Text Truncator

Cut text down to a fixed length without uploading it anywhere. Everything runs locally in your browser.

Features

Count by characters, bytes, words or lines — characters are counted as code points, so an emoji counts as one. Byte mode measures UTF-8 and never cuts a multi-byte character in half.
Keep the start, the end or both ends — head keeps the first N units, tail keeps the last N, middle splits the budget between the two ends.
Custom marker — replace … with any text, or leave the field empty for a plain cut.
Marker counts toward the limit — a limit of 160 really returns at most 160 characters, which is what meta descriptions and CMS fields require.
Word mode — cut on word boundaries and drop the separator in front of a kept tail, so the result stays readable.
Counts — see the original length and the resulting length side by side.
Export — copy the result, move it into the input to keep trimming, or download it as a .txt file.

Nothing is truncated when the text already fits the limit, and no marker is added in that case.

All processing stays on your device; no data leaves the browser.
