Make small or blurry images bigger and sharper. Our AI model rebuilds detail as it enlarges your photo 2× or 4×, all inside your browser.
Make small, low-resolution or slightly blurry photos bigger and sharper. DoraPDF's AI upscaler (based on the ESRGAN super-resolution model) rebuilds fine detail as it enlarges your image 2× or 4× — far better than simply stretching it. Everything runs in your browser, so your photos stay on your device.
Normal resizing just stretches pixels, so the result looks soft. AI upscaling predicts the missing detail, giving sharper edges, cleaner text and more natural textures.
AI upscaling is heavy work done on your own device. Smaller images and 2× are fastest; for very large images use Fast mode.
AI mode supports outputs up to about 6000 pixels on the long side. Fast mode works on any size.
