Before and after
Upscaling versus resizing
Print sizes are for a 4:3 phone photo at 300 dpi.
- Resizing
- Spreads the pixels you already have over a bigger canvas. The photo gets larger and softer, and diagonal edges turn into steps.
- AI upscaling
- Draws new detail at the target size: strands of hair, lashes, skin and fabric that hold up when you zoom in.
- 2K
- 1,920 × 1,440 pixels, a sharp print at about 6 × 5 in (16 × 12 cm).
- 4K
- 2,880 × 2,160 pixels, a sharp print at about 10 × 7 in (24 × 18 cm).
- 8K
- 5,760 × 4,320 pixels, a sharp print at about 19 × 14 in (49 × 37 cm).

Questions about the image upscaler
Which size should I pick?
4K suits most uses: screens, social posts and photo prints. Pick 8K for large prints or heavy cropping, and 2K when the photo is going on the web.
What do 2K, 4K and 8K mean?
The length of the photo's short side: about 1,440, 2,160 and 4,320 pixels. The long side follows the photo's own shape. A size your photo already reaches is greyed out.
Can I upscale several photos at once?
Yes, up to 50 in one run, all at the size you pick. Each result has its own download button, and Download all saves every one.
How much does an upscale cost?
8 swapz for 2K, 15 for 4K and 30 for 8K, per photo. The total shows on the button before you start, and a photo that fails is not charged.
Can I try it for free?
Yes. A new account gets 30 free swapz to spend on upscales or face swaps.
How long are my photos kept?
Upscaled photos stay in your account for 30 days after they finish. Download the ones you want to keep.
