Lower means more see-through. 50% is a balanced ghost effect.
How it works
Add your images
Drop in photos or logos you want to turn into soft see-through layers.
Choose opacity
Slide opacity down for a faint ghost or up for a barely-there tint over backgrounds.
Download ghost PNGs
Preview the translucency, then save PNGs with real alpha you can layer anywhere.
Turn any picture into a gentle overlay
Overlays, watermarks, letterheads and slide backgrounds all need images that sit quietly behind text instead of shouting over it. This tool multiplies every pixel alpha channel by your chosen opacity, so the whole picture becomes evenly see-through while colours, shading and existing transparency stay proportional. A fifty percent setting turns a busy photograph into a calm wash that remains recognisable yet lets foreground headings, buttons and captions stay crisp and readable on top of it in any layout.
Unlike simply lowering brightness or washing a picture white, true alpha translucency lets whatever sits underneath show through in a physically honest way. Place the exported PNG over paper textures, brand colours or other photos in any editor and the blend looks like frosted glass rather than a faded print. Because the math scales existing alpha too, logos that already had soft rims keep those rims, only becoming proportionally lighter across the entire frame without harsh new borders or banding artefacts.
Pick the right opacity for the job
Opacity near twenty percent creates a whisper of an image suited to full-page document watermarks, presentation backdrops and website hero washes where legibility matters most. Values near fifty percent suit collage layers, before-and-after reveals and ghost portraits where both layers should be visible at once. Settings above seventy-five percent add only a delicate veil, useful for toning down overly punchy stock photos before placing white text over them without resorting to coloured boxes or heavy drop shadows.
Always export as PNG because JPG has no alpha channel and bakes translucency against white, destroying the see-through effect entirely. Keep your source files safe, since each run writes fresh copies and never alters originals. If the preview looks too faint on a bright monitor, nudge opacity up by ten points and test the PNG over its real destination background, because checkerboard previews in browsers tend to make mid opacities look lighter than they appear over dark designs and photographs.
Ghost layers rendered privately beside you
No server ever sees your pictures, because the translucency math executes locally inside your browser tab on your own hardware. Cloud overlay makers often log filenames, keep thumbnails or inject tracking pixels into downloads, yet here the alpha multiplication runs in sandboxed page memory and vanishes the moment you close the tab, leaving no trace on any distant machine, analytics pipeline or advertising profile tied to your creative work.
There is no account, no queue and no expiry: open Semitransparent image when a deck needs a backdrop, process up to ten files, download the ghost PNGs and move on. Your browser stores only the app code for offline reuse, never your artwork. Re-run with a different opacity any time from the untouched originals until the overlay sits perfectly behind your words and shapes in every context.
Questions
Are my photos sent anywhere for processing?
No. Opacity is applied by your own browser. Files never leave your device.
Is it free?
Yes. Free to use with no sign-up, no watermark and no daily limits.
Why must I use PNG and not JPG?
JPG has no transparency, so translucency is lost and baked against white. PNG keeps the alpha channel, so overlays stay see-through.
Will it keep existing transparency?
Yes. Existing alpha is scaled proportionally, so soft edges and holes stay correct, only lighter overall.
