Facebook Image Resizer
Crop to the 1200 x 630 the Facebook feed is built around, or to 1080 x 1920 for a Story, and stay under the 4 MB ceiling that rejects more Facebook uploads than anything else.
Last updated: 2026-08-03
Facebook renders a shared link preview at 1.91:1, which is where 1200 x 630 comes from, and it keeps whatever ratio you upload for a photo post. The result is that the same file can appear in two completely different shapes depending on how it is posted, and the only way to control that is to export the frame you actually want.
The number that catches people out is not the resolution, it is the 4 MB file size cap on a post image. That is the lowest ceiling of any network here, less than half of Instagram at 8 MB and a fifth of Pinterest at 20 MB, and a detailed PNG at 1200 x 630 goes past it without trying.
This resizer crops to the frame you pick, keeps the subject where you point it, and gives you a quality slider so you can land under 4 MB deliberately rather than by trial and error. It runs in your browser and nothing is uploaded.
Your image never leaves your browser. The crop and the export both run on your device, and nothing is uploaded to us. HEIC photos straight from an iPhone only decode in Safari, so export a JPEG copy first if yours will not open.
Facebook sizes to export
Each one is cropped to fill the frame, centered on the focus point you pick.
Focus point
What every crop stays centered on when the shapes do not match.
Focus: Center
Export format
0.85 is the safe default. Push to 0.95 for images with text, drop toward 0.7 only when you are fighting a tight file size cap.
Re-encoding through canvas also drops the EXIF block, so the file you download carries no GPS coordinates, camera model or timestamp.
Facebook image sizes
Every Facebook surface that takes a still image, with the size to export at and the ceiling the file has to stay under.
| Surface | Export at | Aspect ratio | Max file size | File types |
|---|---|---|---|---|
| Feed image | 1200 x 630 | 1.91:1 | 4 MB | JPG, PNG |
| Story | 1080 x 1920 | 9:16 | 100 MB | MP4, MOV, JPG, PNG |

JPEG or PNG, and what the quality slider does
The resolution decides whether your image fits the frame. The format and the quality setting decide whether it fits the file size cap, and those are two different problems.
JPEG
Photographs, screenshots of video, anything with gradients
Lossy, and that is the point: a 1080 pixel wide photo lands between 100 KB and 500 KB at quality 0.85, which clears every file size cap on this page with room to spare. The artifacts it introduces hide well in detail and texture.
PNG
Logos, charts, diagrams, screenshots of text, flat color
Lossless, so text stays crisp and flat areas stay flat. The cost is size: the same image can be five to ten times larger than the JPEG, which is what pushes a thumbnail past 2 MB or a Facebook image past 4 MB.
The quality slider only applies to JPEG, and it runs from 0.6 to 1.0. At 0.85, the default here, the difference from the original is invisible at normal viewing size on almost any photograph. Above 0.95 the file grows quickly for very little gain. Below about 0.75 you start to see blocking in skies and other large flat areas, which is the first thing that gives away an over-compressed image.
One thing worth knowing either way: every network re-compresses what you upload. Exporting at maximum quality does not protect the detail, it just means the image is compressed twice. A clean file at the recommended size and a sensible quality survives that better than an enormous one.
Facebook image tips
- Export at 1200 x 630 for anything that will be seen as a link preview. That is exactly 1.91:1, and it is the frame Facebook designed the feed card around.
- Watch the 4 MB cap. JPEG at quality 0.85 keeps a 1200 x 630 photo well under 1 MB; the same image as PNG can be four or five times that and get rejected outright.
- A photo post keeps your aspect ratio, so a portrait image really does take more vertical space in the feed. Use that deliberately rather than defaulting to landscape.
- Stories are 1080 x 1920 and get cropped hard on tall phones. Keep anything important away from the outer 10 percent of the frame on every side.
- Do not reuse the same file for the feed and for a Story. 1.91:1 placed on a 9:16 canvas leaves two thirds of the screen empty or forces a crop that loses the sides.
- If you also publish the post to Instagram, export twice. Facebook is happiest landscape at 1200 x 630 and Instagram is happiest portrait at 1080 x 1350, and neither is a good substitute for the other.
Frequently asked questions
What size should a Facebook post image be?
For the feed and for link previews, 1200 x 630 pixels at 1.91:1, under a 4 MB file size cap. For a Story, 1080 x 1920 at 9:16, where the cap is a much more generous 100 MB. Photo posts accept any ratio between roughly 9:16 and 1.91:1.
Is my image uploaded when I use this resizer?
No. The file is decoded and redrawn in your browser with canvas, and the resized copy goes straight to your downloads. Nothing is sent to our servers and nothing is sent to Facebook until you post it yourself.
Why does my HEIC photo not open in this tool?
HEIC is the format iPhones save by default and most browsers cannot decode it, so the tool has no pixels to work with. Export a JPEG copy from Photos, or set Settings, Camera, Formats to Most Compatible. Facebook itself only accepts JPG and PNG for a post image anyway.
Does resizing remove EXIF and GPS data?
Yes. The output is encoded from a fresh canvas, so it carries no EXIF block: location, camera model and timestamp are all dropped. Facebook strips most metadata on its side too, but the resized file is already clean before it leaves your machine.
Will the quality drop when I resize for Facebook?
Some, because Facebook re-compresses uploads regardless. Give it a clean, correctly sized JPEG at quality 0.85 or higher and the result holds up well. Uploading something enormous does not help: it just means your file is compressed twice, once by you and once by Facebook.
Why does Facebook keep rejecting my image?
The 4 MB post image cap is by far the most common reason. A large PNG or a full resolution camera JPEG will exceed it. Resize to 1200 x 630, export as JPEG, and the file will typically land between 150 KB and 800 KB.
