Their online portals have strict file size limits — and most scanned Aadhaar cards, PAN cards, and address proofs are too large. Here is how to compress them instantly for free.

How to Compress Aadhaar Card for KYC
The Aadhaar PDF downloaded from UIDAI is password protected and usually under 1 MB — most banks accept it directly. However, if you have a scanned copy of your Aadhaar card, it may be 2–5 MB. Upload the scanned Aadhaar PDF to pdfvista.com/compress-pdf and use High compression to bring it under 1 MB. The QR code and all details remain clearly readable after compression.
Tips for Bank KYC Uploads
- ✓Download your Aadhaar directly from UIDAI (myaadhaar.uidai.gov.in) — the official PDF is already optimized and password protected.
- ✓For PAN card, take a clear photo in good lighting rather than scanning — smartphone photos compress better.
- ✓Ensure all 4 corners of the document are visible in the scan or photo.
- ✓Black and white scans are smaller than colour scans — use black and white mode on your scanner for address proofs.
- ✓For bank statements, compress only the required pages — usually the first page with your name and account number.
Frequently Asked Questions
Is it safe to upload my Aadhaar and PAN card to an online tool?
Yes. PDF Vista processes files entirely in memory and deletes them immediately after your download. No files are stored on any server. Your documents are never accessed or retained.
Will compressing my Aadhaar make it invalid for KYC?
No. Compression only reduces the file size — it does not alter any information, QR codes, or data in the document. The compressed Aadhaar is as valid as the original for KYC purposes.
What format should I use for bank KYC documents?
Most banks accept PDF and JPEG formats. PDF is preferred for multi-page documents like bank statements and rent agreements. JPEG is better for single-page documents like PAN card and Aadhaar.
My bank says the file must be under 500 KB but my PDF is 3 MB — will this work?
Yes. Use Maximum (100%) compression. A 3 MB scanned document can typically be compressed to under 300 KB while remaining fully readable.
Is PDF Vista free to use?
Yes — completely free. No sign-up, no watermark, no payment. Compress as many documents as you need.
