Image Resizer
Resize multiple images by dimensions or percentage and save the results.
You can select multiple files. These images never leave your browser.
About this tool
Resize JPEG, PNG, and WebP images entirely in your browser. Set dimensions or a percentage, preserve the aspect ratio, process multiple files, and download each result without uploading images to a server.
In dimension mode, locking the aspect ratio automatically updates the other dimension. Percentage mode scales both dimensions by the same amount.
Images stay inside your browser and are never uploaded. To keep processing responsive, images longer than 4,096 pixels are reduced before the requested resize is applied.
Export in the original format, PNG, JPEG, or WebP. JPEG and WebP use 90% quality. Enlarging can soften details, so the tool works best when reducing image size.
FAQ

- Yes. Enable the aspect-ratio lock and the other dimension updates automatically when width or height changes.
- Which image formats are supported?
