Resize an image to exact dimensions
Change an image's dimensions in your browser. No account, no size cap, no watermark.
Preview only. This tool (image-resize) is not functional yet — the in-browser engine is built in a later milestone.
How to resize image
- Add your image. Drop in a PNG, JPG or WebP file or pick one from your device.
- Enter a target size. Type a new width and/or height. Keep the aspect ratio locked to avoid distortion.
- Download. Save the resized image. Nothing is stored after you close the tab.
Frequently asked questions
- Does resizing upload my file anywhere?
- No. The image is resized locally in your browser and is never sent to a server.
- Can I keep the aspect ratio?
- Yes. Lock the aspect ratio and set just one dimension — the other is calculated for you.
- Is there a limit on output size?
- No artificial limit. Output dimensions are constrained only by your device's memory.
