MyToolster: 50+ Free Online Tools That Run Entirely in Your Browser
Most "free tools" sites are ad farms with a signup wall. MyToolster is the opposite: 50+ utilities that run entirely in your browser. No account, no upload to a server, no watermarks.
What you get
- AI detectors — check whether text or an image was AI-generated
- Background remover — one-click cutouts for product photos
- Audio/video to text — transcription plus SRT subtitle export
- Image tools — compress, convert, resize, crop
- Text tools — case conversion, word counters, formatters, encoders
- Developer tools — JSON formatters, regex testers, encoders/decoders
- Converters — units, currencies, file formats
Why browser-native matters
Your files never leave your machine. That means no upload wait, no privacy fine print, and the tools work offline once loaded. For anything sensitive — client assets, unreleased screenshots — that's the difference between usable and unusable.
Everything is at mytoolster.com, free.
