A tap and hold caption has one practical job: tell people which action reveals the second state. It should be short enough to scan, specific enough to avoid confusion, and honest about spoilers or sensitive content. The image carries the surprise, while the caption provides the instruction and context.
Upload a source image, paint the hidden region, compare both states, then export a PNG that preserves alpha.
Upload, mask, preview, and export without sending the source image to an image-processing server.
Use “Tap and hold to reveal,” “Long press for the second version,” or “Press the image to see what changed.” These captions work when the post itself already explains the subject.
Avoid a long technical explanation of alpha channels or PNG rendering. Viewers need an action and a reason, not the production method.
Try “Long press for the alternate expression,” “Hold to reveal the final panel,” or “The punchline is hidden in the image.” Match the wording to the actual payoff.
Do not promise a transformation that the image does not deliver. A precise caption builds trust and makes replies more likely to focus on the artwork or joke.
State the topic before asking for interaction. For example, “Episode finale spoiler, long press only if you have watched it.” Give people a real choice.
Do not hide safety information, critical context, or misleading claims behind the interaction. Reveal formats work best as entertainment and creative presentation.
Use “Long press to see the redesign,” “Hold to reveal the new feature,” or “Before first, result on reveal.” Add one link or next step after the instruction.
Keep the product name and value clear in normal text. The reveal can create attention, but it should not make the launch inaccessible to people whose device renders the image differently.
No. The MVP editor processes jpg, png, and webp files in the browser with Canvas. The image is not sent to a server by default, which keeps creator drafts private.
PNG keeps the alpha channel. The transparent area is what lets a reveal image behave differently between a compressed timeline preview and a long-press or expanded view.
Social platforms resize, compress, and preview images differently. RevealStudio gives a browser preview and conservative export defaults, but the final result can vary after platform processing.
No account is required. The source image stays on your device while you prepare the transparent PNG.
