Frequently asked questions

Is this background remover really free?

Yes. The Webnow Remove Background tool is 100% free, has no watermarks, requires no signup, and has no daily limits.

Do my files get uploaded to a server?

No. All processing runs locally inside your browser using HTML5 Canvas and the PDF.js library. Your image, PDF, or text file never leaves your device.

Which file formats can I upload?

You can upload any common image (PNG, JPG, JPEG, WebP, GIF, BMP, SVG-rasterized), single-page or multi-page PDF documents (the first page is rendered), and plain text (.txt) files.

Which output formats are supported?

You can download the result as a transparent PNG, transparent WebP, JPEG, or BMP. JPEG and BMP do not support transparency, so you can pick a background fill (mat) color before exporting.

How is the background detected?

The tool samples the border pixels of your image and picks the dominant color, which is almost always the background. You can also click the eyedropper and pick any color directly from the image, or open the color picker to set it manually.

What do tolerance and edge softness do?

Tolerance controls how similar a pixel must be to the background color to be removed (higher = more aggressive). Edge softness feathers the alpha mask so cutouts blend cleanly without jagged edges.

Can it auto-crop the empty space around the subject?

Yes. Enable Auto-crop to automatically trim fully transparent borders so the exported image is tightly cropped around the remaining subject.

Does it work on mobile?

Yes. The tool is fully responsive and runs in any modern mobile browser (Chrome, Safari, Firefox, Edge).
