My Free AI Image Caption Generator: Write Perfect Captions Instantly With This Powerful Image to Caption Writer Tool
Need captions for your images? This AI image caption generator lets you instantly write accurate, compelling captions for all kinds of images. Whether you want a social media caption or a caption to use within a blog post, you’ll get a range of options to choose from in just seconds.
Having good image captions is important in so many contexts. If you’re posting an image to your Instagram account, for instance, you’ll want an engaging caption to go along with it. And even if you think the image stands alone, a descriptive caption can help make it more accessible (e.g. to visually impaired users).
Because search engines can’t “read” images in the same way as text, captions can also boost your SEO, as well as giving readers more context about your images.
Tip: Want to add alt text to your images? This is a great SEO practice and we have a special image alt text generator you’ll love.

AI Caption Generator FAQs (Frequently Asked Questions)
Got questions about the caption generator—or about writing captions in general? Here’s what you need to know.
Can I Use the Caption Generator to Create Alt Text?
If you want, you can use the caption generator for writing alt text. But a better option is to use the alt text generator instead, as this is specifically designed for high-quality, optimized alt text.
Can I Use the Caption Generator to Create Alt Text?
If you want, you can use the caption generator for writing alt text. But a better option is to use the alt text generator instead, as this is specifically designed for high-quality, optimized alt text.
Can I Put in a URL Instead of Uploading an Image?
No. If your image is already online (e.g. in a published blog post) then you need to save it to your computer/device and then upload it as the input image.
Why Do Images Need Captions?
A good image description is important for both users and search engines. Not everyone will be able to see the image—and even when users can view it, your caption can give extra meaning, context, and emotion to the image.
Relevant captions will always make your image more useful (and more search engine friendly). It’s well worth taking a few extra seconds to add a caption to your image.
How Should I Use Images on My Blog for Good SEO?
For SEO purposes, all your images should have alt text. It’s also a good idea to resize and compress your images before uploading them, so that they’re as small as possible (while retaining good quality). That way, your page will load faster—an important ranking factor.
How Does the Caption Generator Understand the Image?
You might be astonished at how well the caption generator can interpret whatever image you give it. Maybe you’re curious about the underlying technology and AI algorithms.
You’re probably already familiar with artificial intelligence (AI), and the caption generator uses a type of AI called “computer vision” which lets it recognize objects in images.
The caption generator is powered by deep learning models. These include CNNs (convolutional neural networks), which are essentially used for image classification. The models also include RNNs (recurrent neural networks which use technologies like LSTM, long short-term memory, to “remember” previous information). These models are trained (machine learning) on huge datasets of images plus captions, so they can then act as a “decoder” for images.
When it comes to creating the caption, the Caption Generator uses Natural Language Processing (NLP) to write a suitable caption for you that’s true to the image.
