Question: Is there a service that allows me to upload images and download them with transparent backgrounds?

If you need a service to upload photos and download transparent background versions, Removal.AI is a good option. The AI-powered tool uses machine learning algorithms to identify foreground and background pixels and split them. You can upload batches of photos and get transparent, white or custom backgrounds in three seconds. It's geared for e-commerce, graphic design and product photography, and has a tiered pricing system with a free plan and relatively cheap monthly and lifetime plans.

Another option is Clipping Magic. It's got an AI-powered editor that will automatically remove backgrounds, but you can also use manual tools and a range of options like smart edges, graphics mode and adaptive brush size for more control. It can handle a variety of file formats, and you can pay monthly or annually.

If you're looking for something more basic but still relatively cheap, Remove.bg is a good option. It's an automated tool that uses AI to remove backgrounds, and it can handle JPG and PNG images up to 22 megabytes. It offers a free plan, and you can buy credits in bulk for a discount. The service is GDPR compliant, which means it's got a system to protect your privacy.

If you want something completely free, Erase.bg offers a basic way to remove backgrounds from photos and get transparent images. It's good for e-commerce or personal projects, and you can download the edited images without paying a penny. It's good for anyone who wants a quick and easy way to improve their visual assets.
