What this conversion produces
Fix a file whose encoding does not match the application that needs to read it. Select the source charset explicitly, then choose the target charset. This helps prepare legacy CSV imports, text exports and configuration files. The converter checks whether decoding and re-encoding can preserve the source and whether the target can represent the resulting characters.
Supported input and practical limits
Encoding detection is not guessed automatically: selecting the wrong but technically valid source charset can still produce incorrect text. Lossy target conversion and malformed source bytes are rejected using a roundtrip check. A leading byte-order mark is treated as an encoding signature rather than text. Output uses no BOM, so select the charset explicitly when importing it. Input is limited to 4 MiB and decoded text to two million characters.
What should I know before converting?

Is input uploaded?
This tool sends input to this site’s conversion API after you select Convert on server. Files use bounded workers and, when needed, private temporary folders deleted after processing or cancellation. No conversion history is saved. The converter does not upload files to a third-party conversion service.
