Multiple Images to WebP Converter

Take a mixed set of images in any supported format and convert them all to WebP.

How to use the Multiple Images to WebP Converter

  1. Add images in any mix of formats.
  2. Set the quality if you want to.
  3. Press Convert, then download everything as a ZIP.

One output format for a mixed set

Unlike the format-specific batch tools, this one accepts JPG, PNG, WebP, AVIF, BMP, GIF and SVG together and writes every one of them out as WebP. It is the quickest way to standardise a folder that grew organically.

Why standardise a format?

  • Build pipelines and CMS uploads behave more predictably with one format.
  • A single format makes it easy to reason about quality and file size across a project.
  • WebP in particular: smaller files than JPG or PNG at similar quality, with transparency support.

What to watch for

Transparency is preserved. Dimensions are never changed by conversion. Very large batches are processed one file at a time, so allow some time for big jobs.

Frequently asked questions

Can I mix input formats?
Yes. Any combination of supported formats can be added in the same batch.
Is the quality slider used for every format?
It applies when the output format is lossy. For PNG output it has no effect, because PNG is lossless.
