How to use this tool
- Choose your photograph, or drag it onto the box above. It is cropped to fill 1200 × 627 px from the centre — never stretched, so faces keep their proportions.
- There is nothing to set. This page is already fixed at 1200 × 627 px, under 1.00 MB, JPEG.
- It crops to exactly 1200 × 627 px without stretching anything, then adjusts quality until the file fits.
- Check the output dimensions read exactly 1200 × 627 px, then download. If the size limit could not be met at those fixed dimensions, the panel says so rather than quietly shrinking the image.
Social platforms crop the same image differently across desktop, mobile and app surfaces. Getting the dimensions right is the easy half; keeping important content out of the crop zones is the half people miss.

LinkedIn Post Image — 1200 × 627: why uploads get rejected
Getting under the limit is the easy half. The 1200 × 627 pixel box has to be right as well, and several other things are checked before a human sees the file:
- A square image is letterboxed in the feed.
How it works
Hitting a size limit exactly is a search problem, not a setting. There is no quality value that means “1.00 MB” — how many bytes a given quality produces depends entirely on the picture. So this tool encodes, measures the real file, and adjusts.
Here the dimensions are fixed at 1200 × 627 px by the specification, so scaling is not available as a lever. Everything has to come from the quality setting, and the tool reports honestly when the two requirements cannot both be met.
Where the first attempt already fits — as it did on the reference file below, at 219.3 KB — the search stops immediately rather than compressing further for no reason.
The crop, the resize and every encode happen on your own device through the browser’s canvas API. A photograph for an official form is not a file worth handing to someone else’s server, and this page never receives it.
A measured run of this exact preset
Not an estimate: this page’s own code, run against a 12.2 MP photograph and an A4 scan at 200 dpi, with every encode recorded. The files and the method are published here.
| Input | Result | Change | Outcome |
|---|---|---|---|
| 12.2 MP photograph 3024 × 4032 px · 2.94 MB | 219.3 KB 1200 × 627 px | 93% smaller | Under the 1.00 MB limit |
| A4 scan at 200 dpi 1654 × 2339 px · 996.0 KB | 266.8 KB 1200 × 627 px | 73% smaller | Under the 1.00 MB limit |
Step by step
The dimensions here are fixed by the specification (1200 × 627 px), so the image cannot be scaled to help. The file size has to come from quality alone.
The first attempt, at quality 0.96, produced 219.3 KB — already inside the 1.00 MB allowance, so no search was needed. One encode and it was done.
Final file: 219.3 KB, using 21.4% of the allowance, with 804.7 KB to spare.
Who needs LinkedIn Post Image — 1200 × 627
Anyone preparing images for this placement who wants the exact dimensions rather than an approximation that gets cropped or scaled by the platform.
LinkedIn Post Image — 1200 × 627 — frequently asked questions
What are the correct dimensions?
1200 × 627 pixels. This tool outputs exactly that.
Why does my image get cropped?
Platforms display the same upload at different ratios depending on the surface — desktop, mobile web, and app all differ. Keep essential content away from the edges.
Does the platform re-compress my image?
Almost always. Starting from a correctly sized, good-quality file gives the best final result, because it avoids a resize stacked on top of a re-encode.
Why does the output have a white background?
Transparency cannot survive as JPEG, so transparent areas are filled rather than turned black. White is what forms and ID photos expect. If you need transparency kept, use a PNG tool instead.
Which file types can I upload?
JPG, PNG, WebP, GIF, BMP and HEIC from an iPhone all go in. The output here is JPEG. Conversion happens as part of the process, so there is no need to convert first.
Does this work on a phone?
Yes, including photos straight from your camera roll. The work happens on the device, so a very large image is slower on a phone than on a laptop, but nothing is uploaded either way.
