How to resize an image
- Upload your image by dropping it or clicking to browse.
- Type the desired width or height — the other updates automatically when the ratio is locked.
- Or pick a preset like Instagram (1080×1080) or HD (1920×1080).
- Choose your output format and click Download.
All processing happens in your browser — your image is never sent to any server. The aspect ratio lock prevents accidental stretching. To resize to a non-proportional size, unlock the ratio first.
