Resize your images, generate SEO-friendly filenames, and write alt text automatically. Upload a photo, paste an image description or a link, then download.
Sluggify is a free, AI-powered tool for renaming and resizing images, and for writing alt text. It's built for SEO practitioners and content teams.
If you publish articles with stock photos or property images, you know the drill. Download the image. Resize it. Compress it. Rename it with something search-friendly. Write the alt text. Then do it again, dozens of times a day.
Sluggify automates all of it. Drop in your images, paste the image description or the source link, and get an SEO-friendly filename plus ready-to-use alt text in seconds. It's powered by AI and runs entirely in your browser.
Descriptive, hyphenated filenames and well-written alt text are both part of Google's official image SEO guidance. Neither one is a major ranking factor by itself. But they're free, they're easy, and most teams skip them simply because doing them by hand doesn't scale. That's the gap Sluggify fills.
Resizing, cropping, and AI calls all happen locally in your browser. No images are uploaded to any server we control. You bring your own free Groq API key, or a paid Anthropic key for higher-quality results. There's no subscription and no hidden cost.
