What is Snowflake ID Decoder?
The Snowflake ID Decoder turns 64-bit snowflake identifiers from Discord, Twitter/X, and Instagram back into human-readable data: the exact creation timestamp, the worker or shard that generated the ID, and the per-millisecond sequence number. Paste a single ID or a whole batch, pick the platform, and get a table with timezone-aware dates plus a bit-level breakdown — entirely offline in your browser.
Key Benefits
- Recover the creation date of accounts, messages, and tweets without any API call
- Platform presets for Discord, Twitter/X, and Instagram prevent wrong-epoch mistakes
- Custom epoch mode supports private snowflake implementations and other platforms
- Batch decoding with CSV export for moderation logs and data analysis
- Bit-level breakdown shows binary, hex, worker, and sequence fields side by side
Common Use Cases
- •Finding out when a Discord account or server was created from its ID
- •Dating tweets, DMs, or Instagram media during moderation and investigations
- •Debugging distributed systems that generate snowflake-style IDs
- •Auditing logs by converting batches of IDs into sortable timestamps
Decode Snowflake IDs to Timestamps
- Pick the platform: Select Twitter/X, Discord, Instagram, or Custom epoch — the bit layout hint updates to match, and custom mode lets you enter any epoch in milliseconds.
- Choose a timezone: Pick from the timezone dropdown, such as Bangkok (GMT+7) or UTC, to control how the Created At column is formatted.
- Paste the IDs: Enter one snowflake per line — commas, semicolons, spaces, and tabs also work — and the table fills with timestamps, worker IDs, and sequence numbers instantly.
- Export the results: Remove invalid rows with one click, then Copy all as TSV or download snowflake-ids-decoded.csv, and check the Bit-Level Breakdown for the binary and hex of the first valid ID.
Key Features
- One-click presets for Discord, Twitter/X, and Instagram snowflake epochs
- Custom epoch mode for private or less common snowflake implementations
- Bit-level breakdown with binary, hexadecimal, worker, and sequence fields
- Batch-decode unlimited IDs separated by lines, commas, or spaces
- 18 timezone display options plus UTC ISO 8601 output and CSV export
- 100% client-side — IDs never leave your browser
Frequently Asked Questions
Which platforms are supported?
Twitter/X, Discord, and Instagram presets with their official epochs, plus a custom epoch field for any other snowflake-style ID — enter the epoch in milliseconds and the tool applies the standard high-bit timestamp layout.
Can I decode many IDs at once?
Yes — paste one ID per line, or separate them with commas, semicolons, spaces, or tabs. The table decodes each one instantly and invalid entries are flagged so you can remove them with one click.
What do the worker and sequence columns mean?
They are the low bits of the ID: the machine or shard that generated it and the per-millisecond counter. The Bit-Level Breakdown panel also shows the full 64-bit binary and hexadecimal form of the first valid ID.
Is it safe to paste message or user IDs here?
Yes — decoding happens entirely in your browser and nothing is uploaded or stored. Copy all exports the results as TSV, or download snowflake-ids-decoded.csv for spreadsheets.
