Free Indoor Map Maker: How to Create Interactive Floor Plans Online
You do not need CAD software or a mapping SDK to create an interactive indoor map. If you have a floor plan image โ even a photo of one โ you can turn it into a searchable, interactive map in minutes. Here is how. For a full comparison of indoor navigation technologies in 2026, see our technology guide.
What counts as a floor plan
Anything that shows the layout of your space. Architect's drawings, fire escape plans (usually posted near elevators), hand-drawn sketches, screenshots from Google Maps satellite view, or even a photo taken from a high vantage point.
The image does not need to be to scale or architecturally precise. It needs to be recognizable to visitors โ when they see it on their phone, they should think "yes, that is this building."
Getting a floor plan if you don't have one
Ask your building manager or facilities team โ they almost certainly have floor plans, even if they are old paper copies. A phone photo of a paper floor plan works fine.
For outdoor spaces like campuses or resort grounds, take a screenshot from Google Maps or OpenStreetMap. Crop it to show just your property.
As a last resort, draw one. Use any drawing tool โ even PowerPoint or Google Slides. Draw rectangles for rooms, label them, and export as an image. Simple maps are often clearer than detailed architectural drawings.
Creating your interactive map
Upload your floor plan image to QRCodeMaps (free trial available). The platform accepts JPEG, PNG, and WebP files up to 5 MB. Your image appears as an interactive, pannable, zoomable map.
Click anywhere on the image to place a marker. Give it a name that visitors will search for. Add a description if the name alone is not enough. Choose a color to visually categorize markers if you want.
Repeat for every location worth marking. For a hotel floor, that might be 15-30 markers. For a warehouse, it could be 50+.
Making it interactive for visitors
Toggle QR codes on for any markers you want to make scannable. Each gets a unique QR code that, when scanned, opens the map centered on that location with a "You are here" badge. For printing and placement advice, see our QR code placement best practices.
Visitors can then search for any other marked location. Results work across all maps in your site โ so a visitor on Floor 1 can search for a room on Floor 3 and see it on the correct map.
The entire experience runs in the phone's web browser. No app download, no account creation, no Wi-Fi required (it works on mobile data).
Tips for better maps
Use high-contrast images โ dark lines on white background scan better on phone screens than faded or low-contrast plans. Crop out unnecessary whitespace around the floor plan.
Name markers the way a visitor would search: "Restroom" not "WC", "Parking Level 2" not "P2". Include alternate names in the description field if a location goes by multiple names.
Test on a phone screen. What looks clear on your desktop monitor might be hard to read on a 6-inch phone display. If the text on your floor plan image is too small to read on a phone, consider using a simplified version.
