What NanoPix does
NanoPix helps people trim videos, merge clips, convert formats, compress files, crop media, extract audio, make GIFs, inspect codecs, and complete other everyday media jobs directly in a modern browser.
Browser-local media toolkit
NanoPix builds private media tools that run in your browser.
NanoPix is a local-first toolkit for practical video, audio, and image editing. The core idea is simple: common media tasks should not require uploading private files to a remote server.
Privacy model
NanoPix loads the web app and local processing engine, then reads selected files inside the browser session. Editing and export work is handled on the user device with browser technologies such as WebAssembly, WebCodecs, MediaInfo, and Web APIs. The source media does not need to be uploaded to NanoPix servers for editing.
Editorial standards
NanoPix guides are written around real tool workflows: what to choose, what can fail, how browser-local processing differs from cloud upload tools, and where device limits matter. Articles are updated when tools, browser behavior, or recommended workflows change.

Technology principles
- Local-first processing for private files whenever the browser can handle the job.
- Clear trade-offs instead of pretending browser tools have no memory or performance limits.
- Practical output formats such as MP4 H.264 + AAC for broad compatibility.
- No watermark and no account requirement for core utility workflows.
- Guides that explain both the tool steps and the privacy boundary.
