Private Image Resizer and Compressor

Image Resizer is a fast, privacy-focused tool for resizing and compressing images online. It works directly in your browser, so selected files are processed locally instead of being uploaded to a remote server.

You can resize images by exact width and height, keep the original aspect ratio, convert between JPEG, PNG, and WebP, compress images toward a target file size, and process multiple files in batch mode. It is useful for profile pictures, forms, social posts, banners, document uploads, signatures, screenshots, and everyday image cleanup.

The project also includes companion tools for Chrome, Firefox, Obsidian, and Android, so you can resize images in the workflow where you already keep them.
