Punctuation Checker – Free Online Punctuation Fixer
About the Punctuation Checker
The Punctuation Checker scans your text specifically for punctuation errors, from missing commas to incorrect quotation marks and apostrophes. Each flagged issue includes a category label and a rule reference, so you can see exactly which punctuation rule was triggered before deciding whether to apply the suggested fix.
It supports eight English and European language variants, including English (US, UK, Australia, Canada, New Zealand), French, German, and Dutch. This tool focuses purely on punctuation, so for broader sentence-level corrections the Grammar Checker and Proofreading Tool cover grammar and style issues too, while the Spelling Checker handles misspelled words.
The BigToolSite Team tested this checker across all eight supported languages, common comma and apostrophe errors, and multiple simultaneous corrections to confirm suggestions apply accurately without disrupting sentence flow.
How to Use the Punctuation Checker
- Select your Language from the dropdown (English variants, French, German, or Dutch).
- Paste or type your text into the input box.
- Watch the live word counter to stay within the per-check word limit.
- Click Check Punctuation to scan your text for punctuation errors.
- Review each flagged issue with its category and rule tag, click Apply to accept the fix, or click directly on a highlighted section.
- Use Copy or Download to save either your original or corrected text.
Example Usage
Input: “Its a great day however I forgot my jacket at home.”
Output: The tool flags “Its” (missing apostrophe, should be “It’s”) and the missing comma before “however,” suggesting “It’s a great day, however, I forgot my jacket at home.”
This rule-tagged view is especially useful for writers who want to understand the reasoning behind each correction, not just apply it blindly.
