Need to resize an image to exact pixel dimensions? Our free online image resizer lets you upload any photo or graphic, set a custom width and height, and optionally lock the aspect ratio so your image never distorts. Choose between PNG, JPEG, or WebP output, adjust compression quality, and download your resized image in seconds — all processed locally in your browser.
No. The entire resize operation happens in your browser using the HTML5 Canvas API. Your image never leaves your device, so your files stay completely private.
When locked, changing the width automatically recalculates the height (and vice versa) to preserve the original proportions of your image, preventing stretching or squishing.
Use PNG for graphics, screenshots, or images with transparency where you need lossless quality. Choose JPEG for photos where a smaller file size matters. WebP gives the best compression for modern web use.
The tool supports dimensions up to 20,000 × 20,000 pixels. Very large canvases depend on your browser and device memory, but typical web and print sizes work without issue.
