Common Aadhaar Upload Rejections & Quick Fixes
Avoid common paper feed errors, scaling mistakes, and upload rejections:
Uploading 2 Separate Single-Side PDFs
Govt portals offer only one file attachment slot for Identity Proof. Submitting only the front side results in instant application rejection for missing address proof.
File Size Exceeding 200KB Limit
Raw smartphone camera photos range from 3MB to 8MB. Govt upload scripts drop files over 200KB. Use our built-in smart compression to stay safely under the cap.
Over-Compressing into Pixelated Artifacts
Excessive lossy compression corrupts the 2D secure QR code. Our adaptive encoder retains high contrast across QR zones while compressing blank page whitespace.
Cropping Out Care Of (C/O) or Pincode
Cropping too closely to the card border frequently cuts off the PIN code or father's name line. Always leave a 2mm border margin around the outer card perimeter.
Frequently Asked Questions
Comprehensive technical, print lab, and operational answers
Q1.Why do government portals require Aadhaar front and back on a single page?
Portal upload systems (such as EPFO UAN portal, Passport Seva, Indian Railways, and banking KYC forms) provide a single document upload field. They require both identity proof (front with photo and DOB) and address proof (back with address and QR code) on one single viewable page.
Q2.How does this tool guarantee the output PDF is under 200KB?
Our client-side compression pipeline utilizes WebAssembly and JBIG2/JPEG adaptive compression. It isolates the identity card regions, optimizes background white space, and sets the DPI to 200, resulting in a crisp document measuring between 120KB and 180KB.
Q3.Is it safe to upload my Aadhaar card to this website?
Yes, 100% safe. This tool runs entirely within your browser local sandbox using JavaScript and HTML5 Canvas. Your document images and Aadhaar details are never transmitted across the internet, logged into databases, or viewed by third parties.
Q4.Should I choose Side-by-Side or Stacked layout?
Side-by-Side (Horizontal) layout mimics the traditional Xerox photocopy format preferred by Indian banks and offline paperwork. Stacked (Vertical) layout is ideal for mobile viewing and official portals that display documents in a portrait viewer.
Q5.Can I convert my Aadhaar into a black-and-white Xerox photocopy?
Yes. Enable the "Grayscale / Xerox Mode" toggle. The engine strips color noise, balances contrast, and brightens background grays to produce a clean, authentic photocopy-style PDF.
Q6.Will the UIDAI secure QR code still scan after merging?
Yes. The engine preserves vector-level sharpness in high-frequency regions like the QR code matrix, allowing UIDAI verification apps, banking barcode scanners, and airport CISF scanners to read it without errors.
Q7.Can I use this merged PDF for bank KYC and SIM verification?
Yes. Major Indian banks (SBI, HDFC, ICICI, Axis, PNB) and telecom operators (Airtel, Jio, Vi) accept single-page Aadhaar front and back PDFs for digital e-KYC and re-KYC verification.
Q8.What if my Aadhaar scan is crooked or rotated?
The merger interface provides 90-degree rotation and fine angle alignment tools so you can straighten tilted camera photos before combining them onto the canvas.
Q9.Can I also print this PDF on standard A4 paper?
Yes. The generated PDF uses standard ISO A4 paper dimensions (210 x 297 mm). When printed at 100% scale, the card replicas match actual pocket card dimensions.
Q10.Do I need to install any software or pay a fee?
No software installation, extensions, or account sign-ups are required. The tool is 100% free and works seamlessly on Windows, macOS, Android, iPhone, and Linux browsers.
