Why use text padding?
Prototype fixed-width lines, pad numeric-looking columns with zeros, or add leading spaces before pasting into terminals and markdown—all without a desktop editor.
Benefits
- Per line: newline-separated rows keep their own lengths.
- Target width: only fill up to a column width when lines are short.
- One character: predictable repeats (space, 0, •, etc.).
- Live: output tracks every change.
- Private: client-side only.
How it works
The tool splits on line breaks, computes how many pad characters to add for each line from your mode and settings, then rejoins with newlines.
Features
- Left / right / both: mirror common padding directions.
- Slider (0–100): fixed total pad amount when target width is off.
- Target width: overrides the slider when > 0.
- Pad char: one Unicode code unit per slot (typical ASCII).
- Copy: grab the textarea in one click.
When to use
Teaching alignment, quick demos, log prefixing, or cleaning up uneven paste before another tool.
Ideal use cases
- Mock columns: monospace preview in chat or notes.
- Zeros: informal fixed-width numbers (verify for real systems).
- Indent bursts: left pad with spaces in bulk.
- Uniform width: target length for short labels.
- Drafting: iterate before scripting.
Facts
Behavior notes.
Key points
- Target width 0 means “use slider length”; any value > 0 switches to width mode.
- Moving the slider resets target width to 0 in the UI (same as current app behavior).
- Very long lines wider than the target get no extra padding from width mode.
- Combining characters and wide emoji may count differently than you expect.
- Plain text only—no HTML/CSS tables.
Best practices
Avoid surprises.
Quality considerations
- Verify padded output in the final font (monospace vs proportional).
- For strict numeric fields, use your system’s formatting rules.
- Preview with sample lines before bulk paste.
- Keep an original copy if padding is hard to reverse.
- For RTL scripts, check layout in the destination app.
When not to use
- When you need HTML tables, CSV quoting, or real databases.
- When variable-width typography must stay exact.
- When security or compliance forbids client-side tools.
Limitations and compatibility
One pad character; lines split on \n; copy only. Requires JavaScript.
Text padding runs fully in your browser with no server upload; padded output updates instantly as you change side, width, or pad character.
Frequently asked questions
Is text padding free?
Yes. Processing runs in your browser. No registration or upload.
What is target line width?
When set to a number greater than zero, each line gets enough padding so its length (before padding) plus added characters reaches that width—only if the line is shorter. Set to 0 to use the slider count instead.
Can I use zeros or symbols as the pad?
Yes. One character only (the field accepts a single glyph). Spaces are the default.
How does “both sides” work?
Half the pad length (rounded down) goes on the left and half on the right. If the length is odd, one extra pad character is added on the right.
Is my text secure?
Yes. Everything stays on your device.
Does this replace real monospace layout?
No—it is a quick plain-text helper. For production tables or HTML, use the right format and fonts.
