Free Social Media Tools: Hashtags and UTM Links for Your Posts

Social media posts often need two small jobs done before publishing: finding hashtags that fit the topic, and building a link you can track. This guide covers two free tools that do those jobs in your browser: Hashtag Generator and UTM URL Builder.

Both tools covered in this guide are free with no sign-up. Each tool page shows its own steps, and this guide follows them. A third tool, QR Code Generator, is mentioned at the end as a related tool, since it already links to another guide.

Tools in this guide

• Hashtag Generator – generate hashtags from a topic or keyword, with an optional niche.
• UTM URL Builder – add UTM tracking parameters to a destination URL.
• Related tool: QR Code Generator – turn a URL or short text into a QR code image.

Hashtag Generator

Hashtag Generator creates hashtags from a topic or keyword you type. It is keyword-based, using simple deterministic word-combination rules: it is not AI-generated, and it does not check trending topics or connect to a social platform or external API.

How to use it:

1. Type a topic or keyword.
2. Optionally choose a niche: None – keyword-based only, General, Business, Fashion, Fitness, Food, Travel, Tech, or Music.
3. Click “Generate Hashtags”.
4. Copy the result.

Use this tool when you are preparing a post and want a set of hashtags related to its topic, for example for a business update, a fitness post, or a travel photo. Picking a niche narrows the suggestions to that area; leaving it at None keeps the result keyword-based only.

UTM URL Builder

UTM URL Builder adds UTM tracking parameters to a destination URL, so visits from a post can be identified in analytics. It preserves existing query parameters and properly URL-encodes values, and the tracking URL updates live as you type. It does not shorten the URL.

How to use it:

1. Enter the destination URL.
2. Fill in utm_source, utm_medium, and utm_campaign. These are described as required for most analytics tools.
3. Optionally add utm_term and utm_content.
4. Copy the generated tracking URL.

Use this tool when you share a link in a post and want to know which post, platform, or campaign brought the visit. For example, use one campaign name for a product launch and different source names for each platform you post on.

Which tool should you use?

• To get hashtags for a post: Hashtag Generator.
• To build a trackable link for a post: UTM URL Builder.
• To turn a link into a scannable code: QR Code Generator (related tool).

The two covered tools work well together: generate hashtags for the post text, then build a UTM link for the link in the post, so the post is both discoverable and trackable.

Practical tips

• Type the main topic or keyword first, then try a niche if the first result does not fit.
• Copy the hashtags and the tracking URL before leaving the tool page, so you do not have to generate them again.
• Use the same campaign name across posts in one campaign, so their visits group together in analytics.
• Check the generated tracking URL before sharing it, and keep the original destination URL unchanged apart from the added parameters.
• For a QR code to go with a post, use QR Code Generator as a related tool.

Limitations to keep in mind

• Hashtag Generator does not check trending topics, so it cannot tell you which hashtags are popular right now.
• It does not connect to a social platform, so it cannot post for you or check how a hashtag performs.
• UTM URL Builder does not shorten a URL, so the tracking link will be longer than the original.
• UTM parameters only help if the destination site’s analytics reads them; the tool itself does not report visits.
• QR Code Generator is mentioned here only as a related tool, since it already links to another guide.
