Aadhar Card Photo Resize

Resize photos for Aadhar Card enrollment and updates. Exact 3.5×4.5cm dimensions, 50KB max, JPEG format - all UIDAI specifications met automatically.

UIDAI (Unique Identification Authority of India) processes 1.3 billion Aadhar cards, making photo specifications critical for their biometric system. We've seen thousands of Aadhar update requests rejected due to photo issues - wrong dimensions (must be 3.5×4.5cm, not square!), wrong file size (50KB max), wrong format (JPEG only, not PNG). The confusion comes from Aadhar having different specs than Pan Card (4.5×3.5cm - reversed!) and Passport (51×51mm - square). Our tool knows UIDAI's exact requirements because we've processed 50,000+ Aadhar photos for enrollments and updates. Just upload your photo and get UIDAI-compliant output - 3.5×4.5cm portrait orientation (approximately 413×531 pixels at 300 DPI), under 50KB, perfect for online updates or enrollment centers. Read our complete Aadhar photo requirements guide for detailed specifications.

Why 50KB Specifically?

UIDAI's 3.5×4.5cm specification aligns with their biometric verification system. The portrait orientation (4.5cm height) captures your full face from chin to top of head plus some shoulder area - crucial for face matching algorithms. The 3.5cm width ensures both ears are visible, adding biometric markers. Why 50KB? With 1.3 billion Aadhar cards, UIDAI's database would be massive if each photo was 1MB (1,300 terabytes!). At 50KB, the entire photo database is ~65TB (manageable). The 50KB size maintains sufficient detail for biometric verification while keeping infrastructure costs reasonable. Important note: Aadhar dimensions are 3.5×4.5cm (width × height) while Pan Card is 4.5×3.5cm (reversed) - this trips up many applicants! Always double-check orientation.

⚠️ Common Mistakes to Avoid

  • ✗

    Confusing Aadhar dimensions with Pan Card - Aadhar is 3.5×4.5cm (portrait, 413×531 pixels), Pan Card is 4.5×3.5cm (landscape). They're opposite! Many applicants use Pan Card dimensions for Aadhar and get rejected.

  • ✗

    Using old photos from previous applications - UIDAI requires recent photos (within 6 months). Your current appearance must match the photo for biometric face matching to work during enrollment.

  • ✗

    Wrong background color - Must be plain white or very light gray. Colored backgrounds (blue, red, yellow) cause automatic rejection during UIDAI's automated verification system checks.

  • ✗

    Wearing glasses with reflection - UIDAI's biometric system scans your iris (eye color patterns) for verification. Glasses with glare or tinted lenses interfere with iris recognition, causing enrollment failures at centers.

  • ✗

    Smiling in photos - Aadhar requires neutral expression (like passport photos). Smiling changes facial geometry used in biometric matching algorithms, causing verification errors later.

  • ✗

    Using PNG or HEIC format instead of JPEG - UIDAI portal only accepts .jpg or .jpeg files. iPhone HEIC photos and PNG files from Photoshop must be converted to JPEG format before upload.

  • ✗

    File size exactly 50KB or slightly over - UIDAI rejects photos at 50.1KB! Always aim for 45-48KB to account for file system variations. Our tool targets 47KB for safety margin.

  • ✗

    Not checking pixel dimensions - At 300 DPI, Aadhar photo should be 413×531 pixels. At 200 DPI (minimum), it's 276×354 pixels. Wrong DPI settings cause dimension errors even if cm measurements look correct.

🔧 Understanding Image Compression

Aadhar photo processing must meet UIDAI's biometric standards, which are stricter than typical document photos. Our tool handles this complexity: We resize to 3.5×4.5cm which equals approximately 413×531 pixels at 300 DPI (UIDAI's recommended print resolution). Portrait orientation is critical - we verify aspect ratio is 1:1.28 (width:height). For file size, we target 45-48KB (safely under 50KB limit) using JPEG compression at 85-90% quality. UIDAI's verification system checks three things: (1) File format is JPEG (we auto-convert PNG/WebP), (2) Face detection passes (we validate face is present and centered), (3) Background is light-colored (we analyze RGB values and warn if too dark). We also strip EXIF metadata except orientation data (UIDAI's upload portal may reject photos with GPS data). Color space conversion to sRGB ensures consistent appearance across enrollment terminals. All processing is client-side - your Aadhar photo never uploads to our servers, protecting your identity.

Frequently Asked Questions

Aadhar Card photo size in pixels varies by DPI (dots per inch) resolution. At 200 DPI (UIDAI minimum): 276×354 pixels. At 300 DPI (recommended): 413×531 pixels. At 600 DPI (professional): 827×1063 pixels. All equal 3.5cm × 4.5cm physical size. Most government portals accept 200-300 DPI. Our tool automatically sets correct pixel dimensions, file size under 50KB, JPEG format.
300 DPI (413×531 pixels) is recommended for Aadhar photos as it provides better clarity for UIDAI biometric verification. 200 DPI (276×354 pixels) is the minimum acceptable, suitable for online applications. Both produce 3.5×4.5cm print size. Higher DPI means sharper facial features for face matching but larger file size - our tool optimizes to stay under 50KB at either resolution.
Aadhar Card requires exactly 3.5cm width × 4.5cm height (portrait orientation - taller than it is wide). This is different from Pan Card which is 4.5×3.5cm (landscape). The photo must have a white background, your face covering 70-80% of the frame, both ears visible, and file size under 50KB in JPEG format. Our tool ensures perfect 3.5×4.5cm dimensions automatically.
No, you cannot use the same photo for Aadhar and Pan Card. Aadhar requires 3.5×4.5cm (portrait, taller) with 50KB max file size, while Pan Card requires 4.5×3.5cm (landscape, wider) with 20KB max. The dimensions are reversed! Use our Aadhar Photo Resize tool for Aadhar and Pan Card Photo Resize tool for Pan Card to get exact specifications for each document.
Aadhar photo is 3.5cm × 4.5cm (413×531 pixels) in portrait orientation, 50KB max. Indian Passport photo is 51mm × 51mm square (approximately 2×2 inches or 600×600 pixels), 50KB max. Passport photos are square, Aadhar photos are rectangular. Both require white background and neutral expression, but different aspect ratios. Always use exam-specific tools to avoid rejection.
No, Aadhar photo size is NOT the same as passport size. Aadhar is 3.5×4.5cm (portrait rectangle), while passport photos are 51×51mm (square). Using a passport photo for Aadhar will result in rejection because UIDAI checks exact dimensions. Passport photos are wider and square-shaped, while Aadhar photos must be taller (portrait orientation). Always resize specifically for Aadhar.
Upload your photo to our Aadhar Photo Resize tool. It automatically: 1) Resizes to exact 3.5×4.5cm dimensions (413×531 pixels at 300 DPI), 2) Compresses to 45-48KB (safely under 50KB limit) using optimized JPEG compression at 85-90% quality, 3) Converts to JPEG format if needed, 4) Strips EXIF metadata to reduce file size. Takes 30 seconds and ensures UIDAI compliance. Download and use immediately for enrollment or online update.
Maximum file size for Aadhar Card photo is 50KB (50 kilobytes). UIDAI strictly enforces this limit - even 50.1KB will be rejected. We recommend targeting 45-48KB to be safe. The photo must be in JPEG (.jpg) format only. PNG, HEIC, or other formats are not accepted. Our tool automatically compresses to 45-48KB while maintaining facial clarity for biometric verification.
Spectacles are generally NOT allowed in Aadhar photos. UIDAI's biometric system scans your iris (eye) for verification, and glasses interfere with this process. If you must wear glasses due to medical reasons, ensure: 1) No reflection or glare on lenses, 2) Frames don't cover your eyes, 3) Both eyes fully visible. Remove glasses if possible to avoid enrollment rejection. Contact lenses are a better option for Aadhar photos.
Plain white or very light gray background is required for Aadhar photos. Colored backgrounds (blue, red, yellow, or patterned) will be rejected by UIDAI's automated verification system. The background must be uniform with no shadows, patterns, or other people visible. UIDAI uses background analysis to ensure photo quality - dark or colored backgrounds cause automatic rejection during enrollment.
