Generate SEO-friendly image file names and alt text from a short description — free online.
About
Suggests an SEO-friendly filename and alt text for an image from a short description you provide.
Bloggers and web editors use it to quickly get a sensible filename and alt text instead of leaving an image as "IMG_1234.jpg" with no description, while SEO practitioners use it as a fast starting point before fine-tuning by hand. It's one of many free SEO tools on Toolapt, and like every tool here, it's free to use with no sign-up and no limit on how many times you run it.
Examples
3 worked examples
Uploading "Strawberries Market.jpg" (800 × 600, 0.20 MB) flags 2 issues — a space and uppercase letters in the filename — and describing it as "fresh strawberries at a farmers market" suggests fresh-strawberries-at-a-farmers-market.jpg with matching alt text.
A 3000 × 2000 snowy-valley.jpg has a clean filename but is flagged for its size (1.71 MB, over 300 KB). Described as "snow-covered mountain valley", it downloads as snow-covered-mountain-valley.jpg — still 1.71 MB, so run it through Image Compressor too.
IMG_1234.jpg is flagged as generic and uppercase; described as "lioness looking at the camera", it becomes lioness-looking-at-the-camera.jpg with descriptive alt text search engines can read.
FAQ
Quick answers to common questions about the Image SEO Optimizer.
It takes a short description of an image you provide and suggests an SEO-friendly filename and alt text to use when you publish it.
Yes. It's free, with no sign-up, no watermark and no limit on how many times you use it.
Yes. The image and description you provide are processed entirely on your own device — nothing is uploaded to a server.
The tool turns your description into a properly formatted filename and alt text — it doesn't try to guess what's in the photo automatically, so the suggestion is only as accurate as the description you give it.
Lowercase words separated by hyphens, describing what the image actually shows, instead of a generic camera-generated name like IMG_1234.jpg — that helps both search engines and humans understand the file at a glance.
It's a solid starting point, but always check that the suggested alt text accurately and specifically describes your actual image before publishing it.
Yes. The page is fully responsive and works on mobile, tablet and desktop browsers alike.
It generates suggestions from the description you type rather than analyzing pixel content, so the result is only as good and as specific as what you describe.
