What Is an X Reveal Image?
An X reveal image looks like a normal picture while scrolling, then shows more once you press and hold it — a technique built specifically around how X renders images.

Since the platform's rebrand from Twitter to X, the same tap-and-hold picture format has increasingly been described as an 'X reveal image' — the newer name for what's still the same underlying mechanic. Whether someone calls it a reveal image, a hidden image, or a tap and hold image, they're describing one technique: a picture that shows less in the timeline and more once you interact with it.
This page defines exactly what an X reveal image is, why it depends specifically on how X — not any generic platform — handles image rendering, and walks through building one with the free CarouseLabs Tap & Hold Image Maker.
What “What Is X Reveal Image” Means
An X reveal image is a single image file that displays differently depending on how X is rendering it at that moment. While scrolling the timeline, X applies a fast compression pass to keep the feed loading quickly, and that pass reduces detail unevenly across the image — some regions hold up, others flatten out. When a viewer taps and holds the image on mobile, X switches briefly to a higher-fidelity render meant for closer inspection, and the regions that flattened out in the timeline pass become visible again.
Building an X reveal image means intentionally deciding which regions should hold up under the timeline's compression and which should depend on the tap-and-hold render instead. That's done with a brush tool — paint what should survive the timeline view, leave the rest unpainted so it depends on the reveal — which is exactly how the CarouseLabs Tap & Hold Image Maker is designed to work, with both rendering states shown live as you paint.
Why People Use This Effect
X reveal images do well specifically on X because the platform's fast, high-volume scrolling behavior makes a static, fully-visible image easy to ignore. A reveal image resists that instant judgment by design, which is exactly the kind of friction that makes people pause on a feed built for speed.
The format also benefits from being closely tied to X's specific interaction model — the tap-and-hold gesture is native to how people already browse X on mobile, so using it doesn't require teaching people a new gesture, only a new expectation about what that familiar gesture can reveal.
How to Create This with CarouseLabs
Here's exactly how to build an X reveal image using the free CarouseLabs Tap & Hold Image Maker.
- 1
Open the CarouseLabs Tap & Hold Image Maker
Go to /tools/tap-hold-maker. It's free, browser-based, and doesn't require creating an account.
30 sec - 2
Upload your source image
Add a JPG, PNG, or WebP by dragging it in or using the file picker. The image is processed locally in your browser, not sent to a server while you edit.
15 sec - 3
Paint the portion that should show in the X timeline
Use the brush to mark what stays visible under X's timeline compression. Everything left unpainted becomes the reveal, shown only when a viewer taps and holds. Undo and Clear are available if needed.
1-2 min - 4
Check the timeline view and reveal view side by side
Timeline View approximates what shows while scrolling on X; Tap & Hold View shows the full reveal on a black background, exactly as it appears during a tap-and-hold press.
30 sec - 5
Download the X-optimized file
Use 'Download for X' to export a PNG-8 tuned for X's specific compression behavior, or export WebP if you plan to use the image outside of X.
10 sec - 6
Post it on X from a desktop browser
Upload through X on desktop rather than the mobile app, since the app applies additional compression that can undermine the reveal. Mobile viewers can then tap and hold to see it.

Try it as you read
Open the maker in another tab and follow along with the steps above.
Tips for Better Results
Remember the effect is X-specific
The reveal depends on how X specifically renders images during a tap-and-hold press, so this technique is built and optimized for posting on X.
Use the PNG-8 export for anything posted on X
The 'Download for X' option in the CarouseLabs Tap & Hold Image Maker is tuned specifically for X's compression behavior — it's the safer default over WebP for X posts.
Design around the tap-and-hold gesture, not a click
The reveal is triggered by a mobile press-and-hold, so preview your image with that interaction in mind rather than a desktop hover or click.
Check Tap & Hold View as your final confirmation
It's the closest simulation of what X's tap-and-hold render will actually show, so treat it as the deciding preview before you download.
Keep the visible portion legible at small sizes
Timeline thumbnails on X can appear fairly small, so make sure the visible part of your reveal image still reads clearly at that scale.
Examples
Product-teaser reveal image
A partial product shot stays visible in the X timeline; the full product reveal appears on tap and hold.
Portrait-to-scene reveal image
A close-up portrait stays visible while the wider scene around it is hidden until tap and hold.
Icon-to-photo reveal image
A simple graphic or icon stays visible in the timeline while a full photo is the hidden reveal.
Common Mistakes
Expecting the reveal to work the same way on other platforms
Fix: The effect depends on X's specific rendering behavior for tap and hold. Exporting the WebP version is better suited for sharing on platforms other than X.
Posting from the X mobile app
Fix: The app's own image compression on upload can interfere with the reveal. Always post the downloaded file from a desktop browser.
Choosing a source image that's too low resolution
Fix: A low-resolution source limits how distinct the timeline and reveal states can look. Start with a reasonably high-resolution image.
Not testing the reveal before relying on it for an important post
Fix: Always confirm Tap & Hold View shows the intended reveal in the CarouseLabs Tap & Hold Image Maker before posting anything time-sensitive.
Frequently Asked Questions
An X reveal image is the tap-and-hold technique described in X's current terms — a picture built so part of it depends on X's higher-fidelity press-and-hold render rather than its compressed timeline render.
