How to make an infographic in a minute
- Pick a template. A bar comparison for numbers, or a flow diagram for how things connect. Each starts filled in with an example, so you can see what goes where.
- Write the headline. Say the finding, not the topic: "Ranking in Google's top 10 won't get you cited by most AI engines" beats "AI citation study". Put *asterisks* around the words that matter and they turn indigo.
- Add your data or cards. Paste rows from Excel or Google Sheets, or edit the inputs, hub and output of the flow diagram.
- Choose a size and download. 16:9, square or portrait. Download the PNG, or copy it and paste it straight into a post, doc or slide.
Bar chart infographic: compare values at a glance
The bar comparison shows one value across up to 16 items, such as conversion rate by channel, share of answers by AI engine or survey results by group. Each row has a label, a value and an optional detail, such as the count behind a percentage, which helps readers trust a small sample.
The Rows field takes data in any of these shapes, one row per line:
Google AI Overviews 36% 36 of 99 URLs
Claude, 14%, 7 of 50 URLs
Revenue; 1.250,50 €
*Email 4.2%Columns copied from a spreadsheet are separated by tabs, which is what you get when you paste. Commas and semicolons work too, and numbers with thousands separators stay whole. A line that starts with * is highlighted in indigo, or click the row's name under "Highlight in indigo". When some rows are highlighted and others aren't, the chart adds a legend and a dashed line between the groups.
By default the largest value fills its bar and the rest are drawn in proportion. For percentages, choose "Out of 100" so a 36% bar fills about a third of the track.
Flow diagram: show how things connect
The flow diagram puts a column of inputs on the left, a hub in the middle and an output on the right: the data sources behind a report, the tools that feed a CRM, the steps that lead to a decision. Each input card has an icon, a title, a "how" line and a "what" line, plus an optional badge such as "New" or "Premium". The dashed connectors are drawn from where the cards actually sit, so they always meet the hub, however many inputs you add.
The output can be chat messages, for the questions people ask an assistant, or a checklist, for the reports, alerts or decisions that come out of the process.
Infographic sizes for LinkedIn, X, Instagram and slides
| Size | Canvas | PNG | Works well for |
|---|---|---|---|
| 16:9 | 1600 × 900 | 3200 × 1800 | Slides, blog posts, X and newsletters |
| Square | 1080 × 1080 | 2160 × 2160 | LinkedIn and Instagram feeds |
| Portrait | 1080 × 1350 | 2160 × 2700 | LinkedIn and Instagram feeds, where a 4:5 image takes up the most room on a phone |
On square and portrait canvases, each bar sits under its label so the chart still reads on a phone, and the flow diagram's output moves under the hub.
Tips for an infographic people actually read
- One message per image. If the headline needs "and", it's probably two infographics.
- Highlight the rows that prove the point. Indigo for the group the headline is about, the lighter shade for everything it's compared with.
- Order bars on purpose. Largest first for a ranking; your own order when the sequence means something, such as funnel steps or months.
- Say where the numbers come from. A source line with the sample, the date and the method answers the first question in the comments.
- Keep labels short. Everything resizes to fit, but a two-word label stays readable at phone size.
Frequently asked questions
Is the infographic maker free?
Yes. There's no signup and no limit on how many images you make. The images are yours to use anywhere, including client work, reports and ads.
Is the data I type kept private?
Yes. The infographic is drawn and turned into a PNG in your browser, so nothing you type or upload is sent to OneLence. Your work is saved in your own browser so it's still there next time, and "Start over" clears it.
How do I make a bar chart from Excel or Google Sheets?
Select two or three columns in your sheet (label, value and an optional detail such as "36 of 99"), copy them and paste them into the Rows field. The chart updates as you paste. A first row of column headings is left out on its own, and values such as 36%, 1,250, $4.2k or 36,5 all work.
Does the infographic carry a watermark?
Only a small, grey "Made with OneLence" line in the bottom corner, and you can switch it off. It credits the tool, not your numbers: OneLence doesn't check or vouch for the data you enter.
What resolution is the PNG?
Twice the canvas size: 3200 × 1800 for 16:9, 2160 × 2160 for square and 2160 × 2700 for portrait. That keeps text sharp on high-resolution screens and after LinkedIn or X compress the image.
What happens if my title or labels are long?
Text resizes to fit. The title gets smaller to stay within a few lines, then the chart or diagram scales down until everything fits the canvas, so nothing is cut off. Short titles and labels still read best on a phone.
Which kinds of infographic can I make?
Two for now: a bar comparison, for comparing a value across up to 16 items, and a flow diagram, for showing how up to 8 inputs feed one tool, team or process and what comes out of it.
Can I use my own logo?
In the flow diagram, yes: choose "Your logo" for the hub and pick an image file. It stays in your browser.
