Resize images online, free and private
Change the width and height of JPG, PNG and WebP images right in your browser. Nothing is installed and nothing is uploaded — everything runs on your device. Resize one photo or a batch, keep the aspect ratio locked, and download individually or as a ZIP.
How to resize an image
- Upload your image. Drag files onto the area, or click to browse. The first image’s size is filled in.
- Choose how to resize. Set exact width/height in pixels, or switch to percentage to scale by a factor.
- Resize & download. Save each image, or download the batch as a ZIP.
By pixels vs. by percentage
By pixels is best for an exact size (e.g. a 1200×630 banner). By percentage is best to make everything smaller or larger by the same factor.
