Image Resizer
Resize photos and screenshots to exact pixels in your browser
Set an exact width and height, keep the aspect ratio locked, and save the result as PNG, JPEG or WebP. The picture is never uploaded.
Everything on this page is processed in your browser. Nothing is uploaded.
What this tool does
Resizing is done with the canvas API that your browser already ships, so the selected picture is read from disk into the page and back out again as a download. Lock the aspect ratio to change one side and let the other follow, or unlock it to force exact dimensions, and pick the output format that suits the destination: PNG for flat graphics, JPEG or WebP with an adjustable quality for photographs.
How to use it
- Choose an image from your device.
- Set the target width and height, and pick an output format.
- Press resize, then download the new file.
Privacy
This tool runs entirely in your browser. Your input is never uploaded, stored or shared — closing the tab removes it.
Frequently asked questions
- Is my image uploaded to a server?
- No. The file is decoded, redrawn and re-encoded inside your browser tab, and the download link points at that in-memory result. Nothing is sent anywhere.
- Will resizing reduce the file size?
- Usually yes, because fewer pixels take fewer bytes. JPEG and WebP also expose a quality slider, which trades detail for a smaller file.
- Can I enlarge a small image?
- You can, but a browser can only interpolate the pixels it has, so upscaling looks softer than the original. Enlarging beyond about twice the original size rarely looks good.
