Frequently asked questions

Do I need an account to use the JPG to WebP Converter?
No charge and no sign-up. There is no free tier to run out of because there is no paid tier — inputtesthub.com is funded by advertising rather than by metering the tool.
Is the JPG to WebP Converter safe to use with private information?
No. The JPG to WebP Converter runs entirely in your browser using JavaScript. Your input never reaches inputtesthub.com or any third party — open your browser's Network tab while you use it and you will see no request go out.
What problem does the JPG to WebP Converter solve?
In practice it gets used for three things: speeding up a photo-heavy page. Meeting a Core Web Vitals image budget. Converting a product photo library. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
How large a file can I use?
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.
