Size Limits
While most sites support 2000 bytes, some can handle more. Maximum sizes for links in various apps & Browsers (approximate, size in bytes)
| App | Max bytes | Notes |
|---|---|---|
| 4,088 | ||
| Slack | 4,000 | |
| Discord | 4,000 | |
| iMessage | 4,000 | URLs with more than 300 nonbreaking characters in a row will be split. LZMA compression usually fixes this, but raw data urls may fail. |
| QR Code | 2,953 | |
| Bitly | 2,048 | |
