Multilingual interface designer
Keep emoji families and accented characters intact in short labels.
Paste mixed Unicode text, set a grapheme budget and inspect retained characters.
No partial surrogate or combining sequence is emitted.
Text Truncator
Shorten text at complete Unicode grapheme boundaries. Include the marker in a character or byte budget, keep either end or both, then preview and export.

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
Shorten text at complete grapheme boundaries under a marker-inclusive grapheme, UTF-16 or UTF-8 budget while retaining the chosen ends.
Developer enforcing a byte limit
Fit a preview within an explicit UTF-8 budget.
Choose UTF-8 bytes, use a short marker, inspect original/output sizes and test a too-large marker.
Output stays within budget or returns a clear refusal.
Mobile content editor
Compare beginning, ending and middle excerpts without losing source.
Choose marker positions, clear and undo source, restore the prior successful run and export.
Source remains available and the marker is included in the stated limit.

How it works
Updated August 2026Complete-character boundaries
Intl.Segmenter supplies the current runtime’s grapheme boundaries. UTF-16 and UTF-8 budgets still cut only between whole graphemes; unsupported segmentation fails explicitly.
Marker-inclusive budget
The budget ranges from 0 to 100,000 selected units and includes the marker. End keeps a prefix; Start keeps a suffix; Middle gives the prefix the rounded-up half of remaining capacity, then fills available space.
Exact limits, contextual meaning
No normalization or whitespace trimming is applied. Runtime Unicode versions may differ, and character counts do not guarantee pixel width, readability or a platform-specific limit.

Common Mistakes to Avoid
Common Mistakes to Avoid
Adding dots after a full-length slice
The marker consumes part of the budget; it is not appended beyond the stated maximum.
Treating characters as pixels
A grapheme is not a fixed visual width or a word. Check the final layout and meaning before publishing.
FAQ
Yes. It is only added when truncation is needed. If it cannot fit, shorten or clear the marker instead of silently exceeding the limit.
A whole grapheme may require several UTF-16 units or UTF-8 bytes. The tool leaves spare capacity instead of splitting that grapheme.
Choose Start to put the marker before retained suffix text, End for a retained prefix, or Middle for both ends when space allows.
Yes. Empty input is valid. To truncate non-empty text to a zero budget, clear the marker. A valid empty result can be downloaded as a zero-byte file.
No. Select the metric required by your destination and verify it there. Browser Unicode segmentation versions and platform rules may differ; byte counts are UTF-8 without a newly added BOM.
