Paste a caption and see how many hashtags it carries, which ones repeat or won't link, and whether it clears each network's rules — including Instagram's five-hashtag cap introduced in December 2025. Free, instant, and runs entirely in your browser.
LIVE COUNTER
Paste the whole caption, hashtags included. The counter separates unique tags from repeats, flags tags that won't become links, and checks the total against each platform's published limit.
Instagram capped posts and Reels at five hashtags in December 2025, down from thirty. Its own framing: tags help search, not reach — a few precise ones beat a long generic list.
Threads
0 / 1Threads uses topic tags rather than hashtags, and allows exactly one per post.
YouTube
0 / 60Up to three hashtags show above the title; past 60 in the description YouTube ignores all of them.
TikTok
no capNo published hashtag cap — they share the 2,200-character caption budget with your copy.
X / Twitter
no capNo published cap, but every hashtag spends part of the 280-character post.
No published cap. LinkedIn's own guidance favours a small, specific set over a long list.
Bluesky
no capNo published cap; hashtags count against the 300-character post like any other text.
A thirty-hashtag block that was standard on Instagram until December 2025 now breaks its five-tag cap, is twenty-nine tags past what Threads accepts, and can spend more characters than a Bluesky post has in total. AnySync writes a per-platform tag set sized to each network from a single upload, so one caption doesn't have to satisfy seven sets of rules.
Drop in the full caption with its tags. Nothing is uploaded — the parsing runs entirely in your browser.
Unique tags, repeats, digits-only tags that won't link, stray hash symbols, and the characters the block spends.
Instagram's five, Threads' one topic tag, YouTube's sixty-hashtag cutoff — plus the character budgets that act as the real limit elsewhere.
This counter tells you where a caption breaks a rule. AnySync writes a caption that never does.
AnySync generates a tag set sized to each network from one upload, instead of pasting the same block everywhere.
Captions are generated to fit each platform's current limits, so posts don't get truncated or tags silently ignored.
Brand voice and workspace settings shape the copy, so the tags read as part of the caption rather than a block bolted on the end.

In the product
Five. Instagram announced on 19 December 2025 that it would limit the number of hashtags you can include in a caption for a post or Reel to five, down from the long-standing thirty, and rolled it out gradually from there. It is a cap on what you can put in the caption, not a reach penalty for going over — and Instagram's own framing is that tags help search rather than reach, so a few precise ones beat a long generic list. Many hashtag tools still quote the old thirty.
One. Threads uses topic tags rather than hashtags and permits exactly one per post, deliberately, to keep topic feeds from being flooded.
Yes. Up to three hashtags from the description appear above the video title, and if a video or playlist carries more than 60 hashtags, YouTube ignores every hashtag on it.
None of them publish a hard hashtag cap. The real constraint is the character budget — hashtags spend the same 280 characters on X, 300 on Bluesky, 2,200 on TikTok, and 3,000 on LinkedIn that your copy does, which the counter tracks.
Tags made only of digits aren't linkable on Instagram or X, repeated tags spend characters without adding reach, and a hash symbol not followed by a letter, number, or underscore never becomes a link at all.
Yes. It's free, needs no sign-up, and runs entirely in your browser — your caption never leaves your device.
