Image SEO Tagger

Image SEO means giving search engines words that describe a picture: a descriptive file name, alt text on the page, and a title, caption and keywords stored in the file. Google Images also reads the creator, credit line and copyright notice from the file.

How to add SEO metadata to an image

  1. Drop your images

    Add one image to see and edit what it already holds, or several to give them all the same keywords, caption or credit.

  2. Write the title and alt text

    Describe the image in plain words. A counter shows when the alt text passes 125 characters, the usual guideline for keeping it short.

  3. Download and publish

    Download the tagged file, renamed from the title, and paste the HTML snippet into your page so the alt text and size are set there too.

Why use this tool

Alt text inside the file

Alt text is saved in the standard accessibility field for images, so a site builder or media library that reads it can fill in the alt attribute for you.

Search-friendly file names

The download is renamed from the title, so "Red bike at sunset" becomes red-bike-at-sunset.jpg. A batch is numbered -1, -2 and so on. The rename can be turned off.

Ready-made HTML

For a single image, copy an img tag with the file name, alt text, title, width and height filled in. Setting the size stops the page jumping while it loads.

Read by common platforms

Title, caption, keywords and credit are written to the XMP fields and, for JPG, the IPTC fields that WordPress, stock sites and photo apps read on upload.

Images stay on your device

Files are tagged in your browser and never uploaded. The photo reader downloads once, about 7 MB, and is reused for the rest of the visit.

About this tool

Search engines cannot see a picture, so they rely on the words around it. The ones that matter most are on the page: the file name and the alt attribute. The file itself can also carry a title, a caption, keywords and a credit line, and those travel with the image wherever it is uploaded. This tool writes all of them in one pass. Nothing is generated for you; the words are yours.

Values are stored in the formats readers actually use. The title, caption and keywords go into XMP, and for JPG files also into the older IPTC fields, which WordPress uses to fill in the title and caption of an uploaded image. Alt text goes into the accessibility field defined by the IPTC photo metadata standard. Google Images shows the creator, credit line and copyright notice from these fields next to a picture.

With one image, the form starts with what the file already holds, the download is renamed from the title, and an HTML snippet with the width and height is ready to copy. With several, only the fields you fill in are written to every file, and the names are numbered. To edit the date, camera, or copyright as well, use the EXIF editor. To remove camera details and location before publishing, use the EXIF remover or the metadata stripper.

Frequently asked questions

How does the image SEO tagger work?
It reads the metadata already in your image, lets you edit the title, alt text, caption, keywords and credit, and writes them back into the file. The image data is copied unchanged, so the picture looks exactly the same.
Are my images uploaded?
No. Images are read and tagged in your browser and never leave your device. The photo reader, about 7 MB, is downloaded once the first time you use it.
Does alt text in the file replace the alt attribute?
No. Search engines and screen readers use the alt attribute in your HTML. The copy inside the file is for site builders and media libraries that can fill the attribute from it. Use the HTML snippet to set it on the page.
Does Google read image metadata?
Google Images reads the creator, credit line and copyright notice stored in a file and can show them next to the image. Rankings depend mostly on the page: the file name, alt text and the text around the image.
Which files can I tag?
JPG, PNG, WebP and HEIC images, one or many at once. Images are processed one at a time, so large batches work but take a little longer, and very large files are limited by the memory of your device.
