Resize images by pixels or percentage
This image resizer runs entirely in your browser. Drop PNG, JPEG, WebP, GIF, or SVG files — or import SVG from code — then set a target size or scale percentage and download resized copies without uploading anything to a server.
Use size mode when you need exact output dimensions. Click the link between width and height to lock or unlock aspect ratio — locked keeps proportions when either side changes. Use percent mode to scale every image by the same factor, which is useful for thumbnails or retina exports.
Batch export
Export one file or a ZIP archive named resized-images.zip.
Export format and file size
Choose PNG, JPEG, WebP, GIF, or keep the original format. Quality defaults to 90%. Leave target size empty for automatic encoding, or set a kilobyte limit to compress for web or email. Processing stays local.
