An OpenIV alternative that runs in your browser
OpenIV is the classic Windows tool for GTA 5 archives, and for editing a live game installation it is still the right tool. But if what you actually need is to open an RPF, look inside a model, export a texture, or build a DLC pack, you can do all of that here with nothing installed: open the RPF browser and drop the archive in.
What each covers
| Task | gtax.dev (browser) | OpenIV (desktop) |
|---|---|---|
| Open and browse RPF archives | Yes, in the browser, nested archives included | Yes |
| Extract files from archives | Yes | Yes |
| Preview models (YDR, YDD, YFT) in 3D | Yes, with textures | Yes |
| View and export textures (YTD) | Yes, with DDS export and thumbnails | Yes |
| Build new RPF and dlc.rpf archives | Yes | Yes |
| Edit files inside a live game install | No, browsers cannot write to your game folder | Yes, its core feature |
| Convert models into game formats | Yes, GLB to YDR, peds, weapons, and more | No |
| Install required | None | Windows installer |
| Platforms | Any modern browser | Windows |
The honest split
Use the browser tools when the job is about the files: opening archives on any system, checking a model before installing it, pulling textures, converting a GLB, or packaging a FiveM resource. Keep OpenIV around if you mod a single player installation directly, because writing into the game folder is inherently a desktop job.
Start with the file you have
- An .rpf archive: open it in the RPF browser, or build a new one.
- A model: YDR, YDD, or YFT preview shows it in 3D.
- Textures: the YTD preview lists and exports every texture.
- New to all of it: the RPF guide walks through the format.
Frequently asked questions
- Can I open RPF files without OpenIV?
- Yes. The RPF browser opens GTA 5 archives in your browser, including nested archives, and lets you browse the file tree and extract files. Nothing gets installed and files stay on your device.
- Does it work on Mac and Linux?
- Yes. Everything runs in the browser, so any system with a modern browser works. OpenIV itself is Windows software.
- Can it install mods into my game folder?
- No. A browser cannot write into your GTA installation, and that part remains a job for desktop tools. What you can do here is open, inspect, convert, and build the files themselves.
- Can I create archives too, or only open them?
- Both. The RPF builder assembles new archives, including dlc.rpf packs for FiveM resources, from files you drop in.
