FAQ
Does this WebP converter upload my images?
No. Conversion runs locally in your browser; files aren’t sent to a server.
Can I convert WebP to PNG or JPG?
Yes—choose PNG or JPG as the output format, then convert your WebP file.
What does the quality slider do?
It controls compression for WebP and JPG (lower = smaller file, more artifacts). PNG ignores quality.
Why does JPG lose transparency?
JPG doesn’t support alpha; enable “Flatten to background” to fill transparent areas with a color.
Why might conversion fail in some browsers?
If the browser can’t encode the selected output format, it may return a null blob; try another format or a newer browser.
Is there a size limit?
Very large images can exceed memory on mobile; if you hit errors, resize first using the related resize tool.
Can I batch convert multiple images at once?
Yes—select multiple files and the tool will convert them in a single run.
