JPEG layer opacity tool.

Layer editing relies on alpha, and JPEG cannot store it. Converted to a PNG with opacity, the photo becomes a proper layer that composites correctly with everything under it.

Keep it at 100 and let the editor's opacity slider do the blending, which stays adjustable. Bake a lower opacity in only when the transparency must be fixed, for a web asset for instance.

Process the JPEG here, download the PNG, place it in Photoshop as a new layer. The transparency comes with it. Useful when Photoshop is out of reach or several photos need the same fixed transparency.

A 50 percent layer is an instant half-and-half blend. For multiply, screen and the other blend modes, import at 100 and use the editor's modes, which need the full image data.

CSS can set opacity and blend modes itself, but a pre-baked PNG saves the browser the work and gives a fixed look across pages. Export the variant you need.

A linear fade makes an edge flow into the layer below; a radial fade makes a focal mask. Both replace manual masking in the editor.

Uniform sets one opacity for the whole photo, from a faint ghost at 10 percent to nearly solid at 90. Linear fades from one edge to the other in the direction you choose; radial keeps the middle solid and fades toward the edges, or the other way round, with a radius you set.

Draw an area selection around the subject. A radial fade then centers on that area rather than on the frame, so an off-center face stays solid while the rest falls away.

No. The file is decoded, drawn and re-encoded by your browser's canvas, and the page makes no request with it. You can load the page, go offline and keep working; nothing is stored either.

No. The JPEG layer opacity tool is free and opens without a sign-in, an account or an install.

Nothing. The JPEG layer opacity tool holds your input in the page's memory, so closing or reloading the tab clears it, and it saves nothing in this browser.

Up to 100 MB per file, the limit the tool states under its drop area. A larger file is refused with a plain message instead of being decoded.

No, it takes one file at a time. If you drop or choose several, only the first is used; run the tool again for the next one.

The edit is written as a PNG because PNG stores every pixel exactly, with a full alpha channel, so the result can be edited again without a second round of loss.

No. The browser decodes the image and the tool writes a new file from its pixels, so camera EXIF, GPS position and text chunks in the original are not copied into the result. Keep the original file if you need them.

No. The result has the same width and height in pixels as the source.
