PhotoAid's AI Image Enlarger vs BgSub

PhotoAid's AI Image Enlarger upscales photos in the browser without a software download. You upload a JPEG, WEBP, or PNG file up to 30MB or 10,000 by 10,000 pixels, pick a 1x or 2x zoom level, and the tool doubles dimensions while smoothing detail instead of leaving blocky pixels.

Standard resize tools stretch pixels and blur faces fast. PhotoAid's upscaler uses AI smoothing tuned especially for portraits, so a 1000 by 1000 px image can become 2000 by 2000 px with fewer artifacts than a basic bicubic stretch.

The enlarger is free and hosted by PhotoAiD, the same team behind passport and visa photo tools on photoaid.com. They released it as a standalone browser utility alongside their biometric photo pipeline, with multilingual site options and links back to other PhotoAid tools.

PhotoAid's AI Image Enlarger fits photographers, ecommerce sellers, and anyone who needs a quick upscale for profile shots or product images. It also helps travelers who already use PhotoAid for passport photos and want a separate enlargement step in the same ecosystem.

BgSub removes or replaces photo backgrounds inside your browser without uploading files to a server. The marketing site promises results in about 5 seconds, with one-click cutouts, replacement fills using color, gradients, or images, and an AI coloring pass for quick color tweaks. Processing stays local enough that BgSub highlights a no-upload privacy story on the homepage.

Most background removers send every image to the cloud by default. BgSub leans on in-browser processing and calls out that images are not uploaded during editing, which matters when you are working with client product shots or personal portraits. It also bundles artistic effects plus free adjustment controls for size, position, and mirroring instead of stopping at a plain transparent PNG.

The tool targets individuals polishing social photos, e-commerce sellers refreshing product shots, photographers swapping backgrounds without a green screen, and marketers testing ad creatives. Sample galleries on bgsub.com show people, products, animals, clothes, and plants, and the FAQ notes commercial use is allowed on processed images.
