Rebuild instead of stretch
Basic resizing repeats existing pixels. PhotoBoost analyzes the image and reconstructs detail as it increases resolution, helping the result stay clear at a larger size.
AI image upscaler
Upscale images up to 4× without settling for blurry pixels.
PhotoBoost increases image resolution while rebuilding useful detail in faces, textures and edges. Turn a small or heavily cropped photo into a clearer, higher-resolution image directly in your browser.

AI Image Upscaler FAQs
How much can PhotoBoost upscale an image?
PhotoBoost can increase image resolution by up to 4×. The useful final size depends on the quality, focus and compression of the source photo.
Can I upscale an image without losing quality?
Every enlargement requires new pixels. AI upscaling is designed to reconstruct plausible detail instead of simply stretching pixels, but it cannot recover information that is completely absent from the source.
Which file formats can I upscale?
The PhotoBoost web app accepts JPG, JPEG, PNG, WebP and HEIC images up to 45 MB.
Does PhotoBoost replace my original image?
No. PhotoBoost creates a separate enhanced result for preview and download, leaving the original file unchanged.
