Resize an image to 5120×2880 pixels (5K)
To resize an image to 5120×2880 px, enter 5120 × 2880 px and pick crop to fill so the 16:9 frame is not stretched: a 4:3 phone photo loses 25% of its area (a centred 4032×2268 crop). The result has 14.7 megapixels; as a JPEG, a detailed outdoor photo is about 3.96 MB at the panel's default quality 85 (3 MB at quality 75, extrapolated).

What 5120×2880 means in pixels
5120×2880 is a landscape frame, 1.78 times as wide as it is tall, 14,745,600 pixels in total (14.7 megapixels). Its sides reduce to 16:9 (1.7778 as a decimal), so any picture cropped to 16:9 scales to it without distortion.
After the crop to fill a 12 MP phone photo (4032×3024) must be enlarged 1.27× to reach 5120×2880, which holds 1.2 times its pixels: no new detail appears, edges only get softer. Shown 1:1 it fills 5120×2880 CSS px on a standard screen and 2560×1440 CSS px on a 2× (Retina-class) screen; at 72 DPI the same pixels span 71.1×40 inches.
Decoded for editing it occupies 56.3 MB of memory (4 bytes per pixel); uncompressed 24-bit RGB would be 42.2 MB, which is why the downloadable JPEG, PNG or WebP is far smaller.

Getting 5120×2880 from a phone, camera or screenshot
Filling 5120×2880 from a Full HD screenshot (1920×1080, 16:9) loses nothing; a vertical phone video frame (1080×1920, 9:16) loses the most (68.3%). "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 5120×2880.
| Starting image | Crop to fill keeps | Area lost | Scale | Fit inside gives |
|---|---|---|---|---|
| 12 MP phone photo (4032×3024, 4:3) | 4032×2268 (top and bottom cut) | 25% | 1.27× (enlarged) | 3840×2880 |
| 24 MP camera photo (6000×4000, 3:2) | 6000×3375 (top and bottom cut) | 15.6% | 0.853× (reduced) | 4320×2880 |
| Full HD screenshot (1920×1080, 16:9) | 1920×1080 (nothing cut) | 0% | 2.667× (enlarged) | 5120×2880 |
| Vertical phone video frame (1080×1920, 9:16) | 1080×608 (top and bottom cut) | 68.3% | 4.741× (enlarged) | 1620×2880 |
When 5120×2880 means enlarging
After the crop to fill, the kept region has to be enlarged 1.27× from a 12 MP phone photo, 2.667× from a Full HD screenshot and 4.741× 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: 4096×2160 (DCI 4K) or 4000×3000 landscape would need less stretching.
How many KB is a 5120×2880 image?
Estimated from encodes of real sample images measured with sharp 0.35.5 / libvips 8.18.7 on 31 October 2026, interpolated to 14,745,600 pixels; this size lies outside the measured range, so the figures are extrapolated. The outdoor photo at 5120×2880 is about 3 MB at quality 75 and a scanned page about 1.14 MB; your file will differ with detail and noise.

How to resize a picture to 5120×2880
-
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 5120 as the width and 2880 as the height in pixels (the panel is already set to 5120×2880).
-
Choose how it fits
Choose crop to fill to keep the 16:9 frame without stretching (a phone photo loses 25%, top and bottom cut). Fit inside keeps the whole picture as a 3840×2880 file instead; Pad with colour puts that on a full 5120×2880 canvas.
-
Pick the format and download
Choose JPG or WebP; without a KB limit PixelFit saves JPG at quality 85, about 3.96 MB for a detailed outdoor photo. Add a KB limit if the upload has one or the file should be smaller, then download the 5120x2880 file.

Is 5120x2880 good for print?
At 300 DPI 5120x2880 prints 17.07×9.6 in (43.3×24.4 cm), enough for a print of that size at full density. At 150 DPI it stretches to 34.13×19.2 in.
How big is a 5120x2880 JPEG file?
For a detailed outdoor photo about 3 MB at quality 75 (2.3 MB at 60, 4.93 MB at 90, 3.96 MB at the panel's default quality 85); a head-and-shoulders portrait is about 1.07 MB at quality 75, extrapolated from encodes of real sample photos measured up to 6.75 MP (5120×2880 px lies outside that range). A flat graphic is smaller, a noisy low-light photo larger.
