This free image resizer lets you change the dimensions of JPG, PNG, and WebP files in seconds — resize a photo for Instagram, shrink a screenshot for an email attachment, or scale a product image down to the exact pixel size a marketplace requires. Nothing is uploaded: the resize happens locally in your browser, so even large personal photos stay on your device.
It works as an online image resizer without watermarks, a quick way to make an image smaller in KB, and a simple photo resizer for social media, resumes, and email. You can lock the aspect ratio so a JPG stays proportional, resize a PNG while keeping the transparency, or convert a heavy PNG to WebP or JPG to cut the file size dramatically. Use the quick 25%, 50%, and 75% buttons for a fast downscale, or type the exact width and height you need.
Under the hood the tool uses the browser's Canvas API with high-quality smoothing, so downscaled images look sharp and clean. Transparent PNGs exported as JPG are placed on a white background automatically, and the quality slider lets you trade a bit of fidelity for a much smaller file when uploading somewhere with a size cap.
