Enable hardware acceleration in your browser
FASHN's built-in image editor (the crop, rotate, and annotate tool you open from the Studio) uses WebGL to render the canvas. WebGL relies on hardware acceleration, which lets your browser draw graphics with your GPU instead of your CPU.
If you see the message "Missing WebGL Support" when opening the editor, your browser most likely has hardware acceleration turned off, or your device is using an outdated browser or graphics driver. This guide walks you through the fix.
These settings live in your browser, not in FASHN. After changing them you will need to restart the browser and reopen the editor.
Before changing any settings
Try the quick checks first. They resolve most cases without touching browser flags.
Update your browser
Open your browser's About page and install any pending update. Older versions of Chrome, Edge, Firefox, and Safari ship with stricter graphics policies that can block WebGL on some hardware.
Restart your computer
A reboot clears stuck GPU processes and applies any pending graphics driver updates.
Disable extensions that block scripts or graphics
Privacy and script-blocking extensions (uBlock Origin in strict mode, NoScript, Privacy Badger, and similar) can disable WebGL on individual sites. Pause the extension on app.fashn.ai and reload.
If the editor still shows the missing WebGL message, enable hardware acceleration using the steps for your browser below.
Enable hardware acceleration
Still not working?
If hardware acceleration is on and you have updated your browser, your device may not support WebGL with its current setup. Try the following in order:
- Switch browsers. Open FASHN in Chrome, Edge, or Firefox on a desktop computer.
- Update your graphics drivers. On Windows, run Windows Update or use your GPU vendor's tool (NVIDIA GeForce Experience, AMD Software, Intel Driver & Support Assistant). On macOS, drivers ship with the OS, so a system update is enough.
- Try a different device. If you are on a managed work laptop, GPU drivers and WebGL may be restricted by your IT policy.
- Skip the editor for now. You can still upload, generate, and download images without entering the built-in editor. Use a desktop image editor for crops and annotations until WebGL is available.
If none of the above works, reach out through any of the channels listed on the Support page and include:
- Your browser name and version.
- Your operating system and version.
- A screenshot of the Missing WebGL Support message.
- (Optional, but very helpful) The contents of
chrome://gpu,edge://gpu, or the Graphics section ofabout:supportin Firefox.
