Resize an image to 1366×768 pixels (WXGA)
To resize an image to 1366×768 px, enter 1366 × 768 px and pick crop to fill so the 683:384 (about 16:9) frame is not stretched: a 4:3 phone photo loses 25% of its area (a centred 4032×2267 crop). The result has 1.05 megapixels; as a JPEG, a detailed outdoor photo is about 356 KB at the panel's default quality 85 (270 KB at quality 75).

What 1366×768 means in pixels
1366×768 is a landscape frame, 1.78 times as wide as it is tall, 1,049,088 pixels in total (1.05 megapixels). Its sides only reduce to 683:384; that is exactly the familiar 16:9 shape, so a 16:9 crop needs only a sliver trimmed to land on exactly 1366×768.
A 12 MP phone photo has 12 times as many pixels, so reaching 1366×768 is a clean reduction with no invented detail. Shown 1:1 it fills 1366×768 CSS px on a standard screen and 683×384 CSS px on a 2× (Retina-class) screen; at 72 DPI the same pixels span 19×10.7 inches.
Decoded for editing it occupies 4 MB of memory (4 bytes per pixel); uncompressed 24-bit RGB would be 3 MB, which is why the downloadable JPEG, PNG or WebP is far smaller.

Getting 1366×768 from a phone, camera or screenshot
Filling 1366×768 from a Full HD screenshot (1920×1080, 16:9) loses nothing; a vertical phone video frame (1080×1920, 9:16) loses the most (68.4%). "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 1366×768. From the phone photo PixelFit takes the 4032×2267 crop through 2016×1133 before the last step to 1366×768, 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) | 4032×2267 (top and bottom cut) | 25% | 0.339× (reduced) | 1024×768 |
| 24 MP camera photo (6000×4000, 3:2) | 6000×3373 (top and bottom cut) | 15.7% | 0.228× (reduced) | 1152×768 |
| Full HD screenshot (1920×1080, 16:9) | 1920×1080 (nothing cut) | 0% | 0.711× (reduced) | 1365×768 |
| Vertical phone video frame (1080×1920, 9:16) | 1080×607 (top and bottom cut) | 68.4% | 1.265× (enlarged) | 432×768 |
When 1366×768 means enlarging
After the crop to fill, the kept region has to be enlarged 1.265× 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: 1280×720 (HD) or 1280×800 (WXGA) would need less stretching.
How many KB is a 1366×768 image?

How to resize a picture to 1366×768
-
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 1366 as the width and 768 as the height in pixels (the panel is already set to 1366×768).
-
Choose how it fits
Choose crop to fill to keep the 683:384 (about 16:9) frame without stretching (a phone photo loses 25%, top and bottom cut). Fit inside keeps the whole picture as a 1024×768 file instead; Pad with colour puts that on a full 1366×768 canvas.
-
Pick the format and download
Choose JPG or WebP; without a KB limit PixelFit saves JPG at quality 85, about 356 KB for a detailed outdoor photo. Add a KB limit if the upload has one or the file should be smaller, then download the 1366x768 file.
