Image Resizer
Resize JPG, PNG and WebP to exact pixel dimensions. Keep the aspect ratio, preview your image and download a new copy without uploading it.
JPG, PNG or WebP · Up to 20 MB and 32 megapixels.
Download imageSet exact pixel dimensions
Choose an image and enter a width or height. With aspect ratio locked, the other dimension updates automatically. Unlock it only when stretching the image is intentional. The tool does not crop your photo.
Choose the output format
JPG works well for photographs; transparent areas become white. PNG preserves transparency and sharp graphics. WebP often produces a smaller image for websites. Output is limited to 8192 pixels per side and 20 megapixels in total.
Resizing is not restoration
Making an image larger adds pixels, not lost detail. For crisp results, start with a sufficiently large original. This tool redraws pixels and does not preserve EXIF metadata or animation.
Check the new copy
The original stays untouched. Preview the resized image, download it, and check its dimensions before replacing the original in your project. All image processing happens in your browser.
