Google reads image filenames as ranking signals. A file named IMG_4829.jpg tells search engines nothing; blue-running-shoes-men.jpg tells them exactly what the image shows. Type your keyword phrase and this free SEO image filename generator builds a search-friendly name - lowercase, hyphen-separated, stop words stripped - plus a ready-to-paste alt text suggestion.

Type the keyword phrase that describes the image. The tool handles the rest.
Frequently asked questions
Do image filenames really affect SEO?
Yes, modestly. Descriptive filenames help Google Images understand what a picture shows, which supports image-search rankings. They work best combined with good alt text, compression and relevant surrounding content - no filename alone will rank a page.
Should I use hyphens or underscores in image filenames?
Hyphens. Google treats hyphens as word separators, so blue-running-shoes reads as three words. Underscores join words into one token, which search engines parse less reliably.
What are stop words?
Stop words are common filler words search engines largely ignore: the, and, for, with, of and similar. Removing them keeps filenames short and keyword-dense without losing meaning.
Is this SEO filename generator free?
Yes. Generate unlimited filenames and alt texts with no signup and no caps. Everything runs in your browser.
Does it rename my image file?
No. It generates the name text for you to apply yourself. For long lists of names, pair it with the Bulk Filename Generator on this site.
How should I name images for SEO?
Short answer: Describe the image with your target keyword in 3 to 6 lowercase words joined by hyphens, for example handmade-ceramic-coffee-mug.jpg. Remove stop words, keep it under about 60 characters and match the real file extension. Then add a natural alt text describing the same image for screen readers and extra ranking context.
Avoid keyword stuffing: one clear phrase beats a filename crammed with every synonym you can think of.
What is the best image filename format for Google?
Short answer: The best format is lowercase, hyphen-separated words with no spaces, accents or special characters, ending in the true extension (.jpg, .png, .webp). Camera defaults like DSC_0042.jpg and exports like final-v2-FINAL.png waste the ranking signal that a descriptive name provides. Shorter names also survive CMS truncation and display cleanly in image search results.
This tool enforces that format automatically: paste a phrase and it outputs a name that follows every rule.
Should alt text match the filename?
Short answer: They should describe the same image but not be identical. Use the filename for the keyword-dense slug (blue-running-shoes-men.jpg) and the alt text for a natural sentence (Blue running shoes for men on a track). That covers both the crawler signal and accessibility without looking stuffed.
The tool generates both at once so they stay consistent with one click each.
