xIFr - Getting started

xIFr is a browser extension to show EXIF, XMP and IPTC metadata in jpeg images.

After having installed it in your desktop browser, you can use this page as an introduction to features of xIFr, or to test it works as expected... The first three cases below may seem a bit boring, because even though they technically are very different, with xIFr you just do the same every time. But some of the cases have helpful tips for your daily use...

Users of older Firefox versions (or browsers based upon that, like f.ex. Waterfox Classic) can install xIFr version 1.x which is compatible with Firefox 56 and up, but some features are only available with more recent xIFr and browser versions. xIFr version 2+ requires Firefox 78 or better.

Basic functionality

Basic functionalty

The photo to the left is an image embedded the most simple and straight forward way you can do it (using the "<img>" html tag). To open xIFr and see metadata of the photo, right click on the image and choose "View EXIF data" in the context menu...

Getting data from a background image

Deep Search

Photo to the right is not an ordinary html image element like above, but an image defined as a background style of another type of element. Many EXIF viewers cannot show you data for that. But with xIFr you usually don't care. Just right-click like before to open context menu and xIFr...

Getting data from an image behind a layer

Deep Search

The image to the left is sitting "behind" a layer. When right-clicking, you are clicking on a layer, not directly on the image. Some EXIF viewers cannot show you data for the image in such cases. But xIFr usually works fine. When right-clicking on [layer above] image, you can still select to open xIFr and see metadata of the image.

Notice, in a case like this (and cases like previous and next), you could say xIFr is kind of "guessing" which image you want to see data for, but it usually makes the right guess.

Ignore smaller images

Deep Search

Sometimes smaller images, logos or icons are placed above the "primary" image. At first if you try to see Exif data of the big photo to the right, xIFr will probably get data for one of the smaller thumbnails. That is because the smaller images are technically closer to the webpage-element your click was registered on. But xIFr has a trick... Hold down the Shift-key while selecting "View EXIF data" in the context menu, and xIFr will ignore smaller images.

When is an image considered "small"? The default limit is 30.625 "squarepixels" (equivalent to for example 175x175 pixels), but it can be configured on xIFr's Options Page.

Prefer jpeg version when multiple formats are offered

Deep Search

Sometimes webpages makes images available in multiple image formats, letting the browser choose which format to use. With modern browsers, in most such cases, for example avif and webp images will be preferred over jpeg format images. Current version of xIFr can however only parse meta-data from jpeg images. But xIFr will detect many of the cases where browser are presented with a choice, and try to find variant of jpeg-format to parse and show meta-data from.

To the left you likely see an avif or a webp format image. However if you open xIFr on it, it should detect and parse meta-data from a similar jpeg variant of the photo.

Avoid right-click hijacking

Browser functionality

This is not really a feature of xIFr, but a little browser tip... On some webpages the browser's default right-click context-menu is overriden by other functionality or just blocked. But with Firefox there's a simple way you usually can get it back. Just hold down the Shift-key while right-clicking on the image or page, and the browser's default context-menu should appear. Try right-clicking on the photo to the right - with and without holding the Shift-key...
