Frequently Asked Questions
Can I resize many images at once?
Yes — add as many images as you like, set a target width, height, or percentage, and every file is resized with the same settings. Download the whole batch together as a single ZIP.
Will bulk resizing keep the aspect ratio?
By default each image is scaled proportionally so nothing looks stretched. You can resize by percentage to shrink everything uniformly, or set a fixed dimension to standardize a set.
Is there a limit or an upload?
There's no upload — every image is processed locally in your browser, so the practical limit is just your device's memory. Large batches stay completely private.
