Titan Converter's Archive and 3D Model Tools, Explained

Two Tools, One Shared Idea

Archive & Compression and the 3D Model Converter are two of the newer additions to Titan Converter, and they cover ground the other tools don't touch: opening and rebuilding compressed folders, and moving 3D models between the formats different software expects. Both currently run server-side in the browser tool rather than the offline desktop app, which is the one meaningful difference from the rest of Titan Converter's feature set.

They're grouped together here because they solve the same basic kind of problem — a file that's in the wrong container for whatever you're trying to do with it next — just for two very different audiences.

ZIP, TAR, 7-Zip and RAR, Handled in the Browser

The Archive tool opens, builds, and converts between ZIP, TAR, TAR.GZ, GZIP, 7-Zip, BZIP2 and XZ archives directly in your browser tab, and it extracts RAR files as well. Converting between formats isn't a simple rename under the hood — it fully unpacks the source archive and repacks every file into the new container format, checking each entry's path before extraction.

Two specific cases run on Titan's server instead of fully in-browser, because the processing involved is too heavy for a browser tab to handle smoothly: creating Zstandard archives, and extracting ISO, CAB, CPIO or LZH files. The tool tells you up front when a file falls into one of those categories, and any file sent to the server for this is deleted as soon as the result is ready.

Moving a Model Between GLB, OBJ, glTF and More

The 3D Model Converter moves a model between GLB, OBJ, glTF, STL, PLY, 3MF and DAE, and it keeps materials attached to the model through the conversion rather than stripping them out. FBX and 3DS files work as input formats, even though they aren't available as conversion targets.

Like the archive tool, 3D model conversion currently runs server-side in the browser rather than in the offline desktop app. Titan Converter's own materials note that offline desktop support for this tool is planned but not yet available, so for now this one specifically requires an internet connection even if you're otherwise using the offline-first parts of Titan for everything else.

Why These Two Aren't in the Desktop App Yet

Most of Titan Converter's tools — general format conversion, frame extraction, images to video, compression — are built around FFmpeg and similar libraries that run efficiently as a local, offline process. Archive handling and 3D model conversion lean on different, heavier tooling that's more straightforward to run server-side for now, which is why Titan flags this as a temporary state rather than a permanent design choice.

If keeping a file completely off any server matters for your situation — a proprietary 3D asset, a sensitive archive — that's worth knowing going in, since it's the one place these two tools diverge from Titan's usual 100% offline default.

Converting a Downloaded Model for 3D Printing

A common real-world case looks like this: you've downloaded or exported a model as an OBJ file, but your slicer software — the program that turns a 3D model into printer instructions — only accepts STL or 3MF. Rather than hunting for a separate desktop conversion tool or a plugin for your 3D software, the 3D Model Converter takes the OBJ directly and outputs a properly formatted STL or 3MF ready to hand to the slicer.

The same pattern applies in the other direction too — an STL scan or download that needs to become a GLB for a web-based product viewer, or a DAE file from older software that a modern game engine won't import directly. The tool doesn't care which direction you're converting; it just needs the source format to be one of the seven it reads.

Using Either Tool

1. Open the Archive or 3D Model tab in the browser-based converter at titanconverter.site.
2. Upload your file — an archive to extract or convert, or a 3D model to convert.
3. Pick your target format from the supported list for that tool.
4. Convert and download the result.

Both tools are free to use within the same daily conversion limits as the rest of the browser-based converter, and neither requires an account or payment to try.
