About Batch image resize & rename

Batch Image Resizer and Renamer fits a whole set of images inside width and height limits, renames them from a pattern you define, and hands back a single ZIP.

Runs entirely in your browser. Your files never leave your device.

How to use it

1.Pick the whole set and check the thumbnail order, because that is the order the numbering follows.
2.Set the maximum width and height, pick PNG, JPEG, or WebP, and write the name pattern.
3.Build the ZIP, open a few results at full size, and check the names before you touch the source folder.

Options

Maximum width and height scale images down and keep their aspect ratio. Nothing is enlarged.
The pattern takes the original name and a padded number, and a clash gets a suffix rather than overwriting.

Limitations

Scaling down cannot restore detail a small or heavily compressed source never had.
A ZIP has to be opened before you can look at what is inside it.

Common questions

Will small images be enlarged to the maximum?

No. Anything already inside both limits keeps its own dimensions.

What if two files end up with the same name?

The second one gets a number added. Nothing is silently overwritten inside the ZIP.
