Inspect Source Map Files Online

A source map connects generated JavaScript or CSS positions back to original source locations. Anyfile parses the map, summarizes coverage and lets you query mappings without loading the generated program.

Choose a .map file

Your file stays on this device

Anyfile reads only the local file you select. Parsing, decoding and rendering happen in this browser tab; the file is not uploaded to Anyfile servers.

What Anyfile can show

Source and name indexes
Embedded sourcesContent when present
Generated-to-original position lookup and coverage

Limits and conditions

Missing sourcesContent cannot be reconstructed
Malformed or nonstandard mappings may be rejected

Common question

Does a .map file include the original source?

Sometimes. Anyfile shows sourcesContent when embedded; otherwise it can only display source paths and mappings.
