FAQ

Bulk image resizer — FAQ

How many images can I resize at once?

There is no fixed limit. Very large batches depend on your device’s memory, so for hundreds of big photos work in groups.

Will each image keep its proportions?

Yes, with “Keep aspect ratio” on, only the width is fixed and each image’s height is calculated from its own shape.

Can I compress all images to a target KB?

Yes. Set a target size in KB and every image is compressed to fit.

Are my images uploaded?

No. All resizing happens in your browser.
