Find the small changes between two drafts

Use a line-by-line comparison to review a short draft or configuration snippet, and understand additions, removals, and whitespace changes.

Two drafts can look almost identical while saying something different. A comparison makes those edits visible without requiring you to read every line from memory. TinyDing’s Text compare works with pasted plain text and processes both versions in your browser.

Put each version in the right place

Paste the earlier version into Original text and the later version into Updated text. Select Compare texts.

Try this original:

Small tools.
Less busywork.
Done.

Then compare it with:

Small tools.
A little less busywork.
Ding, done!

The first line stays unchanged. The comparison marks the earlier second and third lines as removed and their replacements as added. Load example fills both editors with these versions.

Read the symbols as well as the colors

A line beginning with + was added in the updated version. A line beginning with − was removed from the original. Lines without either marker are unchanged.

Color makes scanning easier, but the symbols carry the same information. Copy comparison uses plain-text markers so the result remains understandable after you paste it into a message or note.

The comparison works at line level. Changing one word marks the whole earlier line as removed and the updated line as added. It does not highlight the specific characters that changed.

Check whitespace deliberately

Spaces and letter case count as differences. The lines done and Done do not match, and adding a space at the end of a line changes it.

The tool normalizes common line-ending formats before comparing. This prevents a Windows-style line ending alone from making every line appear different from the same text copied on another system. A final blank line can still be a meaningful difference.

If the result looks unexpectedly large, check whether your editor wrapped lines differently or inserted extra whitespace before interpreting the changes as rewritten content.

Know what a text comparison cannot review

A plain-text diff does not understand whether a sentence is correct, a contract is acceptable, or a code change is safe. It shows textual differences for you to assess.

Copying text from a PDF or word processor can introduce line breaks and discard formatting. This tool does not compare page layout, images, tables, tracked changes, or document metadata.

Repeated identical lines can allow more than one reasonable alignment. A displayed removal and addition does not necessarily mean that the writer performed those exact editing actions.

Finish with a manageable result

Each input is limited to 400 lines and 100 KB of UTF-8 text. For a larger codebase or document, compare the files in an editor designed for that task.

The tool does not save comparison history. Copy the result before leaving the page if you need a record, and avoid posting private material in public feedback. To review length after editing, open the Word counter.
