AI 사진 복원 4K - 오래된 사진을 울트라 HD 품질로 복원

AI Photo Restoration 4K uses advanced deep learning algorithms trained on millions of historical photos to automatically detect and repair damage with high-fidelity precision. The AI analyzes your photo to identify scratches, tears, stains, and fading, then intelligently reconstructs missing or damaged areas up to 4K ultra HD resolution. For colorization, it understands scene context, facial features, and historical color patterns to add natural, realistic colors to black and white photos in stunning 4K quality. The three restoration levels (Basic, Advanced, Professional) determine how extensively the AI processes your photo with high-fidelity output.

AI Photo Restoration can repair multiple types of damage with high-fidelity precision: scratches and surface marks, tears and rips in the photo, water stains and discoloration, faded or yellowed areas, missing corners or edges, creases and fold marks, dust spots and blemishes, and overall color degradation. All repairs are performed at up to 4K ultra HD resolution for exceptional detail. The Professional restoration level provides the most comprehensive high-fidelity repair, while Basic level handles common minor damage. For severely damaged photos, the Advanced or Professional levels with 4K output are recommended.

Yes! Our AI can automatically add natural, realistic colors to black and white photos in stunning 4K ultra HD resolution. The colorization option uses advanced algorithms that understand scene composition, skin tones, clothing styles, and historical context to apply appropriate colors with high-fidelity accuracy. You can choose from three color enhancement options: None (keeps original), Colorize (adds full color to B&W photos in 4K), or Enhance (improves existing colors in 4K). The AI has been trained on millions of historical photos to ensure accurate and believable colorization results in ultra HD quality.

Three high-fidelity restoration levels are available with 4K support: Basic (3 credits for 1K, 12 credits for 2K/4K) - removes scratches and noise, suitable for photos with minor damage, outputs in crisp 4K. Advanced (3 credits for 1K, 12 credits for 2K/4K) - repairs damage and enhances details with high fidelity, recommended for moderately damaged photos, ultra HD 4K output. Professional (3 credits for 1K, 12 credits for 2K/4K) - complete restoration with maximum AI enhancement and high-fidelity precision, ideal for severely damaged or important photos, premium 4K ultra HD output. All levels support up to 4K resolution for exceptional clarity.

You can restore photos at three resolutions: 1K (approximately 1024 pixels on the longest side), 2K (approximately 2048 pixels), or premium 4K ultra HD (approximately 4096 pixels). The actual dimensions maintain your original photo's aspect ratio. 1K is suitable for digital viewing and sharing, 2K works well for standard prints up to 11×14 inches, and 4K ultra HD is perfect for large prints, professional archival, and exceptional detail preservation. 4K provides 4× more detail than 1K and allows for stunning enlargements without quality loss. Higher resolutions cost more credits: 1K costs 3 credits, while 2K and 4K cost 12 credits each for premium quality.

Pricing varies by output resolution: 1K resolution costs 3 credits per photo (using Gemini 3 Pro model for high quality), while premium 2K and 4K ultra HD resolutions cost 12 credits per photo (using Nano Banana Pro model for exceptional high-fidelity quality). The restoration level (Basic/Advanced/Professional) and color enhancement option don't affect pricing—only the output resolution matters. 4K provides the best quality for professional work and large prints. New users receive free credits to try the 4K service. You can purchase additional credits through our flexible pricing plans without subscription requirements.

AI Photo Restoration 4K accepts JPEG and PNG image files. You can upload photos scanned from physical prints, existing digital photos, or images captured from old photo albums. For best 4K ultra HD results, scan physical photos at the highest quality your scanner supports (at least 600 DPI for 4K output, minimum 300 DPI). The maximum file size is 10MB. After restoration, you'll receive a high-fidelity 4K digital file that you can save, print at large sizes, or share with exceptional clarity.

Absolutely! The AI works on a digital copy of your photo—your original file is never modified. You'll receive the 4K ultra HD restored version as a new file while keeping your original intact. This allows you to compare before/after results at 4K quality and try different restoration settings if needed. We recommend always keeping your original files backed up in multiple locations for permanent preservation of your precious memories, and the 4K output provides an exceptional archival-quality digital copy.
