Myriadfile is a set of file tools that run entirely in your web browser. It is made by {{OWNER_NAME}}, an independent developer in {{CITY_COUNTRY}}.
Why Myriadfile exists
Converting a photo or fixing a subtitle file should not require handing it to a stranger’s server. Yet most online converters do exactly that: your file is uploaded, processed somewhere else, and you are asked to trust that it is deleted afterwards. For holiday photos that is uncomfortable. For passport scans, mark sheets and signatures it is a real risk.
Modern browsers can decode and encode images, play and capture video, and run complex code at near-native speed. Myriadfile puts those abilities to work so the file never has to leave your device. You can check this yourself: open your browser’s developer tools, switch to the Network tab, and convert a file. You will see the page and its libraries load, and nothing being sent back.
What we promise
- No uploads. Files are processed in your browser. We have no server-side storage for them, because they never reach us.
- No accounts, no watermarks, no limits. Every tool is free to use as often as you like.
- Honest limits. When a tool cannot do something well, such as recording video faster than real time or keeping text selectable after compressing a PDF, the page says so.
- Verified presets. Exam and passport presets are published only after checking the official notice, with the source and verification date shown.
How the site is funded
Myriadfile shows ads from Google AdSense. Ads pay for hosting and development so the tools can stay free. Ads are kept away from download buttons, and the privacy policy explains what advertising cookies do and how to control them.
