Imagera lets you change background color in a photo using an automatic subject selection and a new fill. This free background color changer is for sellers, designers and people updating portraits. Add a JPG, PNG, WebP or HEIC picture, choose a solid color or gradient, and compare the outline. Processing runs locally in a supported browser on a phone, tablet or computer. 2 free downloads, 8 more after sign-in.
Published · Updated · by the Imagera teamImagera is a browser-based AI studio for images, video, music and voice, so you do not need a separate app and account for every model. Pricing is credit-based: one balance covers every tool, and each job shows its credit price or estimate before you run it.
















Recorded results from this tool. Results vary with the source image, settings and device. Drag each handle to compare.






Subject detection starts with a 320 × 320 working image, or 102,400 pixels. A separate edge pass uses the photo’s colors to refine that selection.
The gradient derives 2 endpoint colors from your chosen shade: a lighter tint and a darker shade. It creates a colored backdrop, not a photographed location.
Try Luxury Background ChangerA 2000 × 1500 source contains 3 million pixels. Changing its backdrop keeps those dimensions when they fit the browser’s canvas limits; it does not add resolution.
Choose from White, Black, Custom color or Gradient in Background; the starting choice is White. To convert a complex background to a single color, choose a solid fill and run the automatic subject selection. You do not need to trace its outline before running the change.
For a custom shade, use the swatches or open the Color picker. This is useful for a portrait, a product card or a set of images that need the same backdrop. Keep the color choice consistent, then review each subject’s outline separately.
The gradient uses your chosen color to make lighter and darker areas behind the subject. It does not offer separate endpoint or direction controls. Choose a solid fill when you need a uniform field of color.
Enable Soft shadow if the subject needs a little separation from its new surroundings. This adds a blurred, offset shadow based on the detected silhouette. It does not preserve the original floor shadow or recreate the lighting of a real studio.
Changing a pale background to a dark one can expose a leftover fringe. The engine refines the selection and reduces old backdrop color around its edges, then blends the subject into the new fill. Fine hair, fur and narrow gaps can still need attention.
Edge cleanup can alter partly selected pixels, so this is not a promise to preserve every subject color exactly. Check glass, reflective surfaces and translucent fabric carefully. The tool has no manual selection brush for repairing those regions.
The result is a flattened, opaque photo. The subject and its new background are saved together, with no separate layer to recolor later. Its file type may differ from the image you added, and the export uses lossy compression. Keep the original for future changes.
Large inputs can be reduced to fit the device’s canvas limits. A large saved picture also does not guarantee that each fine edge was detected at full size. Compare the result at the size you intend to display it.
Your picture is read and processed on your device. The browser downloads the subject model and attempts to cache it for later use. A first run can therefore include loading time as well as the color change itself.
A dedicated graphics card is not required, but the browser must support the processing features. If an older phone cannot finish the background replacement, use a reduced picture or run the color change in a current desktop browser. Changing the fill on your device still involves website network requests as well as the subject-model download.
Use this page when the job is a new backdrop color. The separate White Background Maker handles the white-only workflow, and Background Remover makes a transparent cutout for a layered design.
For a room, outdoor setting or other generated scene, use the linked Luxury Background Changer. To recolor clothing or the product itself, use Edit Image. This color tool has no prompt field or replacement-photo input, and it does not relight the subject.
Choose a JPG, PNG, WebP or HEIC picture with a distinct person, product or pet in the foreground.
Set Background to one of White, Black, Custom color or Gradient. For a custom fill or gradient, pick the shade under Color; add Soft shadow if needed.
Start processing, then use the comparison slider to inspect hair, product outlines and any shadow against the original.

Add your photo, choose the new backdrop treatment and start processing. The tool detects the foreground automatically. Compare the edges before using the finished picture.
Yes. The background choices are White, Black, Custom color or Gradient. Use the custom fill and its color picker for shades beyond the fixed choices.
The tool opens your browser’s native color picker. Some browsers offer a hex entry there; this page does not provide a separate hex text field. When available, use that entry for the chosen shade. Compression and edge blending mean the exported pixels are not guaranteed to match the code everywhere.
Yes. Choose the gradient background and set its base shade with Color. The lighter and darker endpoints are calculated for you; they cannot be set independently.
The tool does not separately extract and preserve the original cast shadow. Soft shadow adds a new soft shadow from the subject selection. Inspect its placement before using the image for a product listing.
The fill targets the detected background, not clothing or product color. However, selection errors, edge cleanup and export compression can affect subject pixels. Check color-sensitive details against your original.
Fine edges can contain a mixture of subject and old background color. Automatic cleanup reduces that mixture but may not remove it completely. Try a less contrasting fill or refine the selection in a separate editor if the fringe remains distracting.
You can try, but transparent surfaces need special care. The subject selection and edge correction cannot guarantee accurate glass, liquid or reflections. Inspect those areas closely; a layered editor may be needed for manual correction.
No. This tool saves the new fill as an opaque part of the photo. Use Background Remover instead if another layer needs to show through behind the subject.
The photo is re-encoded with lossy compression. Dimensions stay at the decoded size unless the device’s canvas limits require a smaller image. Neither unchanged dimensions nor a clean fill guarantees perfect fine detail.
Use a supported mobile browser and choose a photo from your device. The color controls work in the browser, with no separate editing app needed. Older browsers or limited memory can prevent a run from finishing.
No photo upload is part of this engine’s processing path. Your browser performs subject detection and compositing locally. Network requests load the page, runtime and model.
The browser needs a subject detector before it can separate the foreground. Cached model files can be reused while browser storage remains available. Loading and processing times vary with your connection and device.
Processing stops when the model detects too little foreground to keep. Try a photo where a person or object stands apart from the surroundings. This tool is not a manual paint bucket for recoloring an empty wall or landscape.
There is no replacement-image input here. The available backdrops are fills created by the tool. For a generated location, follow the Luxury Background Changer link; for your own backdrop photo, use a layered editor.
The input formats are JPG, PNG, WebP or HEIC. The output is a flattened photo in the engine’s fixed export format, so it may not retain the source file type.
