UtilYard — Free Online Tools
Free tools for everyday tasks. Everything runs right in your browser.
58 free tools covering developer utilities, text processing, finance calculators, and image tools — plus in-depth guides explaining the concepts behind each one. No login, no uploads, no data sent to a server.
WHY UTILYARD
Most "free tool" sites bury a simple calculation behind ad interstitials, forced sign-ups, or an upload step that sends your data to a server you don't control. UtilYard is the opposite: every tool on this site runs entirely in your browser using JavaScript, so nothing you type, paste, or upload ever leaves your device. There's no account to create, no email to hand over, and no artificial limit on how many times you can use a tool in a day. Open a tool, use it, close the tab — that's the whole interaction model.
JSON formatting, Base64 encoding, UUID generation, regex testing, hash generation, and other everyday utilities developers reach for while debugging, writing scripts, or reviewing someone else's code.
Word counting, case conversion, whitespace cleanup, diff checking, and other text manipulation tools for writers, editors, and anyone cleaning up copy-pasted content.
Mortgage, compound interest, tax bracket, and retirement calculators for anyone budgeting, comparing loan offers, or planning years ahead — built to show the math, not just a final number.
Resize, compress, and convert images between formats like WebP and PNG, plus tools for reading EXIF metadata, picking colors, and generating favicons — all processed locally, not uploaded anywhere.
HOW IT WORKS
Browse by category or search by name — every tool listed below is live and free to use immediately.
Type, paste, or upload directly on the page. Processing happens client-side in JavaScript, so results appear instantly with no server round-trip.
No account, no export limits, no watermark. Copy the output and close the tab whenever you're done.
PRIVACY BY DEFAULT
Because every tool runs client-side, UtilYard has no backend that stores or even sees the data you paste in — there's no database of user input to worry about leaking. The site uses Google Analytics for anonymous traffic stats and may show ads via Google AdSense, both described in the Privacy Policy, but neither has access to what you type into a tool.
