What does this tool do?
Scale a batch of images (max width, fixed width, max height or percent), rotate 90°/180° and flip horizontally or vertically, then export as JPG, PNG or WebP. Great for unifying avatar sizes, shrinking ultra-wide shots and fixing tilted photos. All local.
FAQ
Why did my image get bigger with a maximum width?
It cannot. “Max width” is a ceiling, not a target — an image smaller than the limit keeps its original size and is never upscaled. If you do want to enlarge, switch to the fixed-width or percentage mode.
Why does my transparent PNG get a black background when exported as JPG?
JPG has no alpha channel, so transparent areas are filled with the background colour, black by default. There is a dedicated background colour field for JPG output — or keep exporting PNG or WebP to preserve transparency.
Which formats are supported, and can I batch?
JPG, PNG, WebP plus anything your browser can decode such as HEIC and AVIF. Select many at once and collect the results with “Download all (ZIP)”.
How do I fix a batch of crooked photos?
Use the rotation control to turn a whole batch 90° or 180°. If the photo carries EXIF orientation data, the browser usually applies it automatically while decoding. Rotation applies to the entire batch, so split files that face different directions.
Are my images uploaded?
No. Scaling, rotation and export all run locally in your browser; the original files never leave your device.
