YouTube Tag Splitter — Copy Tags One by One on Mobile

The YouTube app makes you add tags one at a time, and pasted lists turn into one broken tag. Paste your whole tag set once, then tap Copy Next to feed them in individually — the tool tracks what you've already used so you never lose your place mid-list.

Tip: tap any tag to copy just that one. Tags in red push you past YouTube's 500-character limit and will be cut off — remove a few with the × on each chip. Some app versions do split a pasted comma list — try Copy all first; if it becomes one big tag, switch to Copy Next.

Why entering YouTube tags on mobile is so painful

On desktop you can often paste a whole comma-separated tag list into YouTube Studio and it splits into chips. The mobile app doesn't behave that way: it treats your pasted list as the text of a single tag, so a careful set of fifteen keywords becomes one useless tag reading "travel, food, vlog, …". The only reliable method is entering tags one at a time — copy a tag, switch to the app, paste, switch back, repeat. Doing that by hand from a notes app means fiddly text selection on every single tag, and it's easy to lose track of which ones you've already added.

This tool removes the friction from that loop. Paste your tag set once and it's cleaned instantly: duplicates removed, stray hashes stripped, whitespace tidied, and everything de-cluttered into tappable chips. The Copy Next button copies the next un-used tag and shows you the one after it, so you settle into a rhythm — tap, switch, paste, switch, tap — without hunting for your place. Each copied tag is checked off and the progress bar fills, so if you get interrupted you can see exactly how far you got. When you return to this tab from the YouTube app, the button pulses to cue your next copy.

It also keeps you inside YouTube's rules: tags are capped at 500 characters including commas, and the live budget bar flags any tags that spill past the limit so you can trim before they get silently truncated. A hashtag mode is included for when you're preparing clickable hashtags for your title or description instead of field tags — though for the tag field itself, plain tags without a # are correct.

Frequently Asked Questions

How do I add lots of tags to a YouTube video on mobile?
The YouTube app makes you enter tags one at a time, and pasting a comma-separated list often becomes a single broken tag. Paste your whole tag set into this tool once, then tap Copy Next to copy each tag in turn — switch to the YouTube app, paste, switch back, tap Copy Next again. The tool tracks which tags you've already copied so you never lose your place.
Why won't my pasted tags split in the YouTube app?
The YouTube mobile app treats a pasted comma list as the text of the current tag chip rather than splitting it, so "travel, food, vlog" becomes one tag called "travel, food, vlog". Copying and pasting tags individually is the reliable way to enter them, which is exactly what this tool speeds up.
What is YouTube's tag character limit?
YouTube allows up to 500 characters of tags total, including the commas between them. This tool shows a live character count and flags any tags that push you past 500 so you can trim before posting.
Should YouTube tags have a # in front?
No. Tags in the YouTube tag field should be plain words or phrases without a #. Hashtags (with #) belong in your title or description, where they become clickable. This tool strips # from tags by default, and has a separate hashtag mode if you're preparing hashtags instead.
Does the tool know which tags I've pasted elsewhere?
It tracks every tag you copy from the tool and marks it as done, which is what keeps your place during mobile entry. It can't see what you paste inside the YouTube app — the checkmarks reflect copies, not pastes — but in practice copy and paste happen together, so the progress stays accurate.
Is anything I paste sent to a server?
No. All splitting, cleaning and copying happens locally in your browser. Nothing you paste is uploaded, stored, or transmitted anywhere.
