Compress Aadhaar Card to 100KB — Online
Overview
Some exam registrations, school and college forms, and government portals cap the Aadhaar upload at 100KB, which is tighter than most scans start out at. PDF Mavericks compresses your Aadhaar card PDF toward a 100KB target directly in your browser, so a document with your Aadhaar number and photo never leaves your device. Use high compression, download, and confirm the size before upload. A single-page Aadhaar usually reaches 100KB in one pass, and trimming to just the Aadhaar page handles the rest.
How to Use This Tool
Upload your Aadhaar PDF, pick High compression, download. If still over 100KB, the tool will suggest splitting or removing the second page.
- Open the Compress PDF tool - no upload, no account.
- Add your Aadhaar card PDF.
- Choose 'High' compression to push toward 100KB.
- Download and confirm the file is under 100KB.
- If it is close but over, keep only the Aadhaar page and compress again.
Why some forms cap Aadhaar at 100KB
Exam boards and admission portals handle a very high volume of uploads in short windows, so they set tight per-file caps to keep the system responsive. A 100KB Aadhaar limit is on the strict end but appears on several forms. A normal scan starts well above this, so compression is needed.
The size in an Aadhaar PDF is almost all image data, so high compression removes the most weight while keeping the number readable.
Getting from over-the-limit to under 100KB
First make sure you are compressing a single Aadhaar page. A multi-page PDF is much larger, and most forms only want the one page. Split it out, then compress.
If the scan is very high resolution, a grayscale re-capture before compressing removes color data you do not need for an identity document and helps you clear 100KB comfortably.
100KB, 50KB, or a looser cap?
If your form is even tighter, the 50KB guide pushes reduction further while keeping the QR scannable. If it allows more headroom, the 200KB guide keeps the scan crisper. Use the guide that matches your portal's exact stated limit rather than over-compressing.
Your Aadhaar stays on your device
Compression runs entirely in your browser using your device's own processing. Your Aadhaar card PDF is never uploaded to PDF Mavericks or any third party, and nothing is stored once you close the tab. For an identity document, that keeps the number and photo off every server.

Compress PDF →Frequently Asked Questions
How do I compress my Aadhaar card to 100KB?
Open the Compress PDF tool, add the Aadhaar PDF, choose 'High' compression, and download. Confirm it is under 100KB before you upload.
Is 100KB too small to keep the Aadhaar readable?
A single-page Aadhaar usually reaches 100KB with the number and QR still readable. If detail softens, submit only the one page so less compression is needed.
My Aadhaar is still over 100KB - what should I do?
Check you are compressing one page rather than a multi-page PDF, then compress again. Re-capturing a high-resolution scan in grayscale also brings it under the cap.
What if my form actually wants 50KB or 200KB?
Use the matching guide linked on this page - 50KB for the strictest fields, 200KB for banking and KYC. The same browser tool handles each target.
Is it safe to compress my Aadhaar here?
Yes. The file is processed entirely in your browser and never uploaded, so your Aadhaar details stay on your device with nothing stored afterward.
Can I do this on a phone?
Yes, it runs in any modern mobile browser with no app to install. Pick the Aadhaar PDF, compress, and check the size on the same device.
