Frequently Asked Questions

Can I mix different image formats (PNG, JPEG, WebP) in the same batch?

Yes—each image is resized and saved in the format you choose from the output format dropdown.

Why does the lock‑aspect‑ratio option not work with percentage resizing?

When scaling by percentage, both dimensions are multiplied by the same factor, so the aspect ratio is preserved automatically. The lock is only relevant when you enter explicit pixel values.
