The target here is 4000 × 800 px: a landscape (wide) 5:1 image of 3.2 megapixels. The preset fills in both dimensions for you, so you only need to add the photo and download the result.

Because the output size is fixed, the photo's own shape matters: if it is not 5:1, you either crop it or it gets distorted. The table below shows how much each common photo shape loses.

Output size	4000 × 800 px
Aspect ratio	5:1 (landscape)
Total pixels	3,200,000 (3.2 MP)
Prints at 300 DPI	13.3 × 2.7 in (33.9 × 6.8 cm)

Fitting a photo into 4000 × 800 px

Resizing to a fixed width and height only gives a clean result when the photo has the same shape as the target. A shape mismatch has two outcomes: the picture is stretched, or part of it is cropped. Crop first, then resize, so you decide what is cut. This is how much of each common photo would be lost to fill 5:1:

Starting photo	Cropped away to fill the shape
Phone photo (4000 × 3000, 4:3)	About 73% of the image
DSLR photo (6000 × 4000, 3:2)	About 70% of the image
Video frame (1920 × 1080, 16:9)	About 64% of the image
Portrait phone photo (3000 × 4000, 3:4)	About 85% of the image

Size, quality and file weight

3,200,000 pixels saved as a JPG at web quality typically weigh about 312.5 KB to 937.5 KB, depending on how much detail the picture contains. Flat graphics and screenshots saved as PNG compress very well when colors are simple, and poorly when they contain photographic gradients.

For photos, JPG or WebP are good choices; for logos, text or transparency, PNG keeps edges clean.

How large can it be printed?

These figures follow from the pixel count: print size = pixels ÷ DPI. Going above the 300 DPI row gives no visible benefit; going below it looks softer.

Quality	DPI	Print size
Screen-resolution draft	72	55.6 × 11.1 in (141.1 × 28.2 cm)
Acceptable for posters	150	26.7 × 5.3 in (67.7 × 13.5 cm)
Photo quality	300	13.3 × 2.7 in (33.9 × 6.8 cm)

How to resize an image to 4000x800 px

Add your image. Select a photo or drag it onto the box above. JPG, PNG, WebP, AVIF, HEIC and BMP files are accepted, and the file stays on your device.
Crop to 5:1 (recommended). The output is 4000 × 800 px, a 5:1 shape. Cropping to that shape first with the built-in Crop tool decides what stays in frame and avoids distortion.
Confirm the size and format. The preset fills in 4000 × 800 px. Choose JPG for photos or PNG for graphics with sharp edges or transparency.
Download the resized image. Click resize and save the file. The result uses Lanczos-3 resampling, which keeps edges clean when scaling down.

Frequently asked questions

How do I resize an image to 4000x800 px without stretching it?▼

Crop the photo to 5:1 first (the built-in Crop tool does this), then apply the preset. If you skip the crop and your photo has a different shape, the result is either stretched or cut off. For example, a 4:3 phone photo needs about 73% of its area cropped to become 5:1.

What aspect ratio is 4000 × 800?▼

5:1, landscape. It has 3.2 megapixels. The width is 5 times the height.

How big will a 4000 × 800 file be?▼

As a JPG at web quality, usually between 312.5 KB and 937.5 KB; photographic PNGs are several times larger. To fit a specific limit, use one of the file-size presets after resizing, or set a target size in the editor.

What if my photo is smaller than 4000 × 800?▼

The tool will enlarge it, but enlarging cannot add detail, so the result looks soft. Starting from a photo at least as large as 4000 × 800 gives a much sharper result.

Which format should I use for 4000 × 800?▼

JPG or WebP for photographs; PNG for graphics, screenshots and anything with transparency. AVIF can be smaller still, but it encodes more slowly and some older apps cannot open it.

How large can I print a 4000 × 800 px image?▼

About 13.3 × 2.7 in (33.9 × 6.8 cm) at 300 DPI (photo quality) and 26.7 × 5.3 in (67.7 × 13.5 cm) at 150 DPI (acceptable for posters viewed from a distance).

Do I need an account, and does it add a watermark?▼

No account and no watermark. Open the page, add your photo, and download the result. Because processing happens on your own device, there is no queue and nothing to wait for, even with a large original.
