How to resize an image

1. Upload your image

   Drop the file into the Image field. Any format Sharp can read works — JPEG, PNG, WebP, HEIC, AVIF, GIF, etc.

2. Set the target Width

   "Width (px)" is required: the new width in pixels (1–8000). Aspect ratio is preserved when Height is left at 0.

3. Optional Height

   "Height (0 = auto)" defaults to 0, meaning "compute height to keep aspect ratio." Set a positive value to fit inside W×H (the tool uses fit: inside).

4. Press Run

   Output is a JPEG at quality 90 sized to fit your target box. withoutEnlargement is on — images smaller than the target stay at their original size rather than upscaling and going blurry.
