WHY CONVERT
Why convert TSV to CSV
02
Acceptance by downstream tools
CSV is the format most receiving systems expect for this kind of content. Converting upstream avoids the rejection and silent re-encoding that often happen when TSV reaches an unprepared pipeline.
03
Portable, predictable file format
CSV is well documented and decodable by long-lived tooling, which matters for archives, deliverables, and any file that needs to outlive the software that created it.

— FAQ
Frequently asked.
Is TSV to CSV conversion free?
Yes. LocalConvert is completely free, with no signup and no per-file or per-day limits.
Do my files get uploaded anywhere?
No. TSV to CSV conversion happens entirely inside your browser using WebAssembly — your file never leaves your device.
What's the maximum file size?
There's no fixed cap — the practical limit is your device's available memory. Very large files may take longer or fail on low-RAM devices.
Does it work offline?
Yes — once the page has loaded, TSV to CSV conversion works without an internet connection. Re-open the page once to cache it.
Will conversion preserve quality?
LocalConvert uses the industry-standard tools (FFmpeg, ImageMagick, Pandoc) — quality matches what professionals use on the command line. Lossy formats will still lose some quality on each re-encode.
