Does minifying Markdown break the rendered output?

No — as long as you keep the defaults. The tool never touches code blocks and preserves semantic whitespace (the blank line between two paragraphs). Aggressive options (Remove all blank lines, Collapse spaces) may affect rendering — use carefully.

Are code blocks preserved?

Yes. Content inside triple-backtick and triple-tilde fenced code blocks is never modified. The minifier only touches the text around them.

How much size reduction can I expect?

For heavily-whitespaced documents, 15-30%. For clean documents, 1-5%. The tool shows the exact before/after byte count and percent reduction.

Are HTML comments removed?

Yes, by default. Toggle off if you need to preserve notes.

Yes. Every tool on freemarkdowntools.com is free forever.
