Image Resizer
Set a target width or height (aspect ratio stays locked unless you unlock it) or scale by percentage, then download the resized image in its original format or a new one. Resizing uses high-quality browser resampling and happens entirely on your device.

Frequently asked questions
Are my files uploaded to a server?
No. This tool runs entirely in your browser using local processing — your files never leave your device, which also makes conversion instant with no upload wait.
Will resizing blur my image?
Downscaling uses your browser's high-quality resampling and generally looks crisp. Upscaling cannot invent detail — a small image enlarged a lot will soften, as with any resizer.
Is this tool really free?
Yes — completely free, with no account, no watermarks and no file limits beyond what your device's memory can handle.
