Image Hosting for GitHub README files.
Committing screenshots and diagrams straight into a repo feels easy until the .git folder is 200 MB and a fresh clone crawls. Upload your image here instead, copy the direct link, and drop it into your README with one line of Markdown. The file sits on a CDN, not in your git history, so the repo stays small and the README still renders the picture inline. It works the same for public and private projects, profile READMEs, wikis and issue threads.

How to Use in Markdown
Upload Your Image
Drag and drop your screenshot or diagram into our uploader to get a permanent, CDN-backed URL instantly.
Copy the URL
Once the upload completes, copy the generated link to your clipboard for use in any Markdown file.
Paste into README
Use standard Markdown syntax like  to display your image directly in your GitHub README.
Why Not Commit Images to Repos
Bloats Your Repository
Git tracks every version of every file. Binary images cannot be delta-compressed, causing your .git folder to balloon in size.
Slows Down Clones
Every git clone downloads the entire history. Large image files force contributors to wait minutes just to get started.
Clutters Your Diffs
Binary files add noise to pull requests and cannot be meaningfully reviewed, making it harder to track actual code changes.
One clean link for badges and banners
A direct https link is handy beyond the README too. Reuse the same URL for a project banner, a shields.io style badge background, or a screenshot you reference from the docs and the wiki, without copying the file into three places.
Hosted link vs committing the image
There are a few ways to get an image into a README. They mostly differ on what happens to your repo size, how fast a clone runs, and whether the link stays put. Here is how the common options compare.
| Approach | Repo size | Clone speed | Update without a commit | Stable link |
|---|---|---|---|---|
| Hosted link (ImageToURL) | No impact | Unaffected | Yes, swap the file at the URL | Yes, forever when signed in |
| Commit image into the repo | Grows with every edit | Slower over time | No, needs a new commit | Yes, but it bloats history |
| Paste into an issue (githubusercontent) | No impact | Unaffected | No | Can break if the issue changes |
| Git LFS | Smaller checkout | Needs LFS set up | No, needs a new commit | Yes, within storage quotas |
| Imgur link | No impact | Unaffected | Yes | Account-tied, no anon since 2023 |
Markdown vs HTML for README images
GitHub READMEs are Markdown, and the plain image syntax is . That embeds the picture inline as long as the URL points straight at the file. GitHub Markdown also accepts a bit of HTML, which is the trick for sizing and alignment: <img src="https://your-image-url" width="480" alt="app screenshot">. Use the Markdown form for simple images and the <img> tag when you need a fixed width, a banner that does not span the full column, or a centered logo. Both read the same direct link, so you upload once and pick whichever syntax fits.
Why keep binary images out of the repo
Git stores history, and it cannot delta-compress binaries the way it does text. Edit a 1 MB screenshot ten times and you can carry close to 10 MB of dead weight that every clone and fetch has to pull, forever. The README still looks identical either way. Linking to an external file keeps the working tree to code and docs, so pull request diffs stay readable and new contributors get going in seconds. If you already committed big images, an external link is the cheap fix going forward, and history rewriting tools handle the cleanup if you want the old copies gone.
Will the links stay up?
Files are served over HTTPS from a CDN, so they load independently of GitHub and work in private repos too. One honest note on lifetime: anonymous uploads stay live for a couple of weeks at minimum and are cleared on a monthly cleanup, which is fine for a quick issue screenshot. For a README image you want around long term, sign in for free and choose keep forever so the link does not vanish. Either way, keep the original file in hand, and remember anonymous uploads are public to anyone with the URL.
Where a hosted image link helps
Once your picture has a direct link, it slots into the spots a README usually needs:
Banner and logo at the top
Put a project banner or logo above the title with . HTML works too, so <img src="url" width="480"> keeps it from filling the whole page.
Screenshots and demo GIFs
Show the tool actually running. A GIF or a few screenshots make a README far more convincing than a wall of text, and they never touch your clone size.
Profile READMEs, wikis and issues
The same link drops into your github.com/username profile README, wiki pages, and issue or pull request comments wherever GitHub renders Markdown.
Frequently Asked Questions
Why should I not commit images directly to my GitHub repo?
Git tracks every version of every file. Binary image files cannot be diffed efficiently, so every change adds the full file size to your repo history, bloating your .git directory.
How do I add an externally hosted image to a GitHub README?
Upload your image to ImageToURL, copy the permanent URL, then add it to your README using standard Markdown syntax: .
Will the images load on private repositories too?
Yes. Since the images are hosted externally on our CDN, they load independently of GitHub's access controls, working perfectly in both public and private repos.
Do ImageToURL links work in GitHub wikis and issues?
Absolutely. ImageToURL links work anywhere GitHub renders Markdown, including wiki pages, issue comments, and pull request descriptions.
What is the exact Markdown syntax for a README image?
Use . The alt text shows if the image fails to load and helps screen readers. As long as the URL points straight at the file, GitHub renders it inline.
How do I set the width or center an image in a README?
GitHub Markdown allows HTML, so use an <img> tag: <img src="https://your-image-url" width="480" alt="screenshot">. To center it, wrap it in <p align="center">...</p>. Plain  has no size control.
Can I host a demo GIF for my README?
Yes. GIF is supported up to 50 MB. Upload it, copy the link, and embed it the same way as a static image. A short demo GIF often explains a project faster than paragraphs of text.
Do the links expire?
Anonymous uploads last a couple of weeks at minimum and are cleared on a monthly cleanup, which suits a quick issue screenshot. For a README image you want around long term, sign in for free and choose keep forever. Keep the original file as a backup either way.
What happens if the host has an outage?
Files are served from a CDN replicated across edge locations, so brief issues are rare and load is spread out. No external host is guaranteed forever, though, so for critical project images sign in and keep the original so you can re-upload if needed.
What image formats and sizes are supported?
JPG, PNG, WebP, GIF and SVG, up to 50 MB per file. The link ends in the real extension, so it embeds in Markdown exactly like the original file would.
Does it compress or resize my image?
No. You get back the same file at full quality, with no re-compression and no watermark. A logo or diagram stays crisp in the rendered README.
