NovaGrid is a small, independent collection of everyday file and utility tools that run entirely inside your browser — fast, free, and private by design.
⏚ Nothing is uploaded — your files stay on your device
NovaGrid brings together the kind of small tools people reach for all the time — converting an iPhone photo to JPG, turning a clip into a GIF, pulling the audio out of a video, or making a QR code for a link. Most websites that do these things upload your file to a server, process it there, and send it back. We took the opposite approach: everything happens on your own device.
Free online converters are everywhere, but they usually come with a catch — your private files get uploaded to someone else's server, there are daily limits, watermarks, sign-up walls, or an avalanche of pop-ups. We wanted tools that are genuinely free to use, don't ask for an account, don't watermark your output, and never put your files at risk by sending them anywhere. NovaGrid is our answer: useful tools that respect your privacy and your time.
Modern browsers are powerful. Using WebAssembly — the same kind of technology that lets demanding software run on the web — we compile proven, open-source libraries (such as libheif for HEIC images and ffmpeg for audio and video) so they run directly in your browser tab. When you drop in a file, it is read, converted, and offered back to you for download without ever leaving your computer. That means:
We add and refine tools over time. If there is something you wish NovaGrid did, we would genuinely like to hear about it.
Running and improving these tools takes time and hosting. To keep everything free and without sign-up, NovaGrid shows advertising provided by Google. We keep ads clearly labelled and separate from the tools themselves, and showing ads never requires us to see or store your files — they still stay on your device. For details on cookies and advertising, see our Privacy Policy.
Questions, feedback, bug reports, or ideas for new tools are all welcome. Reach us any time at contact@novagrid.cc or via our contact page.
