How to Make a Graphical Abstract Without Illustrator or Photoshop

TL;DR

You do not need Adobe Illustrator or Photoshop to make a graphical abstract that meets a journal's requirements. There are three realistic routes: presentation tools you already own (PowerPoint, Google Slides), a free vector editor (Inkscape), or an AI graphical abstract generator built for the job. Each trades off time, control, and how easily you hit each journal's export settings. Here is how to choose.

Why researchers look for an Illustrator alternative

Illustrator is powerful, but it carries a monthly subscription and a real learning curve — a lot to take on for the one figure most papers need. Photoshop has the same problem and is built for photos, not diagrams. If you make a graphical abstract once or twice a year, a lighter tool almost always makes more sense.

Option 1: PowerPoint or Google Slides

You already know these, and they are free (or already paid for). Set the slide size to your target journal's dimensions, build the figure with shapes, icons, and text boxes, then export as an image.

The catch is resolution. Slides default to about 96 DPI on screen — well below the 300 DPI floor almost every publisher requires. You have to raise the export resolution manually, or the figure will pixelate in print. We walk through the exact steps in our guide to making a graphical abstract in PowerPoint.

Option 2: Inkscape (free vector editor)

Inkscape is a free, open-source vector editor — the closest like-for-like Illustrator alternative. It produces clean vector artwork and exports to PNG and other raster formats at any resolution.

The trade-offs: the learning curve is similar to Illustrator, and there is no built-in scientific icon library, so you draw or source elements yourself. Good if you want full manual control and zero software cost.

Option 3: AI graphical abstract generators

The fastest route if you don't have design skills. You paste your abstract text (optionally letting AI turn it into a visual brief) or upload a rough hand sketch, the tool generates the figure, and you pick your target journal to export at the correct size and DPI. Abfig is built specifically for this workflow.

Two honest caveats: always review AI-generated figures for scientific accuracy before submitting — labels, arrows, and relationships should match your findings exactly — and check your target journal's policy on AI-generated images, since several major publishers require disclosure and some do not accept AI-generated figures at all.

Which route should you choose?

Route	Best for	Watch out for
PowerPoint / Slides	Simple layouts, tools you know	Must raise DPI on export
Inkscape	Full vector control, zero cost	Learning curve, no icon library
AI generator	No design skills, want it journal-sized fast	Review for accuracy + check journal AI policy

Whatever tool you pick, check these before submitting

• Dimensions match your target journal — see the journal specifications hub.
• Resolution is at least 300 DPI — verify with our DPI checker.
• Fonts stay legible after the image is scaled into a small display window.
• File format is one your journal accepts (many take TIFF or PNG).

Conclusion

Illustrator is optional. PowerPoint works if you don't mind fixing the resolution, Inkscape suits people who want vector control for free, and an AI generator is fastest when you have a paper to submit and no time to learn design software. Whichever you choose, build to your journal's exact size from the start.
