How it works (3 steps)
Upload a PDF
The target size is preset to 500KB; change it if your portal allows a different limit.
Automatic compression
Images are re-encoded page by page with a binary search on quality until the output fits under 500KB.
Download the result
Before/after sizes are shown. If 500KB is unreachable we report the minimum achievable size instead of outputting an oversized file.

FAQ
University applications, job portals expecting resume attachments, online assignment submissions and some banking/insurance uploads — looser than 200KB, but scans still overshoot it easily.
Try it ↑A 1–3 page resume or certificate scan is usually fine; for long transcripts, split out only the pages you need first.
Try it ↑We clearly report the minimum achievable size rather than silently producing an oversized file; use the Split tool to reduce page count first.
Try it ↑No — compression runs entirely in your browser.
Try it ↑No. Any change to a signed PDF (merging, compressing, watermarking…) invalidates the existing digital signature — that is the tamper-proof design of PDF signatures, not a limit of this site. Process first, then sign.
Try it ↑Yes — and you can verify it: the tool runs on open-source in-browser engines (pdf-lib, pdf.js, Tesseract OCR…) on your own device. Open DevTools → Network while processing and you will see no file upload requests.
