Frequently asked questions

Are there any usage caps on the PNG to WebP Converter?
There is no cost and no cap. The PNG to WebP Converter is not a demo of a paid product, so nothing is held back or watermarked.
Can you see what I put into this utility?
No. The PNG to WebP Converter runs entirely in your browser using JavaScript. Because the work happens locally, the utility also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
What do people use the PNG to WebP Converter for most?
Typical uses: cutting image weight on a website. Keeping transparency while reducing size. Converting a folder of assets in one pass. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Will a big file be rejected?
There is no limit set by us, because your file is never uploaded — the only ceiling is the memory your own browser will give the tab. Very large files simply take longer to process, and a phone will give up sooner than a desktop.
