Toolio by Pong Studio

Toolio bundles 195 free everyday tools into one fast, private site: PDF signing, merging and conversion; image background removal, HEIC and format conversion; video-to-GIF, audio trimming; 29 calculators; 32 developer utilities; and fun generators. Most tools run entirely in your browser, so your files are never uploaded to a server — the few that do need a server are clearly labeled. No account, no watermarks, no limits, free, in 16 languages.
