Precise Subject Isolation — Portraits, Products & Pets

ImgGen's AI automatically identifies and isolates your subject — people, products, pets, or objects — and applies a natural depth-of-field blur to only the background pixels. Your subject stays razor-sharp while the background softens into a professional bokeh effect.

No manual masking, no selection tools, no Photoshop subscription. Upload your photo and get studio-quality background blur in under 5 seconds — free, with no watermark or quality loss.

Four Blur Intensity Levels — Full Creative Control

Choose from four preset intensity levels to match your creative vision: Subtle (30%) for natural-looking depth of field, Medium (60%) for classic portrait bokeh, Strong (80%) for dramatic subject separation, or Max (100%) for a fully cinematic, dreamy background.

Manual subject masking in Photoshop typically takes 10–20 minutes and requires layer skills most people don't have. ImgGen's AI detects edges and blurs in under 5 seconds — with no selection tools, no tutorials, and no subscription.

Frequently asked questions

How do I blur the background of a picture?

Upload your photo to ImgGen AI. The AI automatically detects your subject — person, pet, or product — and blurs only the background. Choose your blur intensity (Subtle, Medium, Strong, or Max) and download in seconds. No editing skills or software required.

What file formats are supported?

You can upload JPEG, PNG, and WEBP files up to 10 MB. Your blurred result is delivered in full resolution — no quality loss, no watermark — ready for sharing, printing, or posting on social media.

Can I remove the background instead of blurring it?

Yes. ImgGen also lets you remove the background entirely for a transparent PNG cutout, or replace it with a custom scene. Switch between blur, erase, and change modes without re-uploading your photo.

Is this background blur tool free?

Yes — the AI blur background tool is completely free to use. No watermarks, no quality loss, no account required. Upload your image and download a professional-looking blurred result immediately.

Can I blur backgrounds on my phone?

Yes. The tool runs entirely in your browser and works on iPhone, Android, tablets, and desktops — no app to download or install. Just open imggen.ai/tools/blur-background, upload from your camera roll, and save the result.

Can I adjust the blur intensity?

Yes. Choose from four preset levels: Subtle (30%) for natural-looking depth of field, Medium (60%) for classic portrait bokeh, Strong (80%) for dramatic subject separation, or Max (100%) for a fully dreamy, cinematic background blur.

How is AI background blur different from phone portrait mode?

Phone portrait mode uses on-device depth sensors and is limited to the moment of capture — you can't apply it later. ImgGen's AI blur works on any existing photo after the fact, with adjustable intensity and more precise subject masking. It also works on product photos, pet photos, and flat-lay images that phone portrait mode handles poorly.

How is this different from blurring a background in Photoshop?

In Photoshop, blurring a background requires manually selecting the subject (using Select Subject, layer masks, or the Blur Gallery), which can take 10–20 minutes and demands editing experience. ImgGen's AI does the same in under 5 seconds — fully automatically — with no software to install.

Does background blur affect image quality?

No. ImgGen processes your image at full resolution and applies the blur only to the background pixels. The subject remains pixel-sharp, and the final download is the same quality as your original upload — no compression artifacts or watermarks added.

Can I use background blur for product photos?

Yes. The AI detects objects, not just people, making it ideal for product photography. Blur the background on e-commerce shots to focus attention on the product and create a clean, studio-style look without renting a physical studio.
