Guide
Resize image online
Resize images to a max box or exact pixels in your browser. Keep aspect ratio. Files never upload.
Max box vs exact
Fit inside max box scales down so width and height stay within your limits. Exact size targets specific pixels; enable keep-aspect to avoid stretching.
Common sizes
- 1920×1080 for full-width blog heroes
- 1080 on the long edge for social feeds
- Use Social crop presets when you need a fixed ratio
