How to use it
- 1Select all your images (up to 500) or drop them in.
- 2Set the target size, fit mode and output format.
- 3Choose a filename pattern such as {name}-{w}w or product-{000}.
- 4Click Resize all, then Download all (ZIP).
- You give
- Up to 500 JPG, PNG, WebP, AVIF, GIF or BMP images
- You get
- A ZIP of resized, renamed images
- Good to know
- Files are processed one at a time to keep memory low; expect roughly 0.1–0.5 s per photo depending on size and device. Folders can't be dropped directly in every browser — select the files inside instead.
- Privacy
- Processed on your device. Nothing is uploaded, stored or logged.

FAQ
What filename tokens can I use?
{name} original name, {n} running number, {000} zero-padded number (one zero per digit), {w} and {h} output size and {date} today's date.
What happens with mixed sizes and orientations?
With “Fit inside”, the width and height act as maximums, so portrait and landscape photos are each scaled to fit without distortion.
What if two files end up with the same name?
Duplicates are numbered automatically in the ZIP — photo.jpg, photo (2).jpg — so nothing is overwritten.
