PNG output sizes at 2×
Every pixel becomes a 2 × 2 block of 4 new pixels, filled in by the AI model instead of copied. File sizes are estimates for PNG output.

About Portable Network Graphics files
Lossless and supports transparency, so the alpha channel is kept through the upscale.
Output is written as PNG, JPG or WEBP. For PNG input, PNG is the closest match.

Questions
Is upscaling PNG 2× free?
Yes. The free plan includes 5 upscales a day at 2×, with no watermark and no account needed.
Does my PNG file upload anywhere?
No. At 2× the image is decoded and enlarged inside your browser, and the file never leaves your device.
How big is a PNG after 2× upscaling?
Width and height both grow 2 times, so the pixel count grows 4 times. A 1920 × 1080 image becomes 3,840 × 2,160, about 16 MB as PNG.
Is PNG transparency kept?
Yes, on your device (2× and 4×). The model upscales the colour and the alpha channel is enlarged separately and put back, so a transparent background stays transparent as long as you export PNG or WEBP. JPG has no transparency and gets a white background.
When is 2× not enough?
When you need a print or a 4K screen from a small image. A 640 × 480 file only reaches 1280 × 960 at 2×. Check the print size chart to see the pixels you need.
