This preset resizes any image to exactly 851 × 315 px. The output is a landscape (wide) 2.7:1 frame of 268,065 pixels in total (0.27 megapixels), which counts as a small image by photo standards.
The preset is named for Facebook. It outputs exactly 851 × 315 px; platforms change what they recommend from time to time, so confirm the current figure in Facebook's own help pages if exact compliance matters.

Fitting a photo into 851 × 315 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 2.7:1:
| Starting photo | Cropped away to fill the shape |
|---|---|
| Phone photo (4000 × 3000, 4:3) | About 51% of the image |
| DSLR photo (6000 × 4000, 3:2) | About 44% of the image |
| Video frame (1920 × 1080, 16:9) | About 34% of the image |
| Portrait phone photo (3000 × 4000, 3:4) | About 72% of the image |
Size, quality and file weight
268,065 pixels saved as a JPG at web quality typically weigh about 26.18 KB to 78.53 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 | 11.8 × 4.4 in (30 × 11.1 cm) |
| Acceptable for posters | 150 | 5.7 × 2.1 in (14.4 × 5.3 cm) |
| Photo quality | 300 | 2.8 × 1.1 in (7.2 × 2.7 cm) |
About the Facebook preset
ResizeAny sets the output to 851 × 315 px and nothing else. It does not know which placement or account type you are using, and Facebook may crop, recompress or re-scale an upload on its side. Keep important content away from the edges, and check Facebook's current guidelines for the placement you are working on.
