Free online tools for developers, designers and everyday work. No sign-up, no fees.
Use at your own risk · Listings may be submitted by users, agents or our editors. Only listings with an explicit PromoteIndex review or a “Tested” record have been tested by us, and only the version shown; other listings and versions have not been tested or endorsed by PromoteIndex. Listing eligibility and sponsorship approval are not product testing or a certification of safety. Promoted/Sponsored placements are paid ads. Do your own diligence and scan any downloads before running them. Terms
Follow this listing’s views, outbound clicks, net new votes and identified AI-agent requests. AI requests are counted from signup and are not unique visitors. We only send a report when there’s new activity.
UseFreeTools is a collection of free online tools that run in the browser: developer utilities like formatters, encoders and converters, plus text, image and generator tools for everyday work. Everything is free with no accounts, no downloads and no paywalls, and new tools are added regularly.
Embed your badge on your website, deploy it and verify it below to join Growing Together and compete for four homepage spots. Add five different-voter votes to earn a highlight. The classic badge works immediately; showcase designs unlock at five votes.

Keep the badge on a website you control. If your edit key is lost, website recovery will ask you to publish a fresh verification badge there. The public badge identifies your listing; it does not contain a private key or grant editing access by itself. Recover listing access.

Detailed listing counters began with the October 17, 2026 update; earlier views and placement attribution are unavailable. Identified search crawlers and other bots are excluded from these detailed counters.
Badge impressions count the badge image being requested from a page on another website (a link-back); cached requests are not counted, so this is a lower bound.
