Which ID formats does the decoder support?

It supports Discord, Twitter, Mastodon, Sonyflake, Instagram, and custom Snowflake-style bit profiles.

Can it decode large 64-bit IDs without losing precision?

Yes. The tool is designed to parse 64-bit Snowflake-style IDs without precision loss.

What does the Discord shard count do?

When supplied, the shard count lets the tool infer a Discord shard for the decoded ID.

How do I define a custom profile?

Select Custom, provide an epoch, choose the timestamp unit, and enter a JSON field list ordered from the least significant bits first.

Which timestamp units are available for custom profiles?

Custom timestamps can use milliseconds, 10-millisecond units, or seconds.
