No description (alt text)
A short text that screen readers read aloud and that shows when a picture fails to load. Missing, or too generic to help, is reported. A purposely empty one on a decorative image is correct and left alone.
Image Doctor, included in every plan
Your images have a few things to confess. Image Doctor listens.
Images are the heaviest, most overlooked part of most websites. Missing descriptions leave screen-reader users with nothing, giant files slow every phone, and broken pictures look like a house with a missing window. Image Doctor lists every image on your pages, shows what is wrong with each one and exactly how to fix it, and checks again after you do.
- Every image, every pageOne list, with each place an image is used.
- Evidence, not a scoreWhat we measured, and the exact step to take.
- Export and recheckA spreadsheet for your team, and a fresh scan to prove it is fixed.

Add width and height so the browser reserves the space.
What it finds
Six kinds of image problem, each in plain English
Broken images
Addresses that answer "not found" or an error, with every page that uses them.
Heavy files
Photos that are far larger than a page needs, measured in kilobytes, with advice on resizing and newer formats.
Pages that jump
Images with no width and height, so the page moves while it loads.
The main image loaded late
A big image near the top set to load lazily, which delays what visitors see first.
One image, many uses
The same picture with different descriptions on different pages, listed so you can check each one fits.
What works today, in every plan
The Images screen is on every verified website, next to Site Health. At the end of every full scan Crawvix builds a list of the images on the pages it read, and shows each problem with the evidence and what to do. You can export the list as a spreadsheet. These image checks also run in every full scan, with fix steps and a recheck:
- Picture descriptions (alt text). Images without an
altattribute are reported, and a purposely emptyalt=""on a decorative image is not treated as a mistake. - Broken images. Image addresses that answer with an error are listed with the pages that use them.
- Heavy and unoptimized images. From the speed test: oversized files, images in older formats, and images that slow the largest visible element of the page.
- The largest visible image. Whether the main image of a page loads in good time, with the speed test's own measurement.
How Image Doctor works
-
1. Scan the images
After you prove the website is yours and a full scan has run, Crawvix builds a list of the images written into your pages' HTML (up to 2,000): where each is used, its description, and how the page loads it. For up to 200 of them it also asks the server for the file size, type and whether the address works. One image used on ten pages is listed once, with ten places of use, because the right description can depend on where the picture appears.
-
2. See what needs attention, with evidence
Problems are sorted by how much they matter. Each shows the image address, the pages that use it, exactly what we measured and the next step. Where we are not sure, for example a description that might be too generic, it is marked review, never as a definite failure.
-
3. Get suggestions you control
On request, Crawvix proposes a description for each image from the page around it, or recommends an empty description when the picture is only decoration. You see the original and the proposal side by side, edit it, and approve only what you want. Nothing is invented: we do not make up materials, sizes, brands or claims the page does not show.
-
4. Take the fixes with you
Download a spreadsheet with every image, the pages that use it, its current description and what to fix, and a second one with the descriptions you approved. Press Optimize my images to get one ZIP of lighter WebP copies of your heaviest JPEG and PNG pictures, with a list that shows which file replaces which address and how much smaller each one is. Your original files are never touched, and Crawvix never changes your website by itself: you upload the new files.
-
5. Recheck
After you publish your changes, run a new full scan. The list is rebuilt from your live pages, so an image you fixed no longer shows the problem, with the time of the scan on the screen. A side-by-side "fixed since last time" view is planned.
What is ready and what is coming
We would rather tell you plainly than promise early. This table is updated when something ships.
| Stage | What it does | Status |
|---|---|---|
| Image checks in the scan | Alt text, broken images, heavy images and the main image, with evidence, fix steps and rechecks. | Available now, in every plan |
| Image list and screen | Every unique image, where it is used, its size and status, and its problems, with filters and a spreadsheet export. Built after each full scan of a verified website. | Available now, in every plan |
| Fix my images | Converts your heaviest JPEG and PNG pictures to WebP in our own code and gives you one ZIP with the new files, a README that shows the savings and where each file goes, and a fix list of every image problem with what to do. Verified websites only; the number per press and per month depends on your plan. | Available now, in every plan |
| Suggested descriptions (Alt Text Writer) | One suggestion per image that you edit, approve or reject, and a spreadsheet of the approved ones. Some suggestions are included in every plan. | Built; switched on for customers once its first live test is done. A larger monthly allowance as an optional add-on is planned |
| Changes through your own tools | For example a proposed change to your repository for you to review. Only with your explicit permission, a preview and your approval each time. | Later; not started |
What we promise, and what we do not
- Crawvix reads your website; it does not change it. Anything that would change your website will be a separate, clearly labelled option you turn on, with a preview and your approval each time.
- Full image checks run only on websites you have proved you own.
- Better descriptions and lighter images make pages easier to use and faster to load. We do not promise higher search rankings, and fixing images alone does not make a website accessibility-compliant.
- The numbers in any example on this page are illustrations. The numbers in your account come from your own scans.
- The Images screen lists the images written into your pages' HTML. Pictures drawn by a style sheet (a CSS background) or by a script are not listed yet, and we do not ask for or store the pictures themselves, only their address, size and type.
