Files stay in your browser — nothing is uploaded
Privacy First
Your file is processed entirely in your browser. Nothing is uploaded to any server.
Upload a PDF file and choose a quality preset to reduce its file size.
This tool renders each page of your PDF to a canvas, re-encodes it as a compressed JPEG image at the chosen quality level, then assembles all pages into a new, smaller PDF. Everything happens in your browser — no files are uploaded to any server.
Step 1
Drop or select your PDF file.
Step 2
Choose a compression preset: Maximum, Balanced, or High Quality.
Step 3
Click Compress — each page is rendered and re-encoded at the target quality.
Step 4
Download the smaller PDF and review the before/after size comparison.
Note
Because pages are rendered as images, text in the compressed PDF will no longer be selectable or searchable. Use the High Quality preset for text-heavy documents to preserve readability.
