Why choose WebP?
WebP is useful for web delivery and can reduce the size of photographic images, depending on content and quality.
What changes in this conversion?
File size is not guaranteed to shrink. Re-encoding an already compressed JPEG is another lossy step. Older software may prefer JPEG.
How to convert JPG to WebP
- Choose a still JPG file with the file picker, or drag it into the workspace.
- Select WebP as your output format. Resize to the dimensions your page actually needs. This often saves more space than changing the format alone.
- Choose Convert, then download your file. For a batch, Download ZIP collects successful results.
Limits and browser compatibility
Still images use native decoding and encoding where supported, with a local WebP encoder fallback. Output is 8-bit sRGB; original metadata, HDR range and wide-gamut precision are not archived. Standard inputs are capped at 100 MB, 50 MP on desktop and 16 MP on mobile or low-memory devices, subject to memory limits.
Does my file leave my device?
No. The worker reads your file locally and creates your download in browser memory. Original metadata is always removed. The output uses 8-bit sRGB pixels.
Can I convert a batch?
Yes. Select up to 24 files within the 256 MB batch limit. Each file is processed separately, so a failed image does not prevent the others from completing.
