Working with large files

Processing happens in your browser tab, so the ceiling is your device's memory rather than a quota we set.

Rough guidance

• Under 1 MB — instant on any device.
• 1–5 MB — comfortable on a laptop; a warning appears above 5 MB.
• 5–25 MB — works on a reasonable machine, but expect a pause. The CSV viewer stops at 100,000 rows.
• Above 25 MB — a browser tab is the wrong tool. Use jq, ripgrep or a real editor.

If the tab freezes

Syntax highlighting is disabled automatically past about 120 KB. Turning off line wrapping in preferences also helps. Regex evaluation runs in a worker with a time limit, so a runaway pattern is stopped rather than locking the page.

The trade-off

A server-side tool could stream a gigabyte file — by receiving your gigabyte file. Local processing means the memory is yours and so is the limit.
