Looking for a PDF compressor online that doesn’t send your docs to a stranger’s server? Imgician’s free compressor runs entirely in the browser. You set a size in KB; it re-renders pages until the download fits.
Use the free PDF compressor
- Go to Compress PDF — Imgician’s PDF compressor.
- Drop your file (scans, photo PDFs, and packages all work).
- Type a target in KB (
500,1024,2048…). - Cast the spell.
- Download the smaller PDF.
Need a preset? Jump straight to 300KB, 500KB, 1MB, email, or WhatsApp.
Why this compressor vs desktop apps
- No install, no Adobe subscription
- Works on phone Safari/Chrome
- Private by design — files stay in the tab
- Target-size workflow (not a vague “low/medium/high” slider)
