Add a White Background to Transparent PNGs
Flatten transparent PNGs onto a white background — required by marketplaces like Amazon and many print shops.
About the Add White Background
Amazon, Etsy and most print services reject transparent images — they need white backgrounds. This tool flattens your PNG's alpha onto pure white and outputs a clean JPG or PNG, batch-ready for marketplace uploads.
How it works
The tool composites each transparent image over an opaque white canvas: every alpha pixel blends against white, and the output loses its alpha channel entirely. JPEG output makes files smaller; PNG output stays lossless if the destination is picky about formats.
How to use it
Drop up to 10 transparent PNGs (or WebPs), choose JPEG or PNG output, and process. Each result previews on solid white so you can confirm nothing unexpected was hiding in the transparency.
Supported formats & limitations
Accepts .png and .webp inputs up to 30MB each, 10 per batch. Semi-transparent edges (soft shadows, anti-aliasing) blend toward white permanently — preview before downloading if edges carry subtle alpha.
Common use cases
Meeting marketplace image requirements that ban transparency, preparing print-shop files, sending designs to clients whose software shows checkerboards, and converting overlays into presentation-safe images.
Frequently asked questions
How private is Add White Background?
Everything runs locally in your browser via the Canvas API. Your picture never leaves your machine — there is no upload step at all, so processing is as private as working in an offline editor.
What kind of image files work with this tool?
PNG or WEBP inputs are supported, up to 30 MB per file. For exotic formats, convert them first with one of the converter tools, then come back.
What are the size and batch limits?
You can queue 10 files per run, each up to 30 MB. Results download individually or bundled as a single ZIP.
Can I fine-tune the result before downloading?
You can adjust Output format. Results are previewed after processing, so tweak values and re-run until the output looks right.
