This tool adds a real line through each character using a Unicode combining character, so the strikethrough effect works even in apps that don't have a built-in strikethrough formatting option.
A combining character (U+0336) is attached invisibly after each letter, and font renderers draw it as a line running through the character before it. Because it's attached per-character, it works consistently regardless of the surrounding app's formatting support.
Apps that do offer strikethrough (like some chat apps using markdown, e.g. ~text~) only apply it within that specific platform — the formatting doesn't survive being copied elsewhere. This Unicode version travels with the text itself.
Crossing out a price, marking something as outdated in a bio, or making a joke by 'retracting' part of a sentence.
Almost everywhere, since it's a standard Unicode combining character rather than app-specific formatting — a small number of very old systems may not render it correctly.
Direct combination isn't offered here, but you can convert to bold first, then run that result through the strikethrough tool for a layered effect in apps that preserve both.
Yes — every character, including spaces between words, gets the combining line applied for a continuous strikethrough effect.
