Resize any image to 1584×396 px for LinkedIn banners. Free, no upload.
The preset makes a 1584 × 396 cover image — exactly 4:1 — which LinkedIn Help recommends for the profile cover (checked 2026-09-28), together with JPG or PNG and a file under 8 MB. LinkedIn also says the display changes with browser window size and screen resolution, but it publishes no safe zone, so none is claimed here. A 4:1 strip keeps only a third of a 4032 × 3024 photo's height (the middle 4032 × 1008), so choose the band carefully.

Making a game?
Nerulio is a 2D game asset studio first: draw pixel art, cut sprite sheets into animations, pack texture atlases, check autotile tilesets and export them for Godot, Unity, Phaser and other engines. It runs in your browser; files stay on your device.
4:1 is the widest of the presets. Fill and crop keeps the full width of a landscape photo and removes 1008 px at both the top and bottom; a portrait photo keeps under a fifth of its height. Landscape panoramas, textures and designed banners suit it best.
LinkedIn's advice for a blurry or pixelated cover is to choose an image with a larger file size, and it notes that photos look better than images with logos. The preset writes JPG at quality 0.92 or lossless PNG, both far below 8 MB at this size; blurriness usually comes from enlarging a small source, which the preset does when the source is narrower than 1584 px.
4:1
1584 × 396; four times as wide as tall.

Recommended size

Photos into 4:1 (computed from the code)
Example 12-megapixel sources; cover arithmetic from the resize task.
Landscape 4032 x 3024 -> crop 4032 x 1008 (1008 px off top and bottom)
33 % kept, scaled x 0.393 -> 1584 x 396
Portrait 3024 x 4032 -> crop 3024 x 756 (1638 px off top and bottom)
19 % kept, scaled x 0.524
Small source 1200 x 800 -> crop 1200 x 300, enlarged x 1.32
The last line is the typical cause of a blurry banner: a source narrower than 1584 px is enlarged, and LinkedIn then shows it large on wide screens.

Check the result
The result shows 1584×396 and the file is JPG or PNG.
View your profile at a narrow and a wide browser width: LinkedIn says the visible part changes.
If it looks soft, check the source width in the result line (at least 1584 px avoids enlargement).
Troubleshooting
Symptom

How to check
Fix
The banner looks blurry
A source narrower than 1584 px was enlarged
Source size in the result line
Use a wider original; LinkedIn also suggests an image with a larger file size
The subject is cut away
4:1 cover keeps only the central third of a 4:3 photo
LinkedIn's upload dialog also offers ready images to choose from.
What this page does not cover
LinkedIn publishes no safe area for the cover image; none is given here.

Frequently asked questions
What determines the supported size?
Actual device memory, storage and codec support. Tested examples are evidence, not a guarantee for every file.
Are my files uploaded?
This tool processes the files you open on your device without uploading them. Images you explicitly attach to community posts are uploaded separately. Optional engines and models are downloaded from third parties; those requests expose connection information such as your IP address.
Will my work be saved automatically?
No. Images and editing state stay in this tab; media output can use local temporary storage. Changing language preserves your work; reloading, closing the tab, or following a link to another page can clear it.
