What you can do here
These pages are the English version of OutilsPulse, aimed at searches from the United States. Open a full-screen white background, translate Morse code, convert HEIC, WebP, or AVIF photos to JPG, time your click speed, check a keyboard, estimate a sound level, or generate fancy text you can paste into a bio.
Nothing on this site asks you to install an app. Image conversion and the keyboard test happen locally. The decibel meter uses your microphone only while you leave it running, and it does not record a file.
The French site has more tools
The French site at the same domain also has a webcam test, a microphone test, a screen and dead-pixel test, image compression, cropping, and other utilities. Those pages are still in French. This English section only covers the tools listed above, each with its own address.
