What it does

  • Resize to exact pixels or a percentage, keeping the aspect ratio if you want.
  • Rotate by 90° or 180°, flip horizontally or vertically, and crop.
  • Convert between JPEG, PNG and WebP, choosing the quality.
  • Undo any step, then download the result.

Who it's for

Anyone who needs a quick edit before uploading a photo somewhere, without installing anything or trusting a random website with the file.
