About the SEO Image Filename Generator
File names like IMG_4821.jpg tell search engines nothing. Google's image guidance recommends short, descriptive file names, and alt text remains one of the main ways to describe an image's content. This SEO image filename generator converts your descriptions, one per line, into lowercase, hyphenated file names without special characters, and drafts alt text for each.
Write each description as you would explain the image to someone who cannot see it, such as "red cotton kurta for women front view". Keep file names concise and avoid repeating the same keyword across every image. Review the draft alt text so it accurately describes each image in context; decorative images can use empty alt text. Descriptions are processed in your browser.
How to use it
- Enter a short description of each image, one per line.
- Review the generated file names and alt text drafts.
- Edit the alt text so it describes each image accurately.
- Rename your files before uploading and paste the alt text into your CMS.
Frequently asked questions
Do image file names matter for SEO?
Google's documentation says file names can give it light clues about an image's subject, so descriptive names are better than camera defaults. The effect is small compared with alt text and the page content around the image, but renaming is quick when you upload.
Should I use hyphens or underscores in file names?
Use hyphens. Google recommends hyphens to separate words in URLs, and image file names become part of the image URL. Hyphens are also easier to read than underscores or joined words. Keep names lowercase and avoid spaces, which become %20 in URLs, and non-essential words that only make the name longer.
How long should alt text be?
There is no fixed limit, but alt text works best as a concise, accurate description of what the image shows, usually a short sentence. Include a keyword only if it genuinely describes the image, and avoid starting with phrases like "image of".
