Upload from desktop x.com so transparency survives. Mobile apps often re-encode to JPEG. Light-mode timelines show the effect best.

How masking works

  • Default: whole image hidden in feed, full color when opened.
  • Blue paint: regions visible in the feed before tap.
  • PNG8 export is tuned for X; post from desktop web.

Frequently Asked Questions

Creators post a single PNG that looks washed out or partially hidden in the X timeline, then shows the full artwork when someone opens the post or uses tap-and-hold on mobile. The effect comes from how X composites transparency in the feed versus the full-screen viewer. It is not a special X setting.

Upload your art to a tap-to-reveal encoder, paint where the feed should stay visible if you want partial previews, tune line art or open brightness, then export PNG8. Post the file as a normal image on X from desktop web (x.com) for the most reliable upload path.

X blends alternating transparent pixels in timeline previews. This encoder writes those regions so the feed shows a muted version while the opened view uses the full-color pixels.

PNG8 is tuned for posting on X (indexed color, smaller file). RGBA is useful if you want a lossless master or to edit elsewhere; re-export PNG8 before posting if X rejects large RGBA files.

No. Encoding, masking, and export run in this tab. Image bytes are not uploaded to Toolioz. The website still loads scripts and analytics. You upload to X yourself if you post.

No. Split-tile posts use multiple images in one tweet. Tap-to-reveal uses one PNG with a transparency pattern for feed versus opened. This tool builds that single file.

Mobile apps often re-encode uploads to JPEG, which destroys the transparency pattern the trend relies on. Uploading PNG from desktop x.com keeps the hidden feed effect intact.

Square and 4:5 presets match common timeline crops. Keep important detail away from extreme edges, preview both light and dark timeline backgrounds in the tool, and export PNG8 before posting.

Yes. Teasers, before and after reveals, and puzzle-style art hide detail in the timeline until viewers tap. Use the brush mask to show a logo or headline in-feed while hiding the rest until open.

Tap-to-reveal images follow X image rules, not a hack

This tool composites a cover frame and a hidden frame into a PNG that X (Twitter) can show as a spoiler-style image depending on current client behaviour. Platform rules change. If a post is rejected, the cause is the network media policy, not a Toolioz "ban."

What to expect

Keep both layers within the size and aspect ratio the composer shows. Illegal, sexual, or violent content is still against X rules whether or not it is "hidden." Do not use the tool to evade safety filters. Preview on a throwaway draft before a wide post.

Processing is local when labelled. The PNG you download is just a file; we do not post it to X for you.

Worked examples

  • Aspect ratio

    A 16:9 pair that is then letterboxed by the composer may look different in the X crop. Match the canvas the UI recommends.

Limits of this page

  • Client apps on iOS, Android, and web can render spoilers differently after an X update.
