Pixels, inches and DPI explained
Screens only care about pixels: a 1080 × 1080 image fills an Instagram post whatever its DPI. Printers care about inches: a 2 × 2 inch photo at 300 DPI needs 600 × 600 pixels. Use Print size when the result goes on paper or into a form that asks for inches or millimeters, and Pixels for anything shown on screen.
The formula is simple: pixels = inches × DPI. At 300 DPI, a 4 × 6 inch print needs 1200 × 1800 pixels; at 150 DPI it needs half that.
| Print size | Pixels at 300 DPI | Pixels at 150 DPI |
|---|---|---|
| 2 × 2 in (US passport) | 600 × 600 | 300 × 300 |
| 35 × 45 mm (most passports) | 413 × 531 | 207 × 266 |
| 4 × 6 in photo | 1200 × 1800 | 600 × 900 |
| 5 × 7 in photo | 1500 × 2100 | 750 × 1050 |
| 8.5 × 11 in page | 2550 × 3300 | 1275 × 1650 |
Social media image sizes
| Where | Size in pixels | Shape |
|---|---|---|
| Instagram post | 1080 × 1080 or 1080 × 1350 | 1:1 or 4:5 |
| Instagram, TikTok story or Reel | 1080 × 1920 | 9:16 |
| YouTube thumbnail | 1280 × 720 | 16:9 |
| LinkedIn banner | 1584 × 396 | 4:1 |
| X (Twitter) header | 1500 × 500 | 3:1 |
| Facebook cover | 851 × 315 | about 2.7:1 |

Resizing a photo for a US passport or visa
The US Department of State asks for a 2 × 2 inch color photo with the head between 1 and 1⅜ inches tall, and the online DV lottery and DS-160 visa forms take a square JPEG of at least 600 × 600 pixels. Choose the US passport preset: the picture is cropped to a square at 600 × 600 pixels with the top of the frame kept, so the head stays in view.
Resizing only changes size and shape. Background color, lighting and head position still have to meet the rules, so start from a photo taken against a plain white wall.
Making an image smaller in KB
Halving width and height cuts the number of pixels to a quarter, which usually brings the file down to a third or a quarter of its size. Set a maximum file size to go further: the resizer lowers JPG or WebP quality step by step until the file fits, and tells you if the limit can't be reached.
Frequently asked questions
How do I resize an image without losing quality?
Making an image smaller keeps it sharp because detail is only removed, not invented. Enlarging always looks softer. Save as PNG or as JPG at quality 90 or higher for the best result.
How do I resize a photo to 2 × 2 inches?
Choose the US passport preset, or Print size with 2 × 2 inches at 300 DPI. The photo is cropped to a square of 600 × 600 pixels and keeps the face near the top.
Can I resize many images at once?
Yes. Choose or drop as many images as you like; every one gets the same settings and you can download them together as a ZIP.
What does keep proportions mean?
Enter only the width or only the height and the other side follows automatically, so the picture is not squashed.
Why is my resized file bigger than the original?
Saving as PNG or at a very high JPG quality can make a file larger. Choose JPG or WebP, lower the quality a little or set a maximum file size.
Are my photos uploaded?
No. Resizing happens in your browser, so ID photos and personal pictures stay on your device.
