Image conversion
Convert between common formats including JPEG, PNG, WebP, TIFF, and BMP using a local ImageMagick engine.
Windows desktop app · Pre-release testingLocal files.
Your files belong on your device
Local files.
Local conversion.
NexusConvert converts images, audio, and video on your computer—not through an online file-conversion service.
Internet access is required for initial license activation. After successful activation, file conversions can run offline. No public purchase or download is available on this page yet.
One desktop workflow
Drop files. Choose a format. Convert locally.
Audio and video
Convert supported media formats and extract audio from videos using a local FFmpeg engine.
A simpler file queue
Select multiple compatible files, choose a shared output format, and process them sequentially with per-file results.
Converted files are saved in a Converted folder beside their source files. Supported conversions depend on the input file and bundled engines. Image conversion uses the first frame; PDF output depends on ImageMagick configuration.
How it works
A focused, three-step process.
Select your files
Drag supported files into the desktop app or use the file picker.
Choose an output
The app offers output formats based on the selected file types.
Convert on your device
Local conversion engines process your files and save the outputs without replacing the originals.
A clear privacy boundary
Local conversion, online activation.
NexusConvert is designed to process source files locally. Its conversion workflow does not upload those files to an online conversion service.
Initial license activation contacts Lemon Squeezy to verify your key and register an installation. The app saves activation information, including the license key, in your operating-system user-data directory so that later launches can check activation locally.
This website is a product-information page, not a browser-based converter. It contains no file-upload form, analytics scripts, signup form, or checkout. Cloudflare hosts the page and may process request information to deliver and secure it.
Local processing is not a guarantee against every security risk. Keep your operating system and the application updated, and use care when opening untrusted files.
Current availability
In development. Not on sale yet.
The Windows application is in pre-release testing. License activation has been tested, and installation, offline operation, and conversion behavior are being checked before release.
Commercial availability is pending storefront approval and completion of release testing. There is no confirmed launch date or public download on this page.
The project is built with Electron and Node.js, with FFmpeg and ImageMagick for local conversion. A verified macOS release is not currently available.
Questions before launch
Is this an online converter?
No. NexusConvert is a desktop application. This page introduces the product; it does not convert files in your browser.
Does the app need internet access?
Initial license activation requires a connection to the license service. After activation is saved successfully, the current design supports offline conversion and local activation checks.
Can I buy or download it now?
Not from this page. Purchase and download information will be added after storefront approval and release testing.
Does it convert every file type?
No. The initial scope is supported images, audio, and video. Office-document conversion is not included, and not every input/output combination is supported.
