About the Add Background to Transparent PNG

A transparent PNG looks great on the page you designed it for and disappears everywhere else — dark mode, a Word document, a print shop's black background. This tool flattens transparency by painting a background first and drawing your image over it, so the logo or cut-out you have always sits on something solid.

Choose a solid colour with a picker and six quick swatches, a two-stop linear gradient at any angle from 0 to 360 degrees, or a checkerboard with an adjustable square size. Export as an opaque PNG when you want lossless output, or as JPG with a quality slider when file size matters more — JPG has no alpha channel, so flattening first is mandatory.

The original and the flattened version sit side by side so you can check the edges, with transparency drawn as a checkerboard on the left. Everything happens on a canvas in your browser: processing is 100% local, nothing is uploaded to a server, and the download is rendered at full resolution.

Frequently asked questions

How do I add a white background to a transparent PNG?

Drop the PNG in, leave the background style on solid colour and click the white quick swatch. The preview flattens immediately, and Download PNG saves an opaque file that will look identical everywhere, including in Word, PowerPoint and dark-mode email clients.

Why does my logo disappear on dark backgrounds?

Transparent PNGs show whatever is behind them, so black artwork on a transparent background vanishes on a dark page. Flattening it onto a chosen background colour guarantees the same appearance no matter where the file is used.

Can I convert a transparent PNG to JPG?

Yes, and adding a background is the correct way to do it. JPEG has no alpha channel, so unflattened transparency usually turns black. Pick your background here, choose JPG as the output format and set the quality slider before downloading.

Does adding a background reduce image quality?

Not when you export as PNG, which is lossless and keeps every pixel of the original. Exporting as JPG applies lossy compression, so keep the quality slider around 85 to 95 for photographs and prefer PNG for logos, text and flat graphics.

Is my image uploaded anywhere?

No. The background is painted and your image composited over it on a canvas in your own browser. No file is sent to a server, which keeps unreleased logos and client artwork private.
