How it works
The resize happens on a canvas in your browser. When an image is reduced by more than half, it is scaled down in several steps, each halving the size, which gives noticeably smoother results than a single jump and avoids jagged edges and moiré patterns.
In Fill mode the image is scaled to cover the new size and the overflow is trimmed equally from both sides, keeping the centre. In Fit mode the whole image is kept and the leftover space is filled with transparency or the background colour you choose.
Useful for
- Making images the exact size a social network expects
- Reducing camera photos to a sensible width for a website
- Creating thumbnails and profile pictures
- Meeting the pixel limits of a form or marketplace listing
Limitations
- Making an image larger than the original cannot add real detail; it will look softer. For better enlargements use the image upscaler.
- Animated GIFs become a single still frame.
- The largest size you can create depends on your device; most browsers handle up to 16,384 pixels on a side.
