Background removal used to require Photoshop, a professional designer, or an expensive subscription to tools like Adobe Firefly or Canva Pro. Today, AI-powered background removal runs entirely in your browser using machine learning models compiled to WebAssembly. Convifi removes backgrounds without uploading your image to any server — your photo processes on your own CPU or GPU, stays on your device, and the result downloads directly to you. No account, no subscription, no privacy compromise.
When You Need Background Removal
You'll reach for this more often than you'd expect:
- Product photography for e-commerce — white backgrounds are the standard on Amazon, Etsy, and Shopify
- Professional headshots for LinkedIn, company websites, or resumes
- Passport and ID photos requiring a plain white or light-grey background
- Creating PNG stickers or transparent-background logos for presentations
- Isolating a subject to composite them onto a new background for creative projects
- Removing distracting backgrounds from event photos before sharing
- Preparing photos for government forms that require a solid-colour background
How to Remove a Background Free — Step by Step
Convifi runs the AI locally in your browser — your photo never gets sent anywhere.
- Go to convifi.com/remove-bg
- Upload your image (JPEG or PNG, any size)
- The AI model downloads to your browser the first time (around 40 MB, cached after)
- The model processes the image locally on your device CPU/GPU — no upload
- Download the result as a PNG with a transparent background
What Types of Images Work Best
Results vary a lot depending on the photo:
- Works best: portraits with clear facial separation from background, product photos with good contrast, animals on simple backgrounds, objects on plain or lightly textured backgrounds
- Works reasonably: people with complex hairstyles (AI hair detection has improved dramatically), objects partially merged with background in colour
- Works less well: images where subject and background are very similar in colour/texture, transparent objects (glass, water), very busy backgrounds with similar tones as the subject
Hair and Fine Detail
Hair has historically been the hardest challenge for background removal AI — thousands of strands against a complex background is an extremely difficult segmentation problem. Modern models like the one used in Convifi handle hair surprisingly well in most cases. For the best hair results: good lighting that creates contrast between the hair and background makes a significant difference. Studio lighting or a window behind the camera typically produces clean edges.
After Removing the Background
Once you have the transparent PNG, common next steps:
- Add a solid white background: open in any image editor and fill the layer underneath with white — required for e-commerce and official documents
- Add a blurred or coloured background: works well for social media headers and creative profiles
- Resize and save at required dimensions: most passport portals require specific pixel dimensions
- Compress the resulting PNG: transparent PNGs can be large — use Convifi's compress tool to reduce the file size without quality loss
- Convert to JPEG if transparency is no longer needed: JPEG is smaller and more universally accepted
Privacy: Why It Matters for Background Removal
Any background removal service that runs on a server gets a copy of your photo. For headshots, ID documents, or family photos, that means personal data on someone else's server — and their privacy policy may let them use it for analytics or AI training. Convifi doesn't transmit anything. Not even a network request is made with your image data.
Performance on Mobile Devices
The AI model requires significant computing power. On modern iPhones and Android flagships (2022 onwards), processing typically takes 15–45 seconds per image. On older phones or budget devices, it may take 1–3 minutes or fail due to insufficient RAM. For mobile use, try the smallest image size that meets your quality requirements — a 1500px image processes much faster than a 4000px image. On desktop computers, processing is typically under 15 seconds.
