Good to know
How these tools work
Honest readings
Levels are shown in dBFS, relative to your device, not as calibrated sound pressure. The webcam test reports what the browser negotiated, which can be less than the camera supports.
Nothing is uploaded
Audio and video are analysed and recorded in the tab. Recordings stay in memory until you download them.
Questions
Frequently asked questions
Why can't the site hear my microphone?+
Check that the browser has permission, that the right input is selected, and that no other app is using it. Mic Test names the error the browser reports and how to fix it.
Is my webcam recording uploaded?+
No. Webcam Recorder keeps each take in the tab's memory and saves it only when you download it. Closing the tab discards it.
Can these tools measure loudness in decibels?+
They show levels in dBFS, relative to the loudest signal your device can capture. That helps when setting levels, but it is not a calibrated sound level meter.

Other categories
Everything runs in your browser, so a signed contract never leaves your computer. Most of these take files up to 75 MB and 500 pages.
Business
Invoices, receipts and quotes print to an A4 PDF straight from the page. The CV maker and Kanban board save as you go, in this browser rather than an account.
Documents
Draw a signature with a mouse, trackpad or finger, or type one, then download it as a transparent PNG, an SVG or a JPG.
Writing and text
Counters for words, characters, syllables and reading time, a text diff, a notepad that saves locally, and a typing test that compares you with the last hour of results.
Images
Nine of these send the image to our server, where it is converted in memory and not kept. The other eight, including HEIC to JPG and the cropper, never upload anything.
Finance
Loans, mortgages, take-home pay, sales tax, tips, a monthly budget and a splitter for shared costs. The budget and the group ledgers are saved in this browser.
Calculators
The biggest section: dates, ages, grades, units, sleep cycles, dice and timers, plus a scientific calculator that handles complex numbers and solves equations.
Developer
JSON, regex, hashes, UUIDs, JWTs and subnets, plus tests for your keyboard, click speed, dead pixels and refresh rate.
Music
A metronome with swing and accents, a pitch pipe, tap tempo, the circle of fifths, and a transposer that reads ChordPro chord sheets.
Crypto
Profit and loss, DCA, staking, gas fees and liquidation prices. Nothing connects to a wallet or a price feed; you type the numbers in.
