Why choose WebP?
A transparent WebP can be useful for web graphics and photos with cutouts. Local conversion keeps your source artwork private.
What changes in this conversion?
This browser encoder produces a lossy WebP. It is not a lossless archival replacement for PNG. Animated PNG is not supported.
How to convert PNG to WebP
- Choose a still PNG file with the file picker, or drag it into the workspace.
- Select WebP as your output format. Check fine edges and text after downloading. Keep your original PNG when exact pixels are important.
- 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.
