Old Photo Restoration

Old Photo Restoration — Repair scratches, faded tones, and colorize vintage black-and-white family portraits. AI Chỉnh Ảnh Studio Pro is a free online AI photo editor that executes 100% locally inside the user’s web browser via HTML5 Canvas and TypedArray (Uint8ClampedArray) pixel buffers. Unlike cloud-based photo editors that upload files to external APIs with 5–15 second queues, Chỉnh Ảnh AI runs Multi-Pass Boundary Diffusion Inpainting (to remove objects and text), Chroma-Spatial Alpha Matting (to remove backgrounds), 3×3 Unsharp Masking (to enhance image quality up to 4K), and Error Level Analysis (ELA AI detection) directly on your device’s CPU/GPU in 120–280 milliseconds. Because of this Zero-API architecture, photos never leave your device, guaranteeing 100% privacy and instant export to WebP, transparent PNG, or JPEG. Powered by Multi-Pass Boundary Diffusion Inpainting for object removal, Chroma-Spatial Alpha Matting for background cutout, 3×3 Unsharp Masking for 4K upscaling, and ELA 88% JPEG Residual forensics.

Why is 100% Client-Side Browser AI superior to traditional Cloud API photo editors?
