How to make a carousel readable on mobile

A slide that looks clear on a large monitor can be difficult to read in a mobile feed. Review the smallest text and the meaning of each visual element. Readability and accessibility need your review after generation and again after export.

Quick answer

Check every exported slide at a normal phone viewing size. Shorten crowded text, use clear contrast and keep essential content away from cropped edges. Provide the key information as plain text too: Carousel AI exports slide images, and its PDF export currently does not add selectable text or accessibility tags.

Reduce the amount of text before shrinking the font

Give each slide one job and make the heading state it clearly. Replace a long paragraph with a shorter explanation or a few distinct points. In the preview, enter edit mode to adjust text and use the font controls when necessary. If the idea still feels crowded, revise the wording rather than forcing every sentence into the design.

Example brief

Before: “In order to improve the organization of your study routine, it is important to establish priorities beforehand.” After: “Choose one study goal.” The shorter version leaves room for a concrete example below it.

Check contrast, spacing and the photo behind the text

Read the smallest text against its actual background. A busy stock photo can make a heading disappear even when the text color seems suitable elsewhere. Replace the image or adjust the layout and colors. Keep labels close to the item they explain, leave space around paragraphs and keep important content inside the area that remains after the publishing crop.

Make the meaning clear without color alone

When comparing options, write labels such as Recommended and Check first instead of relying only on green and red. Explain icons, arrows and abbreviations in words when they carry information. A decorative photo does not need to communicate a second message that the text never explains. If a diagram is essential, include its conclusion in the written explanation.

Keep a text equivalent of the useful information

PNG slides contain text as pixels. Carousel AI’s current PDF export also embeds captured images and does not create a tagged document with a text layer. Put the essential steps in a readable caption, article or other text format; add image descriptions through the destination’s controls where available. The W3C images tutorial recommends text alternatives that convey the information in an image. A visually clear export alone does not establish accessibility.

Review the actual files on a phone

Export the PNG ZIP or PDF, open it on your phone and inspect every slide without relying on zoom. Check the title, body text, order, final action and any watermark. Then review the upload preview on the destination for cropping or compression changes. Keep this check in your publishing routine; a larger desktop preview cannot show every reading problem a mobile viewer may encounter.

Frequently asked questions

Does a larger exported image guarantee readable text?

No. Resolution preserves detail, but reading also depends on the font, the amount of text, contrast and the size at which the image is displayed. Check the exported slide at a normal phone viewing size.

Is the exported PDF automatically accessible?

The current PDF exporter embeds images of the slides and does not add selectable text or accessibility tags. Provide a readable text equivalent and review the requirements of the destination where you share it.

Does the app publish an image description for each slide?

The current direct publishing workflow sends slide media and a post caption; it does not expose a per-slide alternative-text editor. Use the destination’s available controls and provide the important information in text.
