Data recovery reviewer
Distinguish malformed UTF-8 from genuine replacement characters.
Try 11111111, inspect refusal, then decode valid UTF-8 for emoji.
Invalid bytes produce no partial output; valid multibyte sequences decode correctly.
Binary to Text
Decode binary bytes with strict UTF-8 or ASCII validation. Choose token grouping and BOM handling, inspect every byte, and export the complete decoded text.

How it works
A dedicated interactive panel for this data format or operation
- Start with the included valid sample, then replace it with your own input.
- Review errors and compare the output before replacing source data.
Choose your path
Built around the job you need to finish
Decode a fully validated binary byte sequence with explicit grouping, UTF-8/ASCII and BOM policies, refusing corrupted or partial text.
Integration tester
Control byte boundaries and BOM interpretation.
Compare spaced bytes with continuous mode and decode a double BOM with keep/remove policies.
Grouping is intentional and only one leading BOM is removed when selected.
Mobile log analyst
Review byte evidence without losing the decoded result.
Import notation, correct a malformed token, page a 220-byte review and export.
Errors retain source and full decoded text remains available beyond the preview cap.
Authoritative checks for this tool
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.
- Encoding StandardWHATWG · UTF-8 byte encoding and fatal decoding, including explicit BOM handling; ASCII here is separately constrained to 0–127.
- Unicode scalar values and encoding formsUnicode Consortium · Scalar values exclude surrogate code points; UTF-16 units and UTF-8 bytes are distinct from visible grapheme clusters.
- File APIW3C · UTF-8 local file reading and transparent Blob line endings; requesting a download does not prove an OS-saved file.

How it works
Updated August 2026Validate notation
Spaced mode requires exactly eight bits per token, separated only by ASCII spaces, tabs or line breaks. Continuous mode requires an unseparated multiple of eight bits.
Decode deliberately
UTF-8 uses fatal decoding; strict ASCII rejects bytes above 127. Keep a leading U+FEFF or explicitly remove one without altering interior markers.
Inspect original bytes
The byte review describes the input bytes even if you remove a decoded BOM. Complete decoded output, copy and text export are separate from the bounded preview.

Common Mistakes to Avoid
Common Mistakes to Avoid
Joining malformed short tokens
Use complete eight-bit tokens or deliberately select a valid continuous stream; the tool does not pad or stitch broken tokens.
Accepting replacement glyphs as successful recovery
Correct invalid bytes using the source system; the tool refuses malformed UTF-8 rather than guessing lost characters.
FAQ
It is a byte value but not valid UTF-8 text. The decoder does not substitute a replacement glyph or return a partial prefix.
Yes. Select Continuous bits. Internal spaces, prefixes and incomplete bytes are refused in that mode.
Here ASCII is strictly 0–127. High bytes are not reinterpreted as Windows-1252 or Latin-1.
Keep is the default. Remove deletes exactly one decoded leading U+FEFF. A BOM in a notation source file is separate and can be removed explicitly with undo.
This tool downloads the decoded text as UTF-8 .txt, not arbitrary binary bytes. Preview pagination does not truncate it. Verify the saved file; no automatic Project save is performed.
About Binary to Text
Decode only complete, valid byte notation. The tool reports malformed data instead of returning a silently repaired message, and keeps the source available for correction.
