# Add a solid background on this device

> Add a white or custom colour behind photos and transparent PNGs in your browser. Always free. 100% private, because files never leave this device.

Put white, black, or any colour behind a logo, product shot, or screenshot. Clear pixels get filled. Nothing is uploaded.

Online Image Converter. Language: English. https://onlineimageconverter.net/add-background

## How to start

1. Drop one image or a batch. Files stay on this device.
2. Choose white, black, or a custom colour.
3. Pick JPG, PNG, or WebP, and set quality if you are not saving PNG.
4. Apply the background, then download each file or a zip of the batch.

## Notes

- Start with white for product photos and most logos.
- JPG always fills transparency. If you still need a clear background, keep the PNG and skip this tool.
- A custom colour is the value you pick. It does not sample the photo.
- Quality around 0.92 is a good balance for JPG and WebP. Lower values make smaller files and softer edges.

## Price

Always free. There is no account, no paid tier, and no watermark.

## What this site does not do

- There is no upload API, no account, and no paid tier. Photos are not sent to or stored by the site.
- Output formats are JPG, PNG, WebP, and still GIF. SVG can be opened as an input and saved as PNG with transparency.
- HEIC and HEIF can be opened in current Chrome, Firefox, Safari, and Edge. A local decoder runs in the tab when the browser cannot decode HEIC itself. AVIF stills can be opened in current browsers.
- There is no convert-to-HEIC. Animated AVIF is not supported. GIF output is a still picture. An animated GIF becomes one frame.
- This site does not make PDFs. For converting images into a PDF, use JPG to PDF on [❤️ LoveThisPDF](https://lovethispdf.com/tools/jpg-to-pdf), which also runs in the browser.
- It does not add Content Credentials (C2PA). It can strip them on Remove EXIF & GPS.
- Converting JPG to PNG keeps the picture opaque. Remove background can clear one flat colour.

## Requirements

Any phone, tablet, or computer with a browser. Nothing to install. HEIC and AVIF convert in current Chrome, Firefox, Safari, and Edge. A decoder runs in this tab when the browser cannot open HEIC itself. Very old browsers may still need a JPG from the iPhone. Very large images may fail if the device runs out of memory. Results can differ between browsers because encoders (especially WebP and JPEG quality) are implemented by the browser vendor.
