Resize an image to 2048×1536 pixels (QXGA)
To resize an image to 2048×1536 px, enter 2048 × 1536 px and pick crop to fill so the 4:3 frame is not stretched: a 4:3 phone photo already has this shape and is only scaled by 0.508×. The result has 3.15 megapixels; as a JPEG, a detailed outdoor photo is about 1,024 KB at the panel's default quality 85 (777 KB at quality 75).

What 2048×1536 means in pixels
2048×1536 is a landscape frame, 1.33 times as wide as it is tall, 3,145,728 pixels in total (3.15 megapixels). Its sides reduce to 4:3 (1.3333 as a decimal), so any picture cropped to 4:3 scales to it without distortion.
That is 25.8% of a 12 MP phone frame; after the crop to fill the phone picture is reduced by 0.508×, so fine detail such as hair and text survives. Shown 1:1 it fills 2048×1536 CSS px on a standard screen and 1024×768 CSS px on a 2× (Retina-class) screen; at 72 DPI the same pixels span 28.4×21.3 inches.
Decoded for editing it occupies 12 MB of memory (4 bytes per pixel); uncompressed 24-bit RGB would be 9 MB, which is why the downloadable JPEG, PNG or WebP is far smaller.

Getting 2048×1536 from a phone, camera or screenshot
Filling 2048×1536 from a 12 MP phone photo (4032×3024, 4:3) loses nothing; a vertical phone video frame (1080×1920, 9:16) loses the most (57.8%). "Fit inside" keeps the whole picture instead and the file comes out at the size in the last column; "Pad with colour" adds bars to reach the full 2048×1536.
| Starting image | Crop to fill keeps | Area lost | Scale | Fit inside gives |
|---|---|---|---|---|
| 12 MP phone photo (4032×3024, 4:3) | 4032×3024 (nothing cut) | 0% | 0.508× (reduced) | 2048×1536 |
| 24 MP camera photo (6000×4000, 3:2) | 5333×4000 (left and right cut) | 11.1% | 0.384× (reduced) | 2048×1365 |
| Full HD screenshot (1920×1080, 16:9) | 1440×1080 (left and right cut) | 25% | 1.422× (enlarged) | 2048×1152 |
| Vertical phone video frame (1080×1920, 9:16) | 1080×810 (top and bottom cut) | 57.8% | 1.896× (enlarged) | 864×1536 |
When 2048×1536 means enlarging
After the crop to fill, the kept region has to be enlarged 1.422× from a Full HD screenshot and 1.896× from a vertical phone video frame. Enlarging adds pixels but no detail, so start from the largest original you have, or choose a smaller target if the destination allows it: 6×4 inch print or 1920×1200 (WUXGA) would need less stretching.
