Add the images you want to resize.
Enter a target width and height, or a scale percentage.
Keep the aspect ratio locked to avoid distortion, then download your results.
Shrinking an image in one step makes it soft and aliased. This tool halves the image repeatedly until it is close to the target, then does a final precise pass — the same approach high-end editors use, and a visible improvement on detailed photos.
Apply one set of dimensions to hundreds of files at once. Mixed portrait and landscape images can be fitted inside a bounding box so nothing is cropped or stretched.
Making an image smaller always discards pixels, but the multi-step algorithm here preserves far more detail than a naive single-pass resize. Making an image larger cannot invent detail — use the Upscale tool for that, which reconstructs it with a neural network.
Yes. Unlock the ratio toggle and set width and height independently. The preview shows the distortion so you can judge whether it is acceptable.
Yes. Every frame is resized and the animation timing is preserved.
