Do I need to include the # symbol?

No. You can type words without #, and the tool adds it automatically. Mixing tagged and untagged entries works fine too.

Are hashtags with different capitalization treated as duplicates?

By default, #React and #react are treated as the same tag. Turn on "Case sensitive" if you want to keep both.

How many hashtags does Instagram allow?

Instagram allows up to 30 hashtags per post. The tool shows the count so you can adjust easily.

How many hashtags should I use on X (Twitter)?

2 to 3 is recommended. Too many can hurt readability and may look like spam.

3 to 5 hashtags is ideal for TikTok. Focus on core keywords for better visibility.

Can I clean hashtags in any language?

Yes. The tool handles any characters — Latin, Korean, Japanese, emoji, and more.

What sorting options are available?

Original order, alphabetical, and by length. Choose whichever suits your workflow.

Are my files sent to a server?

No. Everything is processed in your browser. Nothing you type is sent to a server.

Can I separate input with commas or line breaks?

Yes. Spaces, commas, and line breaks are all recognized as separators. Paste in any format.
