What is Image Resizer?
Change the size of one or many images by entering a width, a height or both, in pixels. Proportions are always kept, so nothing gets stretched: with both values, each image is scaled to fit inside that box. Compare the original and the result side by side before you download, then save a single file or a ZIP. Each image keeps its own format. Everything runs in your browser, so your images are never uploaded.

Frequently asked questions
Common questions about Image Resizer.
Just enter a width, a height or both. The aspect ratio is always kept: with one value, the other side follows the image's shape, and with both, the image is scaled to fit inside that box without being distorted.
Yes. Add up to 30 images and they are all resized with the same width and height. Download them one by one or as a single ZIP.
Yes. Enlarging cannot add detail that was never there, so images look softer when scaled up. For the sharpest result, resize to a size equal to or smaller than the original.
Usually, yes. Fewer pixels generally means a smaller file. The preview shows the file size before and after so you can check.
Each image keeps its own format: JPG stays JPG, PNG stays PNG and WebP stays WebP. BMP files are saved as PNG. Transparent areas turn white in JPG.
No. Images are resized in your browser using the Canvas API and never sent to a server.
