Most Business Photos Have Useless Alt Text
Alt text is the short line a screen reader speaks and a search engine reads for an image.
Screen readers hear nothing useful
"IMG 2041" tells a blind visitor nothing about your work.
Keyword piles look spammy
"AC repair Henderson best AC repair Henderson NV" reads badly to people and to Google.
Writing it takes time
Fifty job photos means fifty sentences, and most people give up after five.
A pattern fixes it
Subject, detail and place, in one plain sentence. This tool writes that pattern for you.
On most small business sites it is empty, a file name, or a pile of keywords.
What "Free" Means on This Alt Text Generator
The tool is free with no signup and no daily limit.
You get
- 3 to 5 alt text options per photo
- A title and a caption to match
- Four quality checks on every line
- Bulk mode for up to 500 file names

It is honest about one thing up front: it does not look at your photo.
AI tools describe what is in the pixels. This tool writes from what you tell it, so the facts are yours and nothing is guessed.
Always check each line against the real photo.
How the Alt Text Generator Works Under the Hood
It is a template engine that runs in your browser.
Your details
Business name, business type, main service and the city where the photo was taken.
Photo type
Pick one of eight: technician, equipment, before and after, team, vehicle, storefront, finished job or product.
The detail
A short note on what is really in the photo. This one field does the most for quality.
Templates
Five or six patterns per photo type are filled, cleaned and trimmed to 125 characters.
Checks
Each option is scored for length, opener, keyword repeats and stuffing. Passing lines show first.
More options
Press again to rotate the patterns and get different wording.
Your details fill sentence patterns written for each kind of business photo.
The Four Checks on Every Line
Each option shows its character count, word count and four checks.
Under 125 characters
Short lines are easier to listen to and stay on the main subject.
No "image of" opener
Screen readers already announce an image, so start with the subject.
Keyword used once
Your service and city should appear at most once each.
No keyword stuffing
Flags words used three times, repeated phrases and lines with three or more commas.
Change the text and the checks update as you type.
Bad Alt Text vs Good Alt Text
Here is what the difference looks like in practice.
image of ac repair henderson nv best ac repair
- Better
- Technician replacing a capacitor on a Trane AC unit in Henderson, NV
before after plumbing plumber plumbing services
- Better
- Before and after of a corroded water heater swapped for a tankless unit
team photo
- Better
- The Desert Air team standing beside their service vans
picture of our store
- Better
- Front entrance of a bakery on Main Street with the sign lit up
The good versions say what the photo shows, once, in plain words.
How Bulk Mode Reads Your File Names
Paste one file name per line, up to 500.
Splits the name
Dashes, underscores and spaces become words. Numbers and words like final, edit or copy are dropped.
Finds the place
A two letter US state code at the end marks the city before it. Elsewhere, the city comes from the form.
Flags camera names
Names like IMG_2041 or DSC0042 use your form values and get a rename note.
Exports a CSV
File name, alt text, character count, checks, title, caption and notes for every row.
The tool pulls the service and location from each name and writes a full row for it.
Template Alt Text vs AI Alt Text Generators
AI generators and this template tool solve different problems.

Alt Text Mistakes the Tool Helps You Avoid
These are the patterns that make alt text worse for people and search engines.
Starting with "image of" or "picture of".
Start with the subject. The checker flags this opener.
Repeating the keyword and city.
Use each once. The tool counts both for you.
The same line on ten photos.
Add the detail that makes each photo different. Bulk mode also varies the wording.
Keyword alt text on decorative images.
Use an empty alt attribute for patterns, dividers and textures.
What Missing Alt Text Costs You
Missing alt text shuts out visitors who use screen readers and gives search engines less to go on.
Lost visitors
People using screen readers cannot tell what your work looks like.
Weaker image search
Google Images relies on alt text and nearby text to understand a photo.
Accessibility risk
Missing alt text is one of the most common accessibility errors on small sites.
Google's image SEO guidance and the WCAG accessibility rules both ask for useful alt text.

Alt Text Generator FAQ
10 answers about limits, results and how the tool works.
Is this alt text generator free?
Yes. It is free, there is no signup and there is no daily limit. Everything runs in your browser from written templates, so nothing you type is sent to a server. Use it for one photo, or paste up to 500 file names in bulk mode and download a CSV.
Does this tool use AI to look at my photo?
No. It does not see your image at all. It fills sentence patterns with your business name, service, city and the detail you type. That keeps it fast and private, but you must check each line against the real photo. If it says technician and the photo shows a van, change it.
How long should alt text be?
Aim for one plain sentence, usually under 125 characters. Many screen readers can read longer text, but short alt text is easier to listen to and keeps the focus on the main subject. The tool counts characters and words for each option and flags anything over 125.
Should I put my city in alt text?
Only when it is true and helpful. A photo from a real job in Henderson can say so once. Do not paste the city into every image on the site, and never add towns you did not work in. The page around the image already gives Google location context.
What is the difference between alt text, title and caption?
Alt text is read by screen readers and used by search engines to understand the image. The title attribute shows as a small tooltip on hover in some browsers. A caption is visible text under the photo that everyone reads. This tool writes all three for each photo.
Can I use the same alt text on several photos?
Try not to. Ten photos with the same line tell a screen reader user nothing new, and it looks lazy to search engines. Add what makes each photo different, like the brand, the room or the step of the job. Bulk mode varies the wording, but details must come from you.
Do decorative images need alt text?
No. Background patterns, dividers and stock textures should use an empty alt attribute, written as alt with two quote marks and nothing between. That tells screen readers to skip them. Save real alt text for job photos, team shots, storefronts and products that carry meaning.
How does bulk mode read my file names?
It splits each name on dashes, underscores and spaces, drops numbers and words like final or edit, and looks for a two letter US state code at the end. The words before it become the city. Camera names like IMG_2041 use the form values and get a rename note.
Where do I paste the alt text on my website?
Every major platform has an alt text field. In WordPress it is in the media library sidebar. In Shopify, open the image and choose edit alt text. Wix and Squarespace show it in the image settings panel. Paste the line there, not into the file name or caption.
Is AI alt text better than this tool?
It depends on your photos. AI tools are useful for big libraries where nobody knows the details. For your own job photos, you already know the brand, the place and the work done, and AI can guess those wrong. This tool turns your facts into clean, checked sentences.
