Resize an image to 600×400 pixels
To resize an image to 600×400 px, enter 600 × 400 px and pick crop to fill so the 3:2 frame is not stretched: a 4:3 phone photo loses 11.1% of its area (a centred 4032×2688 crop). The result has 0.24 megapixels; as a JPEG, a detailed outdoor photo is about 81 KB at the panel's default quality 85 (60.5 KB at quality 75).

What 600×400 means in pixels
600×400 is a landscape frame, 1.5 times as wide as it is tall, 240,000 pixels in total (0.24 megapixels). Its sides reduce to 3:2 (1.5 as a decimal), so any picture cropped to 3:2 scales to it without distortion.
A 12 MP phone photo has 51 times as many pixels, so reaching 600×400 is a clean reduction with no invented detail. Shown 1:1 it fills 600×400 CSS px on a standard screen and 300×200 CSS px on a 2× (Retina-class) screen; at 72 DPI the same pixels span 8.3×5.6 inches.
Decoded for editing it occupies 938 KB of memory (4 bytes per pixel); uncompressed 24-bit RGB would be 703 KB, which is why the downloadable JPEG, PNG or WebP is far smaller.
Getting 600×400 from a phone, camera or screenshot
Filling 600×400 from a 24 MP camera photo (6000×4000, 3:2) loses nothing; a vertical phone video frame (1080×1920, 9:16) loses the most (62.5%). "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 600×400. From the phone photo PixelFit takes the 4032×2688 crop through 2016×1344 and 1008×672 before the last step to 600×400, 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) | 4032×2688 (top and bottom cut) | 11.1% | 0.149× (reduced) | 533×400 |
| 24 MP camera photo (6000×4000, 3:2) | 6000×4000 (nothing cut) | 0% | 0.1× (reduced) | 600×400 |
| Full HD screenshot (1920×1080, 16:9) | 1620×1080 (left and right cut) | 15.6% | 0.37× (reduced) | 600×338 |
| Vertical phone video frame (1080×1920, 9:16) | 1080×720 (top and bottom cut) | 62.5% | 0.556× (reduced) | 225×400 |

| Resolution | Print size (inches) | Print size (cm) |
|---|---|---|
| 72 DPI | 8.33×5.56 in | 21.2×14.1 cm |

How to resize a picture to 600×400
-
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 600 as the width and 400 as the height in pixels (the panel is already set to 600×400).
-
Choose how it fits
Choose crop to fill to keep the 3:2 frame without stretching (a phone photo loses 11.1%, top and bottom cut). Fit inside keeps the whole picture as a 533×400 file instead; Pad with colour puts that on a full 600×400 canvas.
-
Pick the format and download
Choose JPG or WebP; without a KB limit PixelFit saves JPG at quality 85, about 81 KB for a detailed outdoor photo. Add a KB limit if the upload has one or the file should be smaller, then download the 600x400 file.

Frequently asked questions
How do I resize an image to 600x400?
Open the image in the PixelFit panel on this page, set 600 × 400 px, choose crop to fill so nothing is stretched and download. From a 12 MP phone photo that crops 11.1% (top and bottom cut) and scales the rest by 0.149×.
What aspect ratio is 600x400?
600x400 has an aspect ratio of 3:2: landscape, width ÷ height = 1.5. Sizes with the same ratio include 900×600 landscape, 1200×800 landscape and 300×200 landscape.
Is 600x400 good for print?
At 300 DPI 600x400 prints 2×1.33 in (5.1×3.4 cm). At 150 DPI it stretches to 4×2.67 in.
How big is a 600x400 JPEG file?
For a detailed outdoor photo about 60.5 KB at quality 75 (45.2 KB at 60, 99 KB at 90, 81 KB at the panel's default quality 85); a head-and-shoulders portrait is about 33.4 KB at quality 75, estimated from measured encodes. A flat graphic is smaller, a noisy low-light photo larger.
How does 600x400 look on a high-density screen?
On a 2× screen 600x400 is sharp when shown at 300×200 CSS px; shown larger, the browser enlarges it. A slot of 600×400 CSS px on a 2× screen needs a 1200×800 file.
