Drop a picture and drag Opacity to fade it: at 100% it is untouched, at 50% it is half see-through, at 0% it disappears completely. The checkerboard behind the preview is the transparency showing through, so what you see is what the file will look like laid over something else. This is the quick way to make an image transparent for a slide, a document background, a faint watermark, a website header or a layer you want to put on top of another photo. Press Download and you get a PNG with the fade built into it: drop it into PowerPoint, Google Slides, Word, Canva or any editor and it stays semi-transparent without touching that program's own transparency settings.
A logo, a signature or a cut-out with a transparent background keeps its empty areas. The slider scales the transparency every pixel already has instead of replacing it, so the background stays fully clear and only the visible part gets lighter: a logo at 30% is a soft watermark, not a grey rectangle. A photo with no transparency at all fades evenly across the whole frame. The colours themselves never change - the image is not washed out toward white, it becomes see-through, which is why it looks right on a dark background as well as a light one. To remove a white background first, use the remove white background tool; to fade only the edges, feather edges.
Opacity lives in the alpha channel, so the download offers PNG and WebP, the two common formats that keep it. PNG is lossless and opens everywhere; WebP is much smaller for photos and works in every current browser and most editors. JPG is left out on purpose: it has no transparency, and a faded JPG would come out darkened on black instead of see-through. The file keeps the full resolution of the original. You can rename it before saving, copy it straight to the clipboard to paste into a chat or document, or share it from a phone.
A picture you want to make transparent is often a company logo, a signature or a photo for a presentation that is not public yet. None of it leaves your device: the image is decoded, faded and encoded by your own browser, with no upload, no account and no watermark.
Open it here, drag Opacity down until it is as see-through as you want and download the PNG. 100% leaves the image as it was, 50% makes it half transparent and 0% makes it fully invisible. The checkerboard in the preview shows how much of what is behind it will show through.
Yes. Every pixel's own transparency is multiplied by the slider value, so areas that were already clear stay clear and only the visible parts fade. A logo on a transparent background comes out as a lighter logo on the same transparent background.
JPG has no alpha channel, so it cannot store see-through pixels at all. Any transparency would be flattened onto a solid colour when saved. PNG and WebP both store it, which is why those are the two formats offered.
Only when it is placed over something light. The colours are not changed; the picture becomes see-through, so over white it looks paler and over black it looks darker. That is what makes it work as an overlay on any background.
No. The fade is calculated in your browser on your own device, so a logo, a signature or an unpublished slide never leaves it.
