About ToolByte

Built for real work, not demos

ToolByte started from a simple need: everyday web utilities should be fast, in one place and trustworthy. Instead of a dozen bookmarks and ad-cluttered sites, you get one toolkit where every tool works the same way. These are the same tools we use daily at Duo Dev Technologies.

  • Privacy first

    Code, text and generator tools run entirely in your browser. PDF and image uploads are processed and then deleted automatically. Your files are not kept.

  • Production-grade output

    Minifiers follow industry compression rules, converters handle edge cases and generators produce standards-compliant results.

  • Fast and free, always

    No accounts, no trials, no usage caps and no watermarks. Open a tool and get going.
