Choose your path
Compare two independent originals through bounded line alignment, retaining exact and explicitly ignored differences in a review report.
Avoid false changes after a line insertion.
Paste original and revised text separately, compare, inspect original line numbers and hide unchanged preview rows.
Later matching lines stay aligned; full report retains both originals.
Separate content changes from intentional whitespace or case differences.
Compare exact text, then enable one normalization policy and inspect equivalent rows.
Ignored differences are disclosed, not mislabeled identical.
Review CRLF/LF and missing final terminators.
Import two UTF-8 files, compare before editing, adjust newline policies, swap sides and request the report.
Decoded terminators remain visible; report is not presented as an apply-ready patch.
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.

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.
Decode complete Morse tokens with explicit slash or line-break word boundaries. Refuse unknown signals, inspect character rows, and export the full transcript.
Each line retains its text and CR, LF, CRLF or absent terminator. Empty lines are real tokens. Imported UTF-8 preserves decoded endings; editing or pasting through a textarea can normalize them.
The pinned jsdiff engine aligns line keys under explicit whitespace, ending and case policies. Limits are 100,000 characters and 2,000 lines per side, 2,000 edits or 1.5 seconds for alignment, and a 10-second outer worker timeout.
Rows are added, removed, exactly unchanged or equivalent under selected options. Report text quotes original values and terminators. Moves are edits, repeated lines may align in different valid ways, and the report is not a patch.

Equivalent means a chosen policy ignores differences; check both original values.
It is a human review report, not a unified diff or merge instruction.
Review changes without a magic separator or misleading similarity score. Line alignment keeps later matches together; exact and intentionally ignored differences remain distinct.
