How it works
Upload your PNG files
Drop in one file or a whole batch — dimensions and file size show up instantly.
Set quality & size
Adjust WebP quality and resize if you want — transparency is kept automatically.
Download
Grab a single WebP directly, or select multiple and download them together as a ZIP.
Smaller files, same transparency
Batch conversion
Add any number of .png files and convert them all in one pass.
Dramatic size reduction
WebP typically produces a noticeably smaller file than PNG for the same image.
Adjustable quality
Balance file size and image quality with a simple slider, applied to every file.
Transparency preserved
WebP has its own alpha channel, so any transparent areas in your PNG carry straight through.
Optional resizing
Keep the original resolution, scale down by a percentage, or cap output to a maximum width.
Runs entirely on-device
Every file is read and converted locally in your browser. Nothing is ever uploaded or stored anywhere.
Frequently asked questions
Why convert PNG to WebP?
WebP typically produces a much smaller file than PNG for the same image, which means faster page loads and less storage — while still supporting transparency.
Does WebP support transparency like PNG?
Yes. WebP has its own alpha channel, so any transparent areas in your PNG carry over to the converted file.
Can I convert multiple PNG files at once?
Yes. Add as many .png files as you like, convert them together, and download each WebP individually or grab them all at once as a ZIP.
Will I lose quality converting PNG to WebP?
At high quality settings the difference is barely noticeable, but WebP encoding here is lossy, so there is some trade-off. Use the quality slider to keep more detail or shrink the file further.
Will this work in any browser?
Most current browsers can encode WebP, but a few older or less common ones can't. If a file can't be converted, it will be flagged so you know to try a different browser.
Is my file uploaded to a server?
No. Every PNG file is read and converted locally in your browser. Nothing is ever uploaded, transmitted, or stored anywhere.
