How to Save a Krita Image with a Transparent Background

The short answer

To save a Krita image with a transparent background, make sure no opaque layer fills the canvas, then export the image to a format that supports an alpha channel, such as PNG, and leave the option to store the alpha channel (transparency) enabled. JPEG cannot store transparency, so exporting to JPEG fills the empty areas with a solid color. Krita's own .kra format also keeps transparency, but most other programs cannot open it.

There is one important condition. If the document was created with a solid background color, or if it contains a filled background layer, that layer must be hidden, deleted, or made transparent first. Otherwise the export will be opaque no matter which format you choose.

Why transparency sometimes disappears on export

Transparency is stored in the alpha channel, which is extra per-pixel information describing how opaque each pixel is. Krita displays fully transparent areas as a gray-and-white checkerboard. If you see white or another solid color instead of that checkerboard, something opaque is still covering the canvas. Two causes are most common. The first is a background layer, often named "Background", created automatically with the document. The second is a canvas background color set in the new-document settings. Exporting to a format without alpha support is a third cause, because that removes transparency even when the canvas itself is transparent.

Steps to export a transparent image

The menu names below reflect Krita's usual layout. Labels and option names can change between versions, so check them against the version you have installed.

• 1. Open the Layers docker and find any layer that fills the whole canvas with a solid color, typically the bottom layer named Background.
• 2. Hide that layer by clicking its visibility (eye) icon, or delete it if you no longer need it.
• 3. Confirm that the empty areas of the canvas now show the checkerboard pattern.
• 4. If the checkerboard still does not appear, check the document's canvas background setting. A background color set when the document was created can still show behind the layers. Setting it to a fully transparent color, or recreating the document with a transparent background, resolves this.
• 5. Choose File > Export, which is separate from Save As, and select PNG as the file type. WebP and TIFF also support transparency if you need a different format.
• 6. In the PNG options dialog, keep the option to store the alpha channel (transparency) checked, then confirm the export.

Starting a new document with a transparent background

If you know in advance that you need transparency, set it when you create the file. In the File > New dialog, the content or background section lets you pick a background color and its opacity. Setting the opacity to zero, or choosing a transparent option where one is offered, starts the canvas without an opaque fill. This avoids the hidden-background problem described above.

How to confirm the result

Reopen the exported PNG in Krita. Transparent areas should show the checkerboard rather than a solid color. Placing the file over a colored layer or a different background in another program is also a reliable test: the underlying color should show through the empty areas. Some simple image viewers render transparency as black or white, so a solid color in a basic viewer does not by itself prove the export failed.

Using the image with virtual cameras and video backgrounds

A transparent PNG is a common choice for overlays such as logos, frames, or name cards in streaming and virtual-camera software, because only the drawn parts cover the video. Whether a particular application respects the alpha channel depends on that application. Check its documentation or preview the overlay before you go live. Background replacement features in conferencing apps usually expect a full, opaque image rather than a transparent one. A transparent file used as a replacement background may show black or default fill where the alpha is empty.

What this guide does not cover

This topic concerns image files only. Saving a transparent image in Krita has no effect on webcam microphone selection, speech capture, or audio quality, so no audio setup steps apply here. No version-specific evidence was supplied for this article, so treat the exact menu paths and option labels above as general guidance and confirm them in your installed version of Krita.
