|---|---|
| Passport photo (India) | 35×45 mm (200×230 px at 200 DPI) |
| Aadhaar card photo | Max 50KB, JPEG |
| WhatsApp DP | 640×640 px recommended |
| Facebook profile picture | 180×180 px (displays 170×170) |
| Instagram post | 1080×1080 px (square) |
| LinkedIn profile | 400×400 px minimum |

Resize vs Compress — What's the Difference?
Many people confuse resizing with compressing. They are different operations:
- Resizing changes the pixel dimensions (width × height). Makes the image physically smaller or larger.
- Compressing reduces file size (KB/MB) without necessarily changing dimensions, by removing data.
If a form says "max 200KB" but doesn't specify dimensions, you need compression. If it specifies exact pixel dimensions, you need resizing. Sometimes you need both.
Tips to Resize Without Losing Quality
- Always resize down, not up — Enlarging a small image makes it blurry. Start from the highest quality source.
- Use PNG for graphics — PNG is lossless; JPG loses quality with each save.
- Maintain aspect ratio — Stretching an image to non-proportional dimensions looks unnatural.
- Resize before cropping — For passport photos, first resize, then crop to exact dimensions.
