Remove Empty Lines

Remove blank lines quickly with PicoToolkit

Remove empty lines (zero-character lines) from any list or text block in one click. PicoToolkit’s Remove Empty Lines is focused and predictable: it deletes only truly empty lines. Use other PicoToolkit tools if you need to trim or modify content first.

How to use

• Paste or type your text into the editor above.
• Optional — trim spaces: select Remove → Trim spaces to remove spaces from the ends of each line if you want whitespace-only lines to become empty.
• Click Remove → Empty lines to delete lines that contain zero characters.
• Copy the cleaned text back to your workflow.

Behavior & exact rules

• Definition of empty: a line must contain zero characters to be removed. Lines with spaces, tabs, or other whitespace characters are not considered empty unless trimmed first.
• Only deletion: the tool removes lines; it does not trim, renumber, reorder, or otherwise change non-empty lines.
• Preserves order: remaining lines keep their original order and content.
• Idempotent: running Remove Empty Lines again has no further effect once all zero-character lines are removed.
• Chaining: use Trim spaces and other PicoToolkit tools before or after removal to achieve the exact result you need.

Examples (copyable)

1) Simple blank lines

Input:
apple

banana

cherry

Output after Remove Empty Lines:
apple
banana
cherry

2) Lines with spaces (not removed unless trimmed first)

Input:
first line
     
second line
		← (tab characters)

Output after Remove Empty Lines (no trim step):
first line
     
second line
		← (tab characters)

If you want these removed: run Remove → Trim spaces, then Remove → Empty lines.

3) CSV-style rows with occasional empty rows

Input:
id,name,city

1,Alice,Seattle
2,Bob,Portland

3,Clara,Boston

Output after Remove Empty Lines:
id,name,city
1,Alice,Seattle
2,Bob,Portland
3,Clara,Boston

Common use cases

• Clean exports from other tools where blank rows remain.
• Prepare lists for sorting, numbering, or deduplication.
• Remove accidental empty lines after HTML stripping or find-and-replace operations — see HTML Stripper.

Tips & edge cases

• Whitespace-only lines are not removed automatically. To clear them, run Remove → Trim spaces first (see the Trim tool link above).
• If you need to remove lines matching a pattern or specific phrase, use Remove Lines Containing instead.
• To preserve original numbering after cleaning, chain tools: remove line numbers, trim/remove empty lines, then add line numbers back with Add Line Numbers.
• Make a copy of your input before running bulk edits if you may need to undo changes.

Related tools

• Trim spaces — remove leading/trailing whitespace from each line.
• Remove Lines Containing — filter out lines matching a phrase or pattern.
• Add Line Numbers To Text — re-number lines after cleanup.
• HTML Stripper — remove HTML tags (often leaves empty lines behind).

FAQ

Will lines that contain only spaces or tabs be removed?

No. Remove Empty Lines deletes only zero-character lines. To remove whitespace-only lines, first run Remove → Trim spaces to convert them to empty lines, then run Remove Empty Lines.

Does this tool change or reorder non-empty lines?

No. The tool only removes empty lines. Content, whitespace inside non-empty lines, and line order are preserved.

Can I upload a file?

The editor accepts pasted or typed text in the browser. For large inputs, consider splitting into smaller chunks if you encounter browser limits.
