Free Web Tools

iMeshh runs a set of free tools that work entirely in your browser, with no upload and no sign-in. Your file is read and rendered on your own machine and never leaves it.

• GLB & glTF viewer — orbit and inspect a model, light it with HDRI environments, and switch on photoreal path tracing with real depth of field.
• GLB to STL converter — turn a GLB into an STL for 3D printing, with a scale option for slicers.
• LOD generator — generate levels of detail that preserve UVs, with a live before-and-after preview.

Photoreal mode

The viewer's Photoreal mode is a progressive path tracer that runs on your GPU. It starts grainy and refines over a few seconds into a clean, physically lit still you can screenshot. It needs a desktop browser with WebGL2, and the optional AI denoiser needs WebGPU. The first start compiles a large shader on your graphics driver, which can take up to a minute; after that it is quick.

Fixing slow rendering or a denoiser that will not run

Both problems almost always come down to one thing: the browser is not using your dedicated GPU. On a laptop or a multi-GPU desktop, Windows often hands the browser the integrated graphics, which is far slower and whose WebGPU can return unusable output. Forcing the browser onto the dedicated GPU commonly transforms render speed and makes the denoiser work.

Work through these in order:

1. Windows: set the browser to your dedicated GPU. Open Graphics settings (press the Windows key and type "Graphics settings"). Under the custom options, click Browse and add your browser's executable, for Chrome usually C:\Program Files\Google\Chrome\Application\chrome.exe. Select it, click Options, choose High performance (confirm it names your dedicated card, for example an NVIDIA GeForce RTX card), and Save. Relaunch the browser. This step alone can make the biggest difference.
2. NVIDIA Control Panel: prefer maximum performance. Right-click the desktop, open the NVIDIA Control Panel, go to Manage 3D settings, then the Program Settings tab, and select Google Chrome (add it if it is not listed). Set Power management mode to Prefer maximum performance, and turn Background Application Max Frame Rate off so it does not throttle the browser. Click Apply.
3. Turn on browser hardware acceleration. In Chrome, open Settings, then System, and enable "Use graphics acceleration when available". Relaunch.
4. Check chrome://gpu. Open chrome://gpu. If WebGPU shows "software" or "reduced performance", update your graphics driver and your browser to the latest versions, then relaunch and check again.
5. Avoid remote sessions. Remote Desktop and other remote connections force software rendering, so Photoreal and the denoiser can only run at the physical machine.

If Photoreal still will not run after all of this, the viewer includes a small on-page diagnostic that reports exactly what your device's WebGPU is doing; the tool links to it when the denoiser fails.

Your files stay private

Every one of these tools runs client-side. Nothing you open is uploaded to iMeshh or anywhere else. When you load a model from a URL, your browser fetches it directly from that host; it never passes through our servers.
