Gizmetto

Gizmetto is a growing set of free tools that open instantly in your browser, with no app, no account and no uploads.

Check your speakers and headphones, find the note you're singing, tune a guitar or ukulele, measure noise in decibels, test a new monitor for dead pixels and backlight bleed, check a controller for stick drift, strip location data from a photo, or convert a JPEG XL file.

Everything is processed on your own device, and each tool page explains how to read the results. I'm Nabeel and I build and maintain every tool myself, so feedback and tool requests are very welcome.
