SVG opacity changer.

Some places can't apply it: email clients, some CMS fields, legacy software, anything that wants a plain image. A PNG with the alpha baked in works everywhere, and the transparency can't be overridden.

The SVG is drawn fresh at its declared size, so it is as sharp as the vector at that size. For a larger output, set a larger width and height in the SVG editor first.

Yes. The opacity applies evenly to every element; the colors keep their relationship, just fainter overall.

The new alpha multiplies the old: an element at 50 percent given 50 percent ends at 25. Fully transparent areas stay transparent.

A radial fade gives a glow, solid in the middle and clear at the edges; a linear fade makes a directional transition for decorative elements.

One file at a time. Note the settings and apply them to each; the numeric controls make the result reproducible.

The browser draws the SVG to pixels at the size it declares (its width and height, or its viewBox), and the tool works on those pixels. The result is a PNG, not an SVG: for a larger output, set a larger width and height on the SVG first, with the SVG editor.

No. The file is read and drawn by your browser, and the page makes no request with it. You can load the page, go offline and keep working; nothing is stored either, so reload and it is gone.

No. The SVG opacity changer is free and opens without a sign-in, an account or an install.

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

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.
