Quickly filter text by character count range and clean up sentences or paragraphs that don't meet your length requirements.
Enter text and set a length range to see results
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
Paste multiline text, then set an optional minimum length, maximum length, or both. The filter keeps entire lines whose measured length falls within the range, including the minimum and maximum. It does not shorten lines or remove individual words. The output preserves the selected lines in their original order and shows total, kept, and removed line counts.
The measurement follows JavaScript string length, which counts UTF-16 code units. Most ordinary letters and common CJK characters count as one unit, while some emoji and less common Unicode characters use two. This is not a byte count, a grapheme-cluster count, or necessarily the number of characters a person sees as one symbol.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Each line is considered separately. Blank lines have length zero and can be retained by a range that includes zero.
Leave a limit empty to make it optional. Enter nonnegative values; if both are set, the minimum must not exceed the maximum.
Lines at either endpoint are included. Check total, kept, and removed counts, then copy the output if it matches your intended limit.
For a minimum of 3 and maximum of 6, “cat” and “planet” remain, while “hi” and “elephant” are removed. Their text is not edited.
Use cases
See how the tool fits into real work and everyday tasks.
Keep entries whose line lengths fit a submission limit, then inspect the retained text before pasting it into another form.
An editor can isolate short headings or longer descriptions by setting only the relevant minimum or maximum.
A class can compare visible symbols and measured code units, especially when emoji appear in example lines.
Q&A
Find concise answers to common questions and confusing cases.
No. It either keeps the complete line or removes it based on the selected bounds.
Yes. Leading, trailing, and internal spaces are part of the line string and count toward its length.
The filter uses JavaScript UTF-16 code units. Some emoji are represented by a pair of code units, so the measured length can be greater than one even though the emoji appears as a single symbol.
The range is invalid and the tool shows an error instead of a filtered result. Lower the minimum or raise the maximum.
Notes
Review scope, result limitations, and important precautions before use.
Different services may define a character limit by bytes, Unicode code points, or user-perceived grapheme clusters. This filter’s UTF-16 code-unit measure may not match a social platform’s or form’s counter, particularly for emoji and combined symbols. Verify the final text in the destination application when a strict limit applies.
