A guided tour of Tooloogle's most-loved free utilities — for professionals, developers, students, and small businesses.
In today's fast-paced world, we're often faced with everyday tasks that can be made dramatically easier with the right tool at hand. That's where Tooloogle comes in. With its growing library of free online utility tools, Tooloogle is the go-to resource for professionals, developers, businesses, and students looking to simplify their workflows. Let's tour some of the most popular tools and see how they can save you time every day.
Buying or selling gold jewellery? The Gold Purity Calculator turns the karat rating stamped on your jewellery into a clear purity percentage and the actual pure-gold weight in grams, ounces, and troy ounces. Make informed decisions before you buy, sell, or insure.
Security starts with strong, unique passwords. Tooloogle's password generator creates cryptographically random passwords with adjustable length, character classes, and exclusion of confusing characters — and runs entirely in your browser, so the password never touches a server.
Developers need globally unique identifiers for database keys, distributed systems, and event tracing. The UUID Generator produces v4 IDs in bulk with format options (with or without hyphens, upper or lower case, with braces) — perfect for seeding tests or onboarding new services.
Inspecting an embedded image from CSS, an email, or an API payload? Paste the Base64 string and instantly preview the image, then download it as PNG, JPG, GIF, or WebP — without the data ever leaving your machine.
Designers and developers constantly translate between HEX and RGB color values. Two-way conversion with a live preview swatch and copy-ready CSS makes the round-trip painless.
Travelling somewhere with a different temperature scale? Cooking from an international recipe? Convert between Celsius, Fahrenheit, Kelvin, and Rankine with full precision and a quick-reference table for common temperatures.
