# itty.bitty.site
|
||
|
||
itty.bitty takes html (or other data), compresses it into a URL fragment, and provides a link that can be shared. When it is opened, it inflates that data on the receiver’s side.

Detailed workings [how.bitty.site](http://how.bitty.site)
|
||
|
||
## Advanced
|
||
|
||
**Handcrafted HTML files**
|
||
|
||
Drag one into the editor to convert it.
|
||
|
||
**Using Codepen.io (Pro Accounts)**
|
||
|
||
Paste a codepen URL into the editor. Get started with a [template](https://codepen.io/pen?template=MXgrEr) or look at [some samples](https://codepen.io/collection/XprVQL/). This must be a Pro account to work.
|
||
|
||
**Hosting**
|
||
|
||
One simple way to host is to [forward a domain](https://support.google.com/domains/answer/4522141?hl=en). Just paste the itty.bitty url in the redirect.
|
||
|
||
## Generating links programmatically
|
||
Encoding (Mac)
|
||
|
||
```echo -n 'hello world' | lzma -9 | base64 | xargs -0 printf "https://itty.bitty.site/#/%s\n"```
|
||
|
||
Encoding (Linux)
|
||
|
||
```echo -n 'hello world' | lzma -9 | base64 -w0 | xargs -0 printf "https://itty.bitty.site/#/%s\n"```
|
||
|
||
Encoding (Win Git/WSL)
|
||
|
||
`echo -n 'hello world' | xz --format=lzma -9 | base64 -w0 | printf "https://itty.bitty.site/#/%s\n" "$(cat -)"`
|
||
|
||
Encoding (Python)
|
||
|
||
`'https://itty.bitty.site/#/'+base64.b64encode(lzma.compress(bytes("hello world",encoding="utf-8"), format=lzma.FORMAT_ALONE, preset=9)).decode("utf-8")`
|
||
|
||
Encoding (Node.js)
|
||
|
||
`'https://itty.bitty.site/#/'+Buffer.from(lzma.compress("Hello World", 9)).toString('base64')`
|
||
|
||
Decoding (Mac)
|
||
|
||
`echo -n "[URL]" | sed -E 's/^.*#[^\/]*\/\??//g' | base64 -D | lzma -d `
|
||
|
||
Decoding (Linux)
|
||
|
||
`echo -n "[URL]" | sed -E 's/^.*#[^\/]*\/\??//g' | base64 -d | lzma -d`
|
||
|
||
Decoding (Win Git/WSL)
|
||
|
||
`echo -n "[URL]" | sed 's/^.*#[^\/]*\///g' | base64 -d | xz --format=lzma -d`
|
||
|
||
|
||
**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|

|
||
| Discord | 4,000 |
|
||
| iMessage | 4,000 | URLs with more than 300 nonbreaking characters in a row will be split.<br>LZMA compression usually fixes this, but raw data urls may fail. |
