Bria Guided Remove Background — AI Image Background Remover (Image-to-Image)

What is Bria Guided Remove Background?

Bria Guided Remove Background is a prompt-controlled background remover that lets you say, in plain English, exactly what a cutout should keep or drop. It starts from Bria's state-of-the-art RMBG-2.0 segmentation and then follows your words: add an item the standard cut misses, drop one it keeps, or narrow the cut to a single named object. A missing or blank prompt returns a standard one-click background removal, so the same endpoint handles both automatic cutouts and guided edits.

The output is a true-alpha PNG at the input's original resolution. No pixels are repainted — only a new alpha channel is added — so your subject keeps its exact colors and detail, ready to composite over any background.

Key Features

• •Prompt-guided cutouts: add, remove, or narrow the foreground with natural language ("only the chair", "the player without the dog").
• •True-alpha output: transparent PNG at original resolution, original pixels untouched.
• •Clean soft edges: RMBG-2.0 sub-pixel mattes keep hair and fur crisp against transparency.
• •preserve_alpha: retains partial transparency from inputs that already carry an alpha channel.
• •Built-in moderation: optional input and output content checks for safe, scalable pipelines.
• •Commercially safe: trained exclusively on licensed data.

Best Use Cases

Guided removal shines when a one-click remover is too blunt. For e-commerce, keep a product plus its prop while dropping a stray hand or a second item. For marketing and design, isolate one object from a styled flat-lay, or pull a single subject out of a cluttered interior, table setting, or workspace where there is no obvious foreground. Because cutouts return at full resolution with a clean matte, they drop straight into Photoshop, Figma, or a graphics stack without a halo, and pair naturally with downstream replace-background or lifestyle-shot steps. Scripting the prompt makes cutouts predictable and repeatable across large image sets.

Prompt Tips and Output Quality

Name your target by a distinctive attribute — color plus object type ("the red accordion") reads more reliably than a bare noun. Use "only the …" to narrow to one subject, "… without the …" to drop one element, and "… with the …" to keep extras the default cut discards. Leave the prompt blank for a plain removal. Keep preserve_alpha on so fine hair and fur edges stay soft. Highest-resolution originals give the cleanest mattes; very low-resolution inputs and fine glass reflections are the hardest cases.

How to Use Bria Guided Remove Background

Bria Guided Remove Background turns a plain-English prompt into a precise cutout. Send an image plus a short instruction that names what to keep or drop, and the model returns a true-alpha PNG at the original resolution with the original pixels untouched. Leave the prompt blank and it falls back to a standard one-click removal.

How it works

The prompt steers Bria's RMBG-2.0 cutout in one of a few ways:

• •Narrow to one object: only the red accordion.
• •Drop a named element the default keeps: the accordion player without the dog.
• •Add an item the default misses: the person with the mat and the plant.
• •Blank prompt: a standard full-foreground removal.

Recommended Settings

• •image: the highest-resolution original you have (public URL or base64 data URI; JPEG, PNG, or WEBP). Cleaner inputs give cleaner mattes.
• •prompt: name the target by a distinctive attribute (color + object type) for reliable results; keep it to the one action you want.
• •preserve_alpha: leave true to retain soft hair and fur edges and any partial transparency the input already carries; set false to flatten kept pixels fully opaque.
• •visual_input_content_moderation / visual_output_content_moderation: leave false for trusted assets; enable when screening user-supplied uploads or serving public pipelines.

Example cuts to try

Each example below ran end to end on the same source image at the settings shown — only the prompt changed — and each returned a true-alpha PNG at the original resolution, so you can see one frame cut four different ways.

• •Narrow to one object. Prompt: "only the red accordion". The output isolates just the accordion on transparency, dropping the man, dog, crate, and hat. Tip: name the target by color plus type for a dependable narrow.
• •Drop a named element. Prompt: "the accordion player without the dog". Keeps the man, accordion, crate, and hat but removes only the terrier. Tip: phrase it "the <subject> without the <thing>" to subtract one element while keeping the rest.
• •Narrow to a soft-edged subject. Prompt: "only the dog". Pulls out just the terrier with clean wiry-fur edges. Tip: keep preserve_alpha on so hair and fur stay soft.
• •Standard cutout. Prompt: "" (blank). Returns the full one-click RMBG-2.0 foreground. Tip: use an empty prompt when you only need a plain removal, then add words to override what it keeps.

Other instructions the model is built for: "only the chair", "the woman at her desk without the lamp", "the product with its box", "the cyclist without the water bottle".

Does it repaint or alter my image?

No. It adds only an alpha channel at the original resolution; kept pixels are untouched.

What does the prompt actually do?

It decides what the cutout keeps — add, drop, or narrow the foreground. Blank returns a standard removal.

What format is the output?

A transparent true-alpha PNG, ready for compositing.

Can it keep soft hair and fur edges?

Yes. RMBG-2.0 produces sub-pixel mattes; keep preserve_alpha enabled to retain them.

What image types can I send?

A public image URL or a base64 data URI in JPEG, PNG, or WEBP.

What languages does the prompt support?

Prompt guidance is in English.
