How to Remove Backgrounds from a Batch of Images
Prepare a manageable queue, review every cutout, and download files with a clear naming and export plan.
Plan a batch before adding every file
Pick one representative photo and test the complete workflow first. Check the cutout, choose the final background and canvas, and open an exported file. Then group similar images together. A set of product photos for one square catalog is easier to review than portraits, wide banners and glass packaging with different export needs.
Process and review the queue
- Open Background Remover. Pro users can select Enter license key to activate their plan. Free users can continue without an account or key.
- Choose Options before starting if you need a Pro File name pattern or the High-quality model. High quality is available only when the device passes the tool’s WebGPU capability check; it is not supported on every device.
- Use click to choose to select multiple images, or drop them together. The standard model downloads about 44 MB on first use; high quality downloads about 115 MB. After loading, images are processed one at a time on your device.
- Select each finished image in the list and inspect Result and Compare. Check missed objects and damaged edges. Successful processing means a file was produced; it does not mean the cutout passed your visual review.
- Choose Background and Export size for the batch. Pro users can select Download all (ZIP). Free users download images separately with Download PNG or Download JPG.
Understand names, PNG files and shared settings
The Pro filename pattern accepts {name} for the original filename without its extension, {index} for a three-digit position, and {date} for the export date. For example, {name}-cutout-{index} makes outputs easier to identify. Keep the source folder so you can trace a questionable edge back to its original image.
The ZIP contains PNG files for successfully completed images only. It uses the background and export-size settings currently selected. White makes the PNGs opaque; Transparent retains transparency. These settings are shared across the batch, so split images into separate batches when they need different canvas sizes or backgrounds.
Handle failures without losing track
If processing stops, read the message and use Try again when offered. Stop interrupts processing; completed results remain available. A corrupt file needs a fresh export from its source app, while memory problems often need fewer images or smaller dimensions. Large files and ZIP creation can use substantial memory even though inference runs sequentially.
Open the ZIP and compare the output count with the completed count. Inspect difficult images before publishing. Glimbench has no manual erase or restore brush, and AI can miss hair, glass or low-contrast boundaries. A smaller reviewed batch is more useful than a large unchecked folder.
