What the LinkedIn Banner Maker does
LinkedIn Banner Maker: outputs exactly 1584x396 px, the size LinkedIn uses for profile banners. Everything runs in your browser and the file is never uploaded.
The LinkedIn Banner Maker works on a file you choose, without sending it anywhere. The work happens inside your browser tab, so there is no upload to wait for and no queue.
Typical users are people preparing images for the web. A smaller file that still looks right is usually only a few settings away.
There is no account, no upload and no server round trip, because the page does the work itself.
If you want to check the arithmetic, the field table, the method and a worked example are further down.
What do the LinkedIn Banner Maker fields mean?
The LinkedIn Banner Maker uses 3 inputs. You can work from the defaults, or clear them and start fresh, both work.
| Field | What to enter | Default |
|---|---|---|
| Image file | stays on your device | none |
| Export as | choose from PNG, JPEG or WebP | JPEG |
| Quality % | accepts 10 to 100 | 90 |
How does the LinkedIn Banner Maker work?
Each output is derived from the inputs above in a single pass; there is no hidden state carried between runs, so the same inputs always give the same generated output.
The guard clauses run before the formula does, which is why mistakes surface next to the field.
What a typical run looks like
You provide: Image file, Export as and Quality %
What happens: the file is read into memory by your browser, processed locally, and offered back as a download. It is never uploaded.
You get back: a download link for the new file and a short note on what changed.
Timing comes down to your own hardware, and the practical size limit is how much memory the browser will hand the tab.
LinkedIn banners sizes
LinkedIn uses a 4:1 banner on personal profiles and a different ratio on company pages. As on Facebook, the profile photo overlaps the banner and the overlap position differs between desktop and mobile.
| Use | Size | Ratio |
|---|---|---|
| Personal profile banner | 1584 × 396 | 4:1 |
| Company page banner | 1128 × 191 | 5.9:1 |
| Profile photo | 400 × 400 | 1:1 |
| Company logo | 300 × 300 | 1:1 |
| Shared post image | 1200 × 627 | 1.91:1 |
Worth knowing
- The profile photo covers the lower-left on desktop and is centred lower on mobile. The reliably safe zone is the upper-right two thirds.
- Company page banners are much shorter proportionally. A personal banner reused on a company page will be cropped heavily.
- File size limit is 8 MB, which is generous enough that quality is rarely the constraint.
- Text in a banner is often illegible on mobile. Treat it as a visual, not a message.
Platforms revise their published specifications from time to time. Where a ratio and a pixel size conflict, match the ratio — every platform downscales an oversized image, but none of them will fix a wrong shape except by cropping it.
How to use it
- Choose your file under Image file, or drag it onto the drop area.
- Pick a value for Export as: the options are PNG, JPEG or WebP.
- Enter Quality % (10 to 100).
- Press Create.
- The panel reports Status.
- Copy Link is the quickest way to send the exact scenario to someone else.
What this tool does not do
- EXIF metadata may be dropped during processing, which is usually desirable but is worth knowing.
- Re-encoding a lossy format such as JPEG always loses some detail, even at maximum quality.
- There is no audit trail: if you need one, record the inputs alongside the output.
- The tool cannot tell whether a number was entered in the unit you intended, so double-check the labels.
- Large files are limited by your available memory, not by an upload quota.
Frequently asked questions
Image file, Export as and Quality %. That is the whole form. Nothing starts empty, letting you treat it as a what-if tool rather than a data-entry form.
Quality % accepts 10 to 100. If a value falls outside, the tool says which field is at fault instead of guessing.
It is not uploaded. Everything happens on your device, so no copy of your file exists on any server.
Nothing at all. There is no registration, no paywall and no per-use quota.
Reliable for the case described. Where more than one convention exists, the method section says which one is used.
