Why Use a Bulk Resizer?
Preparing a photo set for a website, listing or archive means giving every image the same dimensions, and doing that one file at a time is painful. Bulk resize applies a single width and height across the entire batch — JPG, PNG, WebP and even iPhone HEIC input — and packs the finished set into one ZIP download. Choose JPG, PNG or WebP output and adjust the quality slider to control size. All resizing happens locally in your browser, so your photos never leave your device.

Resize dozens or hundreds of images with one setting.

Frequently Asked Questions
Everything you need to know about bulk image resizer.
As many as your browser can hold in memory — typically hundreds of normal photos.
Yes. Enter only a width or only a height and the other value is calculated automatically.
No. Bulk resizing runs entirely in your browser.
Common image formats work — JPG, PNG, WebP, GIF, BMP and even iPhone HEIC photos. You can output the batch as JPG, PNG or WebP.
Every image gets the same settings. If you enter only one dimension, each photo keeps its own aspect ratio, so the other side can differ across mixed orientations.
