Frequently asked questions
Can I convert while compressing WebP?
Yes — change Output format in Custom settings to JPEG or PNG, or use a Convert hub page. Default output here stays WebP for smaller web assets.
What is the default output format?
WebP. The tool shrinks file weight while keeping the modern WebP container unless you change format in settings.
What if the file still exceeds my target?
Reduce max width, lower quality, or open a dedicated size page like 500KB or 1MB. Use Compare to confirm sharpness, or Adjust to re-run that image with tighter settings.
Batch compress WebP with ZIP download?
Yes. Add multiple images, set a target size, process in the browser with no upload wait, then download individually or as a ZIP.
