Images are converted locally in your browser and are never uploaded.
Re-encode AVIF images as WebP for CMS, app, and browser workflows that accept WebP but not AVIF. Conversion runs locally with batch and ZIP support.

Add AVIF files, choose one WebP output profile, then save the completed results. Processing stays in the current browser tab.
Add still AVIF files, select a folder, or drop a group of images into the converter. Each file is decoded in the current browser tab.
Choose a WebP quality value and an optional maximum dimension. Compare the result with the source before replacing a delivery asset.
Download compatible WebP files individually or package every completed conversion in one ZIP archive.
WebP is supported by a broad range of browsers, content management systems, and image pipelines. An AVIF to WebP derivative can help when a platform accepts WebP but rejects AVIF.
AVIF and WebP have different encoders and compression behavior. Compare actual bytes and visible detail in the destination workflow instead of assuming the newer format is always smaller.
Start around quality 80 for photographs, inspect gradients and fine detail at the intended display size, and adjust only when the visual trade-off is clear. Re-encoding a lossy source can expose artifacts.
Resize large sources before export when the destination has a known display width. Dimensions often affect transfer size more than small quality changes.
Choose WebP when a CMS, social platform, email tool, or older browser workflow accepts WebP but not AVIF. Keep the AVIF original so you can generate another derivative later.
WebP output from this page is still-image output. Animation and source metadata are not preserved by the browser canvas conversion path.
Use these differences as a review checklist, then judge the actual downloaded file in its destination.

Practical answers about supported files, privacy, quality, and what the browser-based converter does with your images.
Some CMS, browsers, and delivery platforms accept WebP but not AVIF. A WebP derivative can improve compatibility while the original AVIF remains available.
No. File size depends on image content, dimensions, source quality, and encoder settings. Compare the actual output and visual detail.
No. The browser decodes the source and creates WebP locally; selected image files are not sent to the site.
Yes. Select multiple files or a folder and download successful WebP results individually or as a ZIP.
