Toolio bundles 195 free, browser-based tools into one fast, private site. For developers: 32 utilities — JSON/XML/SQL formatters, Base64, JWT, hashing, a regex tester, plus color and text tools. Alongside them: a full PDF suite (merge, split, compress, sign, convert), image tools (background removal, HEIC/format conversion, compression), media tools (video-to-GIF, audio) and 29 calculators. Most tools run entirely client-side, so your files are never uploaded — the few that need a server are clearly labeled. No account, no watermarks, no limits, free, in 16 languages. Made by Pong Studio.
