AI Alt-Text Generator (2026)
Upload any image and get SEO-friendly alt text under 125 characters, plus a longer description, a clean filename, and a title attribute. AI vision reads the image and writes accessible, search-friendly copy — add a target keyword and it weaves it in naturally.
What makes good alt text?
Good alt text describes what the image shows and why it's on the page, in one concise sentence under 125 characters. Skip filler like "image of" — screen readers already announce it as an image. Describe the content directly: the subject, what it's doing, and any text or detail that matters to the page. If the image is purely decorative, leave the alt empty rather than padding it.
Why alt text matters for SEO
Alt text is how Google reads an image. Clear, descriptive alt text earns Google Images traffic and reinforces what a page is about, so it lifts the page's relevance for its target query. It's also an accessibility requirement, and accessible pages tend to rank better. The catch: keyword-stuffed alt text reads as spam and can hurt you, so describe the image honestly and let the keyword appear only where it genuinely fits. Once the page is written, check the search listing with the SERP snippet preview and confirm your structured data with the schema markup generator.
How to use the generator
Upload a PNG, JPG, WebP, or GIF up to 4MB. Optionally add a context note or your target keyword so the output reflects how you'd describe the image on the page. Click Generate and you'll get four copy-ready fields: the alt attribute, a longer description for captions, a clean kebab-case filename, and a title attribute. Copy each with one click. It's one of the free SEO and ad tools from Ryze AI.
Frequently asked questions
What makes good image alt text?
Good alt text describes what the image shows and its purpose in one concise sentence under 125 characters. It avoids redundant phrases like 'image of', describes the content directly, and works in the context of the page rather than just listing objects.
How long should alt text be?
Aim for under 125 characters. Most screen readers comfortably read that length, and search engines weight the first words most. If the image needs more explanation, put the detail in surrounding text or a caption, not the alt attribute.
Does alt text help SEO?
Yes. Alt text helps Google understand images, which drives Google Images traffic and reinforces page relevance. It also improves accessibility, and accessible pages tend to rank better. Descriptive, honest alt text helps; keyword-stuffed alt text can hurt.
Should I add my keyword to the alt text?
Only if it fits naturally. Add the context or target keyword in this tool and it weaves the term in where it genuinely describes the image. Forcing a keyword into every image's alt text looks like spam and can be penalized.
Is this alt text generator free?
Yes. Your first image is free with no signup. Generating alt text for more images asks for an email so you can run it across a whole catalog.
