How to resize an image

  1. Upload your image by dropping it or clicking to browse.
  2. Type the desired width or height — the other updates automatically when the ratio is locked.
  3. Or pick a preset like Instagram (1080×1080) or HD (1920×1080).
  4. 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.
