Compress PDFs without uploading them anywhere
Email providers commonly cap attachments at 10–25 MB, and many government and job application portals limit uploads to as little as 2 MB. This tool re-renders your PDF's pages locally and rebuilds the document with optimized images, often cutting scanned documents down by 50–90%.
Because everything runs in your browser, it's safe to compress bank statements, signed contracts and other documents you'd never want sitting on a stranger's server. One honest caveat: the compressed PDF is image-based, so text won't be selectable afterwards — a worthwhile trade when you need to hit a size limit.
Frequently asked questions
How does this work without uploading my file?
Each page is re-rendered in your browser and the document is rebuilt with optimized images at your chosen quality. Nothing is sent to a server.
Will compressing reduce quality?
There's some trade-off. "High quality" is usually indistinguishable for reading and printing; "Smallest size" is for squeezing under upload limits. Text won't be selectable in the compressed file.
How much smaller will my PDF get?
Scanned and image-heavy PDFs often shrink 50–90%. The tool shows you the exact before and after size, so you can try a different level if needed.
