Aadhaar-linked documents stay on your device. The compression runs in your browser — your Aadhaar number, address, and photo are never uploaded.

Aadhaar-linked portals enforce some of the strictest upload limits on the Indian web. Supporting documents — address proof, identity proof, birth certificates — typically need to fit under 200 KB, and the portal silently rejects anything over the cap.

A phone-scanned page usually lands between 2–8 MB, so reaching 200 KB requires real compression. Our size-aware engine tunes resolution and quality together to lock onto the exact target while keeping text legible.

Common Aadhaar-related uploads with 200 KB caps:

- Address proof (utility bill, rent agreement, bank statement) - Identity proof (PAN card, passport, voter ID) - Birth certificates and date-of-birth proof - School or college leaving certificates - Photographs at portal-specified sizes

Why you don't want this on a third-party server.

An Aadhaar-linked document typically contains your Aadhaar number, PAN number, date of birth, permanent address, and often a photo. Taken together, that's a near-complete identity fingerprint. Most online PDF compressors upload your file to their servers — even the ones that say they delete it after processing have already transmitted, logged, and potentially cached your identity. This tool runs entirely in your browser; nothing reaches a server. Open DevTools → Network while compressing and you'll see zero upload requests for your file.

How to compress an Aadhaar supporting document:

1. Drop your scanned PDF above or tap to browse 2. Target is pre-filled to 200 KB 3. Our engine dials in on the exact target 4. Download and upload to the UIDAI or linked portal

Portal file-size limits verified as of July 2025. Always double-check the official portal for current limits.

Questions people ask.

Why does the Aadhaar portal cap uploads at 200 KB?
UIDAI and its downstream portals were built to handle very high concurrent submission volumes across patchy connections. Small files keep server-side processing and queueing reliable even under load.
My Aadhaar-linked scan is 4 MB. Will it fit under 200 KB?
Usually yes for a single page. Our engine compresses the image data — both resolution and quality — to bring the output under 200 KB while keeping text legible. Multi-page documents may need to be split first — use the Split tool to extract just the page the portal wants.
Is it really safe to compress an Aadhaar-linked document here?
Yes. The entire pipeline runs in your browser via WebAssembly. Your Aadhaar number, PAN number, address, and photograph never leave your device — no server request carries your file. You can verify this in your browser's DevTools → Network tab.
What if I can't get it below 200 KB?
The tool shows the smallest achievable size and stops instead of pretending. If the document still won't fit, try scanning at 200 DPI instead of 300, convert a colour scan to grayscale, or split a multi-page file and upload only the page the portal asks for.
