<p>Any GitHub, Bitbucket or GitLab Commit, Pull Request or Merge Request urls.</p>
<p>Any Git or Unified Raw Diff or Patch urls.</p>

<li>
<b>Can I send a custom url for a friend, colleague or co-worker?</b>
<p>Just add a url parameter called diff to current url using as value your Commit, Pull Request, Merge Request, Diff or Patch url.</p>
<p>ex: <a href="url.html?diff=https://github.com/rtfpessoa/diff2html/pull/106">https://diff2html.xyz/url?diff=https://github.com/rtfpessoa/diff2html/pull/106</a></p>
<p>You can also use an hashtag (# or #! or #!/) in the end of the url.
This will be overridden if you click any href id and for that reason not advised.</p>
</li>
<li>
<b>Why can't I paste a diff?</b>
<p><a href="https://diffy.org/">diffy.org</a> is an amazing tool created by <a href="https://github.com/pbu88">pbu88</a>
to share your diffs and uses diff2html under the hood.</p>
<p>Also, diff2html cli can directly publish diffs to <a href="https://diffy.org/">diffy.org</a></p>
