Questions
Is it really free?โผ
Yes. There is no fee, no account, no API key and no usage limit. The only condition is that you keep the small credit line that comes with the snippet.
Will it slow my page down?โผ
The snippet uses loading="lazy", so the widget is only fetched when a reader scrolls near it. Nothing loads on your page until then, and the tool runs in its own frame, so it cannot block your own scripts or styles.
Do my visitors' files get uploaded anywhere?โผ
For most tools, no. PDF, image and calculator widgets do all their work inside the visitor's own browser, so files never leave their device. Tools that fetch something from the internet, such as the video downloaders and currency rates, are the exception.
Can I change the size?โผ
Yes. Pick one of the height presets above, or edit the height and max-width values in the snippet to match your layout. The widget is responsive and fills whatever width you give it.
Can I remove the credit line?โผ
Please don't โ it is the only thing we ask for in exchange, and it is what keeps these widgets free for everyone. You are welcome to restyle it to match your typography.
Will the widget keep working?โผ
The widget always loads the current version of the tool, so fixes and new features appear in your page automatically without you changing anything.
