Resize an image to 1024×768 pixels (XGA)
To resize an image to 1024×768 px, enter 1024 × 768 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 0.254×. The result has 0.79 megapixels; as a JPEG, a detailed outdoor photo is about 264 KB at the panel's default quality 85 (199 KB at quality 75).

What 1024×768 means in pixels
1024×768 is a landscape frame, 1.33 times as wide as it is tall, 786,432 pixels in total (0.79 megapixels). Its sides reduce to 4:3 (1.3333 as a decimal), so any picture cropped to 4:3 scales to it without distortion.
A 12 MP phone photo has 16 times as many pixels, so reaching 1024×768 is a clean reduction with no invented detail. Shown 1:1 it fills 1024×768 CSS px on a standard screen and 512×384 CSS px on a 2× (Retina-class) screen; at 72 DPI the same pixels span 14.2×10.7 inches.
Decoded for editing it occupies 3 MB of memory (4 bytes per pixel); uncompressed 24-bit RGB would be 2.25 MB, which is why the downloadable JPEG, PNG or WebP is far smaller.

Getting 1024×768 from a phone, camera or screenshot
Filling 1024×768 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 1024×768. From the phone photo PixelFit takes the 4032×3024 crop through 2016×1512 before the last step to 1024×768, so each pass blends neighbouring pixels instead of skipping them.
| 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% | 0.254× (reduced) | 1024×768 |
| 24 MP camera photo (6000×4000, 3:2) | 5333×4000 (left and right cut) | 11.1% | 0.192× (reduced) | 1024×683 |
| Full HD screenshot (1920×1080, 16:9) | 1440×1080 (left and right cut) | 25% | 0.711× (reduced) | 1024×576 |
| Vertical phone video frame (1080×1920, 9:16) | 1080×810 (top and bottom cut) | 57.8% | 0.948× (reduced) | 432×768 |

Add the picture
Drop, paste or pick the photo in the PixelFit panel at the top of this page; it is decoded in your browser and never uploaded.
-
Set the size
Enter 1024 as the width and 768 as the height in pixels (the panel is already set to 1024×768).
-
Choose how it fits
Choose crop to fill: a 4:3 phone photo already matches, so nothing is cut.
-
Pick the format and download
Choose JPG or WebP; without a KB limit PixelFit saves JPG at quality 85, about 264 KB for a detailed outdoor photo. Add a KB limit if the upload has one or the file should be smaller, then download the 1024x768 file.
