution can shrink dramatically. The tool shows you the exact before/after size so you can judge the result before downloading.
