About WEBP
WEBP is typically 25–35% smaller than JPG at the same visual quality, supports transparency, and works in every current browser.
Nothing is uploaded
Other png to webp converters send your files to a server, convert them there, and send them back — leaving a copy on a machine you do not control. This one uses your browser's own image engine, so the file never leaves your device. No account, no queue, no size cap, no watermark.
Questions
How do I convert PNG to WEBP?
Drop your PNG files onto the panel above, check the output is set to WEBP, and press the button. The conversion happens in this browser tab, so nothing is uploaded and there is no waiting for a server.
Is it free, and is there a limit?
Free, with no account and no file count or size limit. Because your own device does the work, there is nothing for anyone to meter.
Are my PNG files uploaded anywhere?
No. There is no server involved. Load this page, disconnect from the internet, and the converter still works — which is the simplest proof that your files are not going anywhere.
Will converting PNG to WEBP lose quality?
WEBP re-compresses the image, so some data is discarded. At high quality settings this is invisible in normal viewing. Work from your originals rather than converting the same file repeatedly.
Can I convert a whole folder at once?
Yes. Add as many files as you like — they are processed one at a time to keep memory use low, and you get a single zip at the end.
