What is a social media image cropper?
A social media image cropper is a tool that trims a photo to the exact width, height and aspect ratio a platform expects, so it is not cropped unpredictably after upload. Every network uses different shapes: a round profile photo, a tall story, a very wide banner. Upload a photo that does not match and the platform decides what to cut, often a forehead, a logo or the last word of your tagline.
This cropper has seven presets for the images people change most: Instagram profile picture, Instagram post, Instagram portrait post (4:5), Instagram story, YouTube banner, X header and LinkedIn banner. It shows the circle crop for profile photos and the mobile safe area for YouTube banners, so you can see what viewers will actually see.
How to crop an image for Instagram and other platforms
- Add an image. Drop it on the box or tap to choose. JPG, PNG and WebP work; iPhone HEIC photos work once your phone or browser converts them, which most do when you pick from the gallery.
- Pick a target size under Target size: Instagram profile (320 x 320), Instagram post (1080 x 1080), Instagram portrait post (1080 x 1350), Instagram story (1080 x 1920), YouTube banner (2560 x 1440), X header (1500 x 500) or LinkedIn banner (1584 x 396). The size label appears on the preview.
- Frame it. Drag the image to move it and use the Zoom slider (1x to 4x) or your mouse wheel. The image always fills the frame, so there are no empty edges.
- Use the guides. The Instagram profile preset shows a circle, because profile photos are displayed round. The YouTube banner preset shows a dashed box for the area visible on phones.
- Download PNG or JPG. The file is exported at the full target size even though the preview is smaller, and named like
yt-banner-2560x1440.jpg. JPG exports use 92% quality on a white background.
Switching to another preset resets the zoom and position, so you can crop the same photo for every platform one after another.
Social media image sizes cheat sheet
Recommended sizes at the time of writing. Platforms update layouts, so check after a major app redesign.
| Image | Size in this tool | Shape | What to know |
|---|---|---|---|
| Instagram profile picture | 320 x 320 px | 1:1, shown as a circle | Displays at about 110 px on phones; corners are cut off |
| Instagram post | 1080 x 1080 px | 1:1 | Square; the profile grid shows posts as 3:4 previews |
| Instagram portrait post | 1080 x 1350 px | 4:5 | Takes up the most room in the feed; Instagram also accepts 3:4 |
| Instagram story / Reel cover | 1080 x 1920 px | 9:16 | Keep text away from the top and bottom, where profile info and reply bar sit |
| YouTube channel banner | 2560 x 1440 px | 16:9 | Safe area 1546 x 423 px in the centre; minimum upload 2048 x 1152; file up to 6 MB |
| X (Twitter) header | 1500 x 500 px | 3:1 | Your profile photo overlaps the lower left |
| LinkedIn personal banner | 1584 x 396 px | 4:1 | Your profile photo covers part of the left side, more on mobile |

Examples: one photo, every profile
- Freelancer refreshing their brand: crop one headshot to 320 x 320 for Instagram, then a wide office or workspace shot to the LinkedIn banner and X header so all profiles match.
- YouTuber launching a channel: place the channel name and upload schedule inside the dashed safe area so it shows on phones, and let scenery fill the rest for TVs.
- Small shop in Jaipur: crop a product flat-lay to a square post and a 9:16 story announcing the sale.
- Musician: crop the album cover to a square post and the band photo to a story with room for a link sticker.
- Job seeker: a clean 320 x 320 profile photo with the face centred inside the circle, plus a simple LinkedIn banner.
Tips for profile pictures, banners and stories
Tips
- Profile pictures: fill most of the circle with your face or logo. At about 110 px on screen, a full-body shot becomes a speck.
- Start with a large photo. The cropper exports at full target size, so a small source gets stretched and looks soft. For a YouTube banner, start with a photo at least 2560 px wide.
- Banners: keep text in the middle. Profile photos and buttons cover the edges on X and LinkedIn.
- Logos with transparency: export PNG to keep transparent pixels; JPG fills them with white.
Mistakes to avoid
- Placing a logo in the corner of a profile photo, where the circle crop removes it.
- Putting the channel name at the edge of a YouTube banner; phones only show the centre strip.
- Zooming far into a small photo, which multiplies blur.
- Cropping a screenshot of a photo instead of the original file.
Cropper vs cropping inside the app or a photo editor
Cropping inside Instagram, YouTube or LinkedIn works for quick changes, but the in-app editors vary, rarely show safe areas, and some compress the result. Phone photo editors crop to a ratio, not exact pixels, so you still guess the final size. Full editors such as Photoshop or Canva give total control, which is worth it when you are adding text and graphics. This cropper sits in between: exact presets, platform guides and a file ready to upload in a few seconds, with no account.
Is my photo uploaded when I crop it?
No. The image is opened, cropped and exported inside your browser using the canvas. Nothing is sent to a server. Re-drawing on a canvas also leaves out the original file's EXIF metadata, such as camera details and GPS location, in the exported image. If you want to blur faces or details before sharing, use blur image.
Use the same photo on your link in bio page
The 320 x 320 crop you made for Instagram also works as the avatar on a Biolinko page, which keeps your profile and your link page recognisably yours. Your page at biolinko.me/yourname can then collect your YouTube, LinkedIn and shop links in one place. See link in bio for YouTube or create your free page.
