How to Crop & Resize Images to Any Ratio
Passport, A4, Instagram, custom — crop anything to the exact shape you need.
Cropping isn't just about making images smaller — it's about controlling composition and matching exact ratios: passport 2×2, A4 documents, Instagram squares, YouTube 16:9.
The ratio-first workflow
- 1
Pick the ratio first
Choose a preset — passport, A4, Instagram, YouTube — or enter a custom width × height.
- 2
Drag the crop window
Position the frame over the best part of the image; the ratio stays locked.
- 3
Set output dimensions
Define exact pixel output (e.g. 600 × 600) for print or platform specs.
- 4
Export
Download as PNG, JPEG or WEBP with quality control.

Common ratio recipes
| Use case | Ratio | Typical pixels |
|---|---|---|
| Passport photo (US) | 1:1 | 600 × 600 |
| A4 document | 1 : 1.414 | 1240 × 1754 |
| Instagram post | 1:1 | 1080 × 1080 |
| YouTube thumbnail | 16:9 | 1280 × 720 |
| Twitter header | 3:1 | 1500 × 500 |
Always work from the original
Crop from your highest-resolution master, not from an already-exported low-res file.
