Turn any photo into a clickable guide with the free image hotspot maker — add markers, tooltips, and export JSON or PNG.
An image hotspot maker turns a flat picture into a clickable guide: you drop numbered markers onto the image, attach a short title and description to each one, and visitors tap a marker to see exactly what that part is, what it costs, or where to go next. Instead of reading a long caption or hunting through separate pages, they explore the image itself.
That small change matters because most product, property, and training images are asked to do too much on their own. A single photo of a furnished room, a machine, or a campus map has to explain ten things at once — and a paragraph underneath it rarely gets read. Hotspots put the explanation exactly where the eye already is.
What is an image hotspot maker?
An image hotspot maker is a free online tool that lets you add interactive, numbered hotspots with titles and descriptions to any image, preview the tooltips as a visitor would see them, and export the result as JSON or as an annotated PNG. You upload one image, click to place each marker, write what it should say, and share or embed the finished result — no coding and no design software required.
The image hotspot maker from CodexFuse follows exactly that flow: upload, click to place, preview, export. It is free and unlimited, so a small team can annotate a whole catalogue without buying a licence or waiting for a developer.
Why a beautiful image still fails to sell, teach, or explain
Look at a typical product page. There is a large photo, five thumbnails, a bullet list of features, and a specification table somewhere below the fold. The visitor's attention splits in three directions, and the connection between "that handle in the photo" and "stainless steel, soft-close, included in the price" never quite forms.
The same problem shows up far from retail. A training manager sends a labelled diagram of a warehouse layout, and new starters still ask where the fire exits and charging bays are. An estate agent photographs a flat, and every viewing request asks the same three questions the photo was supposed to answer. A museum puts a painting online, and the story behind each detail stays locked in a separate essay nobody opens.
In each case the image is not the problem. The missing piece is a way to attach information to the exact pixel it describes, at the moment the viewer is curious about it.
How to make interactive hotspots in three steps
Using the CodexFuse tool takes minutes, not a project plan. The live tool page describes the same three steps, so what follows matches what you will actually see on screen.
- Upload your image. Choose the photo or diagram you want to annotate — a product shot, a floor plan, a team photo, or an infographic. Start with the sharpest version you have, because hotspots placed on a blurry image will look vague on larger screens.
- Click to place each hotspot. Click on the exact feature you want to explain, then add its title and description. Keep each description to one or two useful sentences: what it is, why it matters, and what to do next. Repeat for every feature worth a marker.
- Preview, then export. Preview the tooltips to check the wording reads well and no marker hides another one. Export as JSON if you need the hotspot data for a website or app, or as an annotated PNG if you need a shareable, static version with the markers visible.
Write hotspot text for someone who has never seen the product. "Solid oak frame, seats three, removable covers" beats "Premium quality sofa" every time, because it answers the question the visitor was about to ask.
A worked example: one living-room photo, five buying decisions
Consider a fictional furniture retailer, Northwood Living, selling a three-seater sofa through a single hero photograph of a styled living room. Before hotspots, the page carried one long description and a separate specification table. Visitors kept emailing to ask which rug, lamp, and side table were in the photo, and whether the sofa covers could be removed.
Northwood's marketing lead uploads the 2400 × 1600 JPEG to the image hotspot maker and places five markers in around 12 minutes:
| Hotspot | Title | What the tooltip says |
|---|---|---|
| 1 — Sofa | Harlow 3-Seater Sofa — £1,150 | Solid oak frame, removable washable covers, seats three. Add to basket from this page. |
| 2 — Floor lamp | Arden Floor Lamp — £145 | Brushed brass, dimmable, bulb included. Pairs with the Harlow range. |
| 3 — Rug | Kiln Wool Rug 200 × 290 cm — £320 | Hand-knotted wool, non-slip backing included, vacuum-friendly. |
| 4 — Side table | Otto Side Table — £95 | Solid walnut top, assembly in under five minutes, no tools needed. |
| 5 — Wall art | Print only — not for sale | Styling prop. Similar prints are listed under Wall Decor. |
The result is immediate. A shopper who likes the lamp no longer has to guess its name, search the catalogue, and hope they found the right one. They tap the marker, see the price and the key detail, and move on. Northwood also exports the JSON version for its website, so the same five markers work on mobile, where most of its traffic already arrives. No new photoshoot, no page redesign, no developer sprint — just the same image, made answerable.
The lesson generalises. Any image that currently generates repeat questions — a machine diagram, a campus map, a menu board, a before-and-after renovation shot — is a candidate for the same treatment. If people keep asking "what is that part?", that part needs a hotspot.
Where interactive hotspots actually pay off
- Product and catalogue pages: link each visible item to its name, price, and product page, so a styled photo becomes a shoppable scene instead of a guessing game.
- Property and floor plans: mark room dimensions, heating type, storage, and renovation dates directly on the plan, cutting the round of "is that room en-suite?" messages.
- Training and safety diagrams: label controls, hazards, exits, and shut-off points on one diagram, so new starters learn locations by tapping rather than memorising a manual.
- Tourism and campus maps: turn a static map into a self-guided tour, with each building, trailhead, or exhibit carrying its opening hours and a short story.
- Infographics and reports: let readers drill into a chart or diagram without leaving the page, keeping the overview clean and the detail one tap away.
If visitors keep emailing about details your images already show, CodexFuse can help you turn those images into a managed, shoppable site: hosting, business email, security, and backups handled for you, on pay-as-you-go credits with no subscription.
Get Started with CodexFuseWhat makes a hotspot helpful instead of annoying?
More markers is not better. A photo with 20 pulsing dots feels like a minefield, and visitors stop tapping after the third irrelevant tooltip. The strongest annotated images follow a few restrained rules.
- Five to seven markers maximum: cover the features people actually ask about, and leave the rest to the normal description. If everything is highlighted, nothing stands out.
- One fact plus one action per tooltip: a useful tooltip says what the thing is and what to do next — view it, buy it, book it — in two sentences at most.
- Space markers apart: on a phone screen, markers placed too close together are impossible to tap accurately. If two features overlap, combine them into one hotspot or choose a wider crop.
- Never hide the image: markers should invite a tap, not cover the product. Small numbered dots with a tooltip on tap work better than large panels that obscure the photo before anyone interacts.
- Test on a phone first: most visitors will meet your annotated image on mobile. Preview there, check tap targets, and shorten any tooltip that needs scrolling.
Hotspots help visitors who can see and tap the image, but they do not replace accessible text. Keep the essential facts — price, dimensions, safety information — in the page text as well, so screen-reader users and search engines can reach them too.
What an image hotspot maker cannot do
Honesty matters here, because the tool is deliberately simple. An image hotspot maker does not track clicks or build analytics dashboards, so if you need to know which marker gets tapped most, pair the export with your site's own analytics. It does not animate the image, build a 360-degree viewer, or replace a full product configurator — a sofa in five colours still needs a configurator, not five dots.
It also does not fix a weak photograph. A dark, cluttered, or low-resolution image with hotspots is still a dark, cluttered, low-resolution image. If the photo itself needs work, start with basic editing first — for example, cleaning up a background or adjusting framing — before annotating it. For related image work, see the image colour picker and the before-and-after comparison slider guides.
From one annotated image to a managed site that sells
One annotated image is a quick win. A catalogue full of them needs a site that stays fast, secure, and online while you keep adding products — and that is where a managed platform earns its keep. CodexFuse is an all-in-one, fully managed IT platform that runs on credits: you pay as you go, with no subscription and no lock-in, and the team handles hosting, security, and backups for you.
A practical workflow for a small retailer looks like this. First, annotate your hero images with the free image hotspot maker and export the JSON for your site. Next, host the site on CodexFuse's managed hosting, so you are not babysitting servers, patching software, or worrying about an update breaking the page at midnight. Add business email on your own domain for order and enquiry mail, and let automated backups protect the catalogue you just spent weeks photographing. Because the platform runs on credits, a quiet month costs less and a busy season simply uses more credits — there is no plan to upgrade or downgrade, and no surprise renewal bill.
That combination — a free tool for the image, a managed platform for everything around it — is the point. The hotspot solves the visitor's confusion. The platform removes the owner's maintenance burden. Neither requires hiring a developer or signing a long contract.
If you work with images every day, these guides pair well with this one: how to annotate and mark up images, how to write image descriptions automatically, and how to compress images without losing quality.
Frequently Asked Questions
Is the image hotspot maker really free?
Yes. The CodexFuse tool page states it is free and unlimited: you can upload images, add hotspots with titles and descriptions, preview tooltips, and export JSON or an annotated PNG without paying or creating a paid plan.
What can I export from the image hotspot maker?
You can export the hotspot data as JSON, which suits websites and apps that render interactive markers, or as an annotated PNG, which suits sharing, presentations, and documents where the markers need to stay visible in a static file.
Do I need coding skills to add hotspots?
No. The workflow is upload, click to place, write a title and description, preview, and export. If you need the JSON version on a custom website, a developer can help with that one integration step, but creating the hotspots themselves needs no code.
How many hotspots should I add to one image?
Typically five to seven. Cover the features visitors ask about most, keep each tooltip to one fact plus one action, and space markers so they are easy to tap on a phone. More than that usually reduces taps rather than increasing them.
Will hotspots work on mobile phones?
Yes, provided markers are spaced well and tooltips are short. Always preview on a phone before publishing, because tap targets that feel fine on a desktop monitor can be frustratingly small on a mobile screen.
Can hotspots replace my product descriptions?
No, and they should not. Hotspots answer questions at the exact point of curiosity, but full descriptions, specifications, and prices should still live in the page text for accessibility, search engines, and visitors who prefer to read rather than tap.
