How we tested
Every tool on this list is free, runs (mostly) in the browser, and converts Unix timestamps to readable dates and back. We scored each on the seven criteria developers actually care about, verified on 2026-08-14: unit coverage (seconds, milliseconds, microseconds, nanoseconds), batch conversion with export, code snippets, timezone support, specialist formats beyond Unix time, whether the tool runs client-side, and how transparent it is about its own math. We also read ToolBox's independent comparison of Unix timestamp tools and the Stack Overflow discussion of epoch vs Unix time while researching.
Disclosure: Real Epoch Converter is our own tool. It is included because it genuinely belongs in this category, it is clearly labeled, and the ranking reflects features we verified — not sponsorship. Nothing on this list paid for placement.

1. Epoch Converter — epochconverter.com
Best overall reference. The site that has ranked #1 for "epoch converter" for years, and for good reason: it shows the current epoch in seconds, milliseconds, microseconds, and nanoseconds, converts both directions, and carries code examples in more than 20 languages — including R, Lua, Dart, Excel formulas, and four SQL dialects. It adds a batch page with CSV export for Excel, a timezone page, epoch dates for the start and end of each year/month/day, and a seconds-to-duration calculator. Everything runs client-side.
- Pros: nanosecond support; the largest snippet library; batch + CSV; a decade of authority.
- Cons: Unix time only — no snowflake IDs, LDAP, GPS, or other specialist formats; no visible review dates or methodology.
- Best for: quick lookups, nanosecond work, and language-snippet reference.
2. Real Epoch Converter — realepochconverter.com
Best for specialist formats and batch work. Our own tool, disclosed. It
auto-detects seconds, milliseconds, and microseconds (with manual override), converts
batches with TSV/CSV export and per-row unit detection, and supports 450+ IANA timezones
through the browser's Intl data. Its real edge is breadth: fifteen dedicated
converters for snowflake IDs,
LDAP / Active Directory,
GPS time, NTP,
.NET ticks, HFS+,
Excel dates,
UUID v1/v7 & ULID,
Chrome/WebKit time, and more. There is no
backend: input never leaves your device, and every behavior is documented on the
methodology page with dated bylines and cited specs.
- Pros: 15 specialist converters; batch with TSV/CSV; unit auto-detection; 450+ timezones; transparent, dated methodology.
- Cons: no nanosecond support; snippet library covers 10 languages rather than 20+.
- Best for: decoding non-Unix timestamps, spreadsheet batches, and anyone who wants to know how the math works.
3. Unix Time Stamp — unixtimestamp.com
Best minimalist display. A single, uncluttered page built around a large live clock. It supports seconds, milliseconds, microseconds, and nanoseconds, converts both directions, and works online or client-side. If you want the current epoch on screen with zero distraction, this is the one.
- Pros: clean; fast; four units; both online and client-side.
- Cons: no batch export, no snippets, no specialist formats.
- Best for: reading the epoch "now" and simple single-value conversions.
4. Epoch Converter — epochconverter.io
Best modern interface. A polished, developer-friendly UI that converts timestamps in seconds, milliseconds, and microseconds to human-readable dates and back, with timezone-aware human input. Simple, fast, and pleasant to use for everyday Unix time work.
- Pros: clean design; both directions; easy date-with-timezone input.
- Cons: no batch, snippets, or specialist formats.
- Best for: developers who value UI polish for day-to-day lookups.
5. Epoch Convert — epochconvert.com
Best multilingual option. Supports seconds, milliseconds, microseconds, and nanoseconds, UTC and named timezones, and ISO 8601 input — with the interface localized into several languages. A solid all-rounder if you (or your team) work in a language other than English.
- Pros: four units; timezone + ISO support; localized interface.
- Cons: no batch export; no snippets; no specialist formats.
- Best for: non-English speakers and ISO-heavy workflows.
6. Timestamp Converter — timestamp-converter.com
Simple and direct. A no-frills converter aimed at developers: paste an epoch and read a date, or type a date and get the timestamp, in seconds, milliseconds, and microseconds. Nothing extra, nothing in the way.
- Pros: focused; fast; three units.
- Cons: minimal feature set beyond the core conversion.
- Best for: a quick, distraction-free conversion.
7. Epoch Utils — epochutils.com
Best curated collection. Converts Unix timestamps to human-readable dates and back as part of a larger, hand-curated set of developer utilities. If you like having several small tools under one roof, this is a tidy option.
- Pros: works; part of a broader tool collection.
- Cons: core feature set only; no batch or snippets.
- Best for: people who already use Epoch Utils for other tools.
8. Liquid Web Unix Timestamp Converter
Best brand-backed simplicity. A free, browser-based converter from the well-known hosting company Liquid Web. It turns a date into a Unix timestamp and a timestamp back into a date, with local-time display. Trustworthy, zero-friction, and slightly limited.
- Pros: reputable maintainer; free; browser-based.
- Cons: basic feature set; seconds/milliseconds focus.
- Best for: a quick conversion from a name you already trust.
How to choose
- Plain Unix time, fast: unixtimestamp.com or timestamp-converter.com.
- Nanoseconds or rare language snippets: epochconverter.com.
- Snowflake IDs, LDAP, GPS, Excel dates, or a whole batch: Real Epoch Converter.
- Non-English interface: epochconvert.com.
- A name you already trust: Liquid Web's converter.
Whichever you pick, the fundamentals are the same: a Unix timestamp is the number of seconds since 1970-01-01 00:00:00 UTC. If a tool's numbers disagree, check the methodology behind it.
