*://Works with any custom protocol URL
Paste your custom scheme URL
Enter any URL that uses a custom protocol like slack://, obsidian://, zoom://, or notion://. These URLs break when embedded in web pages, emails, or documentation because browsers do not recognize them as valid links.
Choose your redirect mode
Auto-redirect opens the link immediately when someone clicks it. Manual mode shows a confirmation page first. Compression uses stateless LZ encoding to shorten the URL without any database or server storage.
Share the universal link
Copy the generated HTTPS link and use it anywhere. It works in Notion pages, Obsidian notes, Slack messages, emails, documentation, and any other context where custom scheme URLs would break.
What is a custom scheme URL?+
A custom scheme URL uses a non-standard protocol like slack://, obsidian://, or zoom:// instead of https://. Apps register these schemes to handle deep links, but they break when pasted into web pages, emails, or documentation because browsers do not recognize them.
Why do custom scheme links break in Notion and Obsidian?+
Web-based apps like Notion strip or block non-HTTPS URLs for security reasons. When you paste a slack:// or obsidian:// link into a Notion page, it either becomes unclickable or gets removed entirely. Shortlink solves this by wrapping the custom scheme URL in a standard HTTPS link.
Does Shortlink store my URLs?+
No. Shortlink is completely stateless. Your URL is encoded directly into the link itself using client-side compression. There is no database, no server storage, and no tracking. The original URL can be decoded from the link without contacting any server.
Is Shortlink free?+
Yes, Shortlink is free and open source. There are no usage limits, no signup requirements, and no premium tiers. The source code is available on GitHub.
How does the compression work?+
Shortlink uses LZ-string compression with a custom dictionary of common URL patterns. The URL is first pattern-matched against known schemes, then compressed using LZ encoding, and finally made URL-safe. The entire process happens in your browser with zero server involvement.
