ConvertX on Ubuntu 24.04 LTS

ConvertX on Ubuntu 24.04 LTS

ConvertX is a self-hosted online file converter with a clean, modern web interface. You sign in, drag a file into the browser, pick a target format, and ConvertX converts it for you — then lets you download the result or keep a history of past conversions. It supports more than a thousand input and output formats across images, documents, audio, video, e-books, vector graphics and 3D models.

What is included

• ConvertX v0.18.0, the AGPL-3.0 licensed self-hosted core, shipped as the official upstream container pinned by digest
• A large bundle of open-source converters baked into the image: FFmpeg, ImageMagick, GraphicsMagick, Vips, libheif, libjxl, LibreOffice, Calibre, Pandoc, Inkscape, XeLaTeX, resvg, Potrace, VTracer, Assimp and more
• Docker Engine with the ConvertX app and API on the loopback interface behind nginx on port 80
• An embedded SQLite database and a single data volume for uploads and converted files
• A unique account owner and a unique session-signing secret generated per VM on first boot, with open sign-up disabled
• A clean, empty instance on first boot with no default account and no shipped secret
• 24/7 cloudimg support

Secure by default

With stock ConvertX the very first person to reach the page can register the owner account. This image never leaves that open. On first boot, before the port is reachable, a unique owner account is created with a per VM password, the session-signing secret is generated per VM, and open registration and anonymous use are disabled, so the instance cannot be seized. The data volume ships empty, so no files, history or secrets are baked into the image.

Licensing

ConvertX is free and open source under the GNU Affero General Public License v3, shipped unmodified. There is no per seat fee. The cloudimg charge of 0.04 US dollars per vCPU hour covers packaging, security patching, image maintenance and 24/7 support. Recommended size: Standard_B2s. This image is produced by cloudimg and is not affiliated with, endorsed by, or sponsored by ConvertX.
