About this tool
Reduce a PDF file size by recompressing the images embedded inside it. Works on one file or many at once. It runs entirely in your browser using open-source PDF libraries, so your document is processed on your own device and never uploaded to a server. That makes it a fast, private option any time you need to reduce PDF file size by re-compressing images. Bulk supported.
How to use it
- Upload one PDF, or several at once for bulk compression.
- Choose a compression level for the embedded images.
- Download the smaller file(s).
Tips
- PDFs made mostly of text won't shrink much, since compression targets embedded images.
- Try the bulk option if you have a folder of similar scanned documents to shrink at once.
FAQ
Will this reduce the size of a text-only PDF?
Not much — this tool targets embedded images, so text-heavy PDFs see little change.
