HTML Minifier

Minifying HTML shortens the document by dropping spaces and comments that browsers do not need. The tags and visible text remain. Keep an unminified copy for editing, and serve the shorter one.

What you get from HTML Minifier is concrete. Whitespace and comments are stripped from the paste. You can see bytes saved before you copy. The HTML stays in the browser. Read those results before you paste them into a template, a file, or a ticket. A copied mistake is harder to see later than a mistake still on this page.

A careful pass on HTML Minifier looks like this. Start with real input, not a placeholder you do not understand. Paste the HTML. Then check the middle of the form, because that is where optional fields change the output. Read the minified output. Finish by reading the whole result, not only the first line. Copy the minified HTML into the file you serve.

The limit is the part people skip on HTML Minifier. Match the output to the input you actually typed, then decide whether it belongs on the live site. Original size, minified size, space saved, and the reduction. You can see bytes saved before you copy.

A second reading of HTML Minifier is worth it because the first pass is easy to rush. Say out loud what the output is claiming. Whitespace and comments are stripped from the paste. You can see bytes saved before you copy. The HTML stays in the browser. Then say what it is not claiming. No. Size and output are computed in the browser. Original size, minified size, space saved, and the reduction. Keep the original for edits. Copy the minified HTML only into the file you serve. If those two speeches disagree, change the input or pick a different tool. HTML Minifier will not resolve the disagreement for you.

Read HTML Minifier once more as a single job. Part 1: Paste the HTML. Part 2: Read the minified output. Part 3: Compare original size, minified size, and the reduction. Part 4: Copy the minified HTML into the file you serve. You should be able to point at this in the result: Whitespace and comments are stripped from the paste. You should be able to point at this in the result: You can see bytes saved before you copy. You should be able to point at this in the result: The HTML stays in the browser. Does the minifier upload my HTML? No. Size and output are computed in the browser. What do the size figures show? Original size, minified size, space saved, and the reduction. Should I edit the minified copy later? Keep the original for edits. Copy the minified HTML only into the file you serve. Who is HTML Minifier for? HTML Minifier is for someone already doing developer tools work who needs compress HTML code to reduce file size and improve speed. Minifying HTML shortens the document by dropping spaces and comments that browsers do not need. The tags and visible text remain. Keep an unminified copy for editing, and serve the shorter one. The first field was filled with a real value: Paste the HTML. The result was read: Whitespace and comments are stripped from the paste. Optional fields were either filled or left empty on purpose. The copy went into the place the last step names. The boundary in the guide was respected before anything was published.

Keep HTML Minifier as this step only. When the job moves on, the CSS Minifier is the next page: CSS Minifier removes comments, spaces, and line breaks from CSS you paste and shows how many bytes that saves. The JavaScript Minifier covers a different piece of the same work: JavaScript Minifier strips comments and extra whitespace from script you paste and shows the size reduction.
