Character counters

One page per platform, because no two platforms count a post the same way. A platform is listed here only where the dataset carries a body text ceiling for it.

Text and captions

Five small utilities for shaping a caption before it is posted: splitting a long post into a numbered thread, counting hashtags and mentions, converting case, copying an invisible character, and timing a script out loud.

• Thread splitter

  Split long text into a numbered stack of parts that each fit the character limit of a chosen network.

• Hashtag and mention counter

  Count hashtags and @mentions in a post and flag any hashtag that repeats.

• Case converter

  Sentence case, Title Case, UPPERCASE or lowercase, without touching a URL, hashtag or @mention.

• Invisible character copier

  Copy a zero-width or blank Unicode character, with an honest explanation of what it is for.

• Video script timer

  Estimate spoken duration and word budget for 15, 30, 60 and 90 second videos.

Text styles you can paste

These substitute Unicode look-alike characters for the letters you type, which is why the result pastes into a bio or a caption that has no formatting controls. None of them is a font file, and every one of them costs you something: styled text is read poorly by a screen reader and is not matched by search.

• Font changer

  Type once, see every Unicode text style, copy the one you want. Not a font file.

• Instagram fonts

  Styled text for an Instagram bio or caption, with the accessibility cost stated plainly.

• Discord fonts

  Styled text for a Discord name, status or message, and when to use markdown instead.

• Facebook fonts

• Cursive font generator

  Script and italic styles only, for when cursive is the thing you actually want.

Image and video specs

Every recorded upload limit in one place: file size ceilings, how long a video may run, how many files fit on one post and which formats are accepted.

• Image and video size limitsEvery recorded upload ceiling, video length and accepted format, one table per platform.
