GitHub Raw Link Generator: Convert Blob & Gist URLs to Direct CDNs
Convert GitHub file URLs into direct raw.githubusercontent.com links and jsDelivr CDN endpoints with valid CSS/JS MIME types. Fast, private, and 100% in-browser.
text/plain; browsers will block this if loaded as CSS or JS.

How to Convert GitHub Links in 3 Steps
Copy GitHub File URL
Open your file in any public GitHub repository and copy the URL from your browser address bar (it typically contains /blob/).
Paste in Generator
Paste the link into the converter. The engine automatically parses the repository owner, branch, file path, and file extension.
Select Raw or Production CDN
Use the direct raw link for downloads, or pick the jsDelivr CDN link to embed stylesheets and scripts with valid Content-Type headers.
The Complete Guide to GitHub Raw Links, MIME Types & CDNs
When hosting open-source code or web assets on GitHub, linking files directly to external web pages often leads to unexpected browser errors. Understanding how GitHub serves raw files is critical for developers.
Why raw.githubusercontent.com Blocks CSS and JavaScript
If you include a CSS or JS file directly from raw.githubusercontent.com in your HTML code, modern browsers will refuse to execute it. This is caused by two HTTP headers GitHub intentionally sends:
- Content-Type: text/plain; charset=utf-8: GitHub serves all raw files as generic plaintext regardless of extension.
- X-Content-Type-Options: nosniff: This security header instructs browsers not to guess (sniff) the MIME type. Since the browser sees
text/plaininstead oftext/cssorapplication/javascript, the file is rejected.
GitHub enforces this policy to prevent attackers from using free repository storage as a malware or phishing delivery network.
How jsDelivr and Statically Solve the MIME Type Problem
Open-source Content Delivery Networks (CDNs) like jsDelivr and Statically mirror public GitHub repositories across thousands of global Anycast edge nodes. They inspect file extensions, attach the correct MIME headers (e.g., Content-Type: text/css), and deliver aggressive caching with Brotli and Gzip compression.
Branch Links vs Permanent Commit SHAs
When generating raw links, you can reference either a branch name (like main or master) or a specific commit hash (like 4a1b2c3d):
- Branch Link (
/main/): Automatically updates as you push new code, but CDN edge caches may delay updates for up to 24 hours. - Commit Hash Link (
/4a1b2c3d/): Permanently immutable. Never changes and avoids cache invalidation issues, making it ideal for production websites and libraries.
GitHub Link Formats & CDN Comparison Matrix
Reference guide for choosing the optimal URL format for your use case:
| Link Format | MIME Type Handling | Caching / Latency | Best Used For |
|---|---|---|---|
| GitHub Web View | HTML Webpage | No CDN (Standard page) | Human reading, code reviewing, issue tracking |
| Raw GitHub | Enforced text/plain |
Fast origin, minimal cache | Raw text downloads, cURL scripts, config files |
| jsDelivr CDN | Correct MIME Types (CSS/JS) | Global Anycast CDN cache | Live web embedding, stylesheets, script tags |
| Statically CDN | Correct MIME Types | Multi-CDN edge network | Alternative CDN for images, fonts, and assets |
| GitHub Gist Raw | text/plain |
Origin cache | Code snippet sharing, pastebin alternatives |
Frequently Asked Questions
Simply paste your GitHub URL (e.g. https://github.com/user/repo/blob/main/file.js) into the input field above. The tool automatically replaces github.com with raw.githubusercontent.com and strips the /blob/ path segment in real time.
jsDelivr is a free, open-source public CDN sponsored by major cloud providers. There are no strict monthly bandwidth caps for legitimate open-source libraries and web assets, though individual files over 50 MB are not recommended.
With jsDelivr, you can purge the cache by adding /purge/ before the path (e.g. https://purge.jsdelivr.net/gh/user/repo@branch/file.css). Alternatively, reference a new release tag or commit SHA to get a fresh URL instantly.
No. 100% of URL parsing and transformation runs locally inside your browser's client-side JavaScript engine. No links are logged, saved, or uploaded.
