Resize images while maintaining aspect ratio
Resize images while maintaining quality and aspect ratio
Supports JPG, PNG, GIF, WebP formats. Select multiple files to resize them as a batch.
The resize options above apply to every file in the batch.
Select several files at once in the picker and the tool switches to a batch queue listing every image. Set the width, height, and quality once, because the same settings apply to each file, then click Resize All Files. Every row shows its own status, moving from queued through an animated processing indicator to done or error, along with the result dimensions and size.
After a batch finishes, Download All as ZIP bundles every successful result into one archive. Each finished row also keeps its own download link, and duplicate names are numbered automatically inside the archive so nothing overwrites anything else.
It is on by default and links the width and height fields, so changing one recalculates the other from the proportions of your image. In batch mode it goes further: every picture is resized to the shared target width, with each height computed from the individual aspect ratio so nothing gets stretched.
One-click presets fill in 800x600, 1024x768, 1920x1080, or 500x500, and any custom values up to 4000 pixels can be typed directly. The quality slider, ranging from 10 to 100, controls how aggressively the JPEG output is encoded, with lower values producing smaller files.
No. Every resize and even the ZIP packaging happen locally in your browser, so none of the selected files ever leave your machine.
