JPG, PNG or WebP - paint what stays visible, then download a PNG8 for X

Private by design - the checkerboard transform and PNG8 export run entirely in your browser. Your image is never uploaded to our servers.

How it works

X flattens transparent PNGs onto a white thumbnail in the timeline, and shows the original on black when you tap and hold. A 1×1 checkerboard of solid and transparent pixels exploits that difference.

1

Upload a JPG, PNG, or WebP of the image you want to hide.

2

Paint the areas that should stay visible in the timeline thumbnail.

3

Compare the white-timeline vs black tap-hold previews live.

4

Download the PNG8 file and post it on x.com from a desktop browser.

Frequently asked questions

A tap hold (tap-to-reveal, kakushie) image is a transparent PNG that looks faint in the X / Twitter timeline and shows its real colors when someone taps and holds to enlarge it. This tool builds that effect with a 1×1 checkerboard of solid and pure-white transparent pixels (same grid used by taphold.org), then exports PNG8 for reliable X processing.
X handles indexed-color PNGs (PNG8) with transparency differently from ordinary RGBA PNGs. PNG8 with a tRNS transparency chunk is the encoding used by reliable kakushie generators, so the hide effect works on both light and dark timelines.
No. The mobile apps often convert images to JPEG and strip transparency, which breaks the trick. Upload the PNG8 file from a desktop browser on x.com, wait a minute or two for processing, then check the timeline on mobile.
No. All processing runs in your browser with the HTML canvas. Your picture never leaves your device - nothing is stored or sent to AppGrowthKit servers.
After you upload, use the brush to paint areas that should remain solid in the timeline thumbnail (a teaser outline or caption). Everything you leave unpainted is hidden behind the checkerboard until someone taps and holds. Raise brightness boost (+0% to +50%) if the long-press reveal looks dim on X's black viewer.
The before/after previews composite the PNG onto white (timeline) and black (tap-hold) backgrounds in your browser. Real X thumbnails also resize and re-encode the image, so the live post can look slightly different - but the same checkerboard + PNG8 mechanics drive both.

Attention on X, conversion on the store

Tap-hold and kakushie posts earn curiosity. Installs still happen on App Store and Google Play pages - and those pages live or die on screenshot quality.

When a campaign drives traffic to your listing, AppGrowthKit gets the screenshots ready: polished frames, clear captions, and store-ready export so the click becomes an install.
