Add a Solid Background to a Transparent PNG
By Yasir Yaseen · Updated November 2026
Fill the see-through parts of a cutout with white or any other colour. It is a plain canvas fill done in your browser, with no AI step and no model download.

What happens to your file
For each image, the tool creates a canvas at the image's own pixel size, fills it with the chosen colour, draws your image on top and exports a PNG. Nothing is resized or recompressed beyond PNG encoding, so a 3000 × 2000 cutout stays 3000 × 2000.
Files are accepted at up to 20 MB each, and you can select up to 50 at once. One image gives a before and after preview; two or more run as a batch, one after another, with a ZIP download at the end. A non-image file or a file over the size limit rejects the whole selection.
Choosing among the presets
- White (#ffffff)
- Pure white, RGB 255, 255, 255. Amazon has long required a pure white background for main product images; marketplace requirements change, so check the marketplace's current rules before you publish.
- Light gray (#f5f5f5)
- Softer than white and shows white or pale products better. Not suitable where a marketplace requires pure white.
- Black (#000000)
- High drama for jewellery, electronics and dark-mode graphics. Dark subjects vanish into it, and light fringes from a rough cutout become obvious.
- Navy (#1e3a5f)
- A usable brand-style backdrop for headshots and speaker cards. Check contrast with dark hair or clothing.
- Sky blue, mint, blush, yellow
- Pale tints for social posts, thumbnails and flat-lay style cards. They are presets only; for a brand colour, enter its hex value in the custom picker.
Decide by destination
| Where the image goes | What to do |
|---|---|
| Marketplace listing with a stated background rule | Follow the rule exactly. If it says pure white, use the white preset, not light gray. |
| Website product grid where the page is white | White blends the image edge into the page; light gray gives a visible card. |
| Print or ID-style photo with a colour requirement | Check the issuing authority's current specification for the shade and for any pixel size or file limits. |
| Logo for a dark and a light page | Keep the transparent PNG and use a fill only for the places that need a solid background. |
From transparent PNG to upload-ready JPG
A JPG cannot hold transparency, and a converter that meets a transparent PNG has to pick some colour for those pixels, often black. Running Add background first means you choose that colour deliberately. A typical sequence is Background Remover, then Add background with white, then Resize to the size the destination asks for, then Convert format to JPG. The Continue with bar under each result hands the file to the next step without a new upload.
The pixel dimensions and file-size caps differ by marketplace and change over time, so confirm them in the marketplace's own seller documentation rather than relying on a figure from a third-party page.
Questions about this tool
- I uploaded a JPG and nothing visible changed. Why?
- The tool paints a solid colour over the whole canvas and then draws your image on top. A JPG has no transparent pixels, so it covers the colour completely and the result looks identical to the input. The fill only shows through transparent or semi-transparent areas, such as a PNG made with the Background Remover.
- Why is the file I download a PNG, not a JPG?
- The output is always a PNG with the original pixel dimensions and the same file name, now with a .png extension. It is fully opaque when the picked colour is opaque. If a site demands JPG, use Convert format from the Continue with bar. That flattening step is safe at this point because there is no transparency left to lose.
- Can I apply a different colour to each image in a batch?
- No. One colour is chosen per run and applied to every file, up to 50 images of 20 MB each, processed one at a time. For two colours, run two batches, for example one set for white catalogue shots and one for a coloured social template.
- There is a faint light or dark outline around my subject. Can I fix it here?
- Not in this tool. Soft cutout edges contain semi-transparent pixels that were mixed with the original background colour. Those pixels blend with your new colour, so a light fringe stands out on a dark fill and a dark fringe on a light fill. Pick a fill close to the original background, or redo the cutout from a sharper source.
- Can I upload a photo as the background?
- This page only does solid colours: eight presets plus any custom colour from the browser colour picker. To place a subject on a photo, use Replace background, which takes two images.
