Government and exam portals almost always cap PDF uploads at a strict size — often 200KB to 1MB for application forms, mark sheets, or category certificates. A phone-scanned document is usually 3-10MB straight out of the camera, which the portal rejects outright with no useful error message beyond "file too large."
This tool compresses the PDF down to a target size you set, adjusting image quality and resolution while keeping the text legible. It runs entirely with your browser's PDF and Canvas APIs, so the document never leaves your device — useful when you're compressing a mark sheet or ID proof you'd rather not upload to a random online compressor.
If compression alone can't hit your target without becoming unreadable, the usual fix is re-scanning at a lower DPI (150-200 DPI is plenty for a form) rather than photographing at full camera resolution and compressing after.
No — it runs locally in your browser.
Settings are shown before you run the tool so you can see the trade-off before committing.
For text documents, 100-150KB per page is usually still fully legible after compression. Photo-heavy pages need more headroom — aim for at least 200KB per page if it includes a photograph or signature.
Some portals also check the file format strictly (PDF only, no renamed images) or reject password-protected PDFs. Confirm the file opens normally and isn't accidentally still an image file renamed to .pdf.
