Nope, but you can zip your data and encode them to better encoding and fit much more data inside. But it’s not trivial, I’ve spend a lot of time experimenting with this.
For example, here is some compression libraries comparison using real life bookmarks-like data:
// LZ-UTF8 35 ms, ratio: 0.37, 81_284, original: 219_999
// zstd: 114 ms, ratio: 0.26, 57_131, original: 219_999
// LZMA 1660 ms, ratio: 0.25, 54_467, original: 219_999
// brotli 323 ms, ratio: 0.24, 51_733, original: 219_999
Then you need to serialize it into something that will take as little space as possible, ideally Base93, which can be crazy slow (even slower than the compression).
