PDF Compress
Shrink a scanned PDF (certificate, marksheet, ID proof) to fit an exam form's upload limit — processed entirely on your device, nothing is uploaded anywhere.
This works by converting every page to a compressed image and rebuilding the PDF — it's built for scanned documents. Text stops being selectable/searchable afterward, and on a typed/vector PDF (not a scan) it can make the file bigger, not smaller — we'll tell you if that happens. Nothing is uploaded — everything runs on your device.
Common Questions
- How does this PDF compressor work?
- It converts each page of your PDF into a compressed JPEG image and rebuilds a new PDF from those images, lowering quality step by step until it's under your target size. This works well for scanned documents and certificates.
- Will my PDF's text still be selectable after compressing?
- No — every page becomes an image, so text is no longer selectable or searchable. If your original PDF is mostly typed text or vector graphics (not a scan), this can make the file bigger instead of smaller — the tool will tell you if that happens, and in that case you should just upload the original file.
- Does this upload my document anywhere?
- No. Rendering and compression happen entirely in your browser — the file is never sent to a server.
