HD, Full HD, and 4K
What converting a photo to HD means
HD describes a pixel count, not a filter. A photo counts as HD once it reaches about 1280 × 720 pixels. Smaller images look soft or blocky when you view them full screen, print them, or use them as a banner.
HD (720p)
1280 × 720 pixels · 0.9 MP
Full HD (1080p)
1920 × 1080 pixels · 2.1 MP
4K UHD (2160p)
3840 × 2160 pixels · 8.3 MP
Each output size multiplies the width and height of your photo. A 960 × 540 photo converted at 2x becomes 1920 × 1080, which is Full HD. The same photo at 4x becomes 3840 × 2160. Hover over a size in the converter to see the exact output dimensions before you convert.
Stretching a photo in an image editor only spreads the same pixels further apart, so the result stays blurry. The HD converter redraws edges, textures, and fine detail at the new size, so the HD version looks sharp at full screen.
Already have a large photo that still looks noisy or dull? Use the AI image enhancer to clean it up without changing the size.

Why convert photos to HD with Krea?
The HD photo converter increases the resolution of an image and rebuilds the detail that a larger size needs, so the result looks like it was shot in HD instead of stretched.

Convert to HD, Full HD, or larger

HD photo converter FAQ
An HD photo converter turns a low-resolution image into a high-definition one. It increases the pixel dimensions to HD (1280 × 720) or Full HD (1920 × 1080) and rebuilds the detail that the larger size needs, so the photo looks sharp instead of stretched.
Upload your photo, choose an output size (2x, 4x, or 8x), and click Generate. When the HD version is ready, compare it with the original and download it.
Yes. Pick the output size that brings your photo to at least 1920 × 1080. For example, a 960 × 540 image at 2x becomes exactly 1920 × 1080. Hover over each size option to see the result dimensions before you convert.
