Social Media Image Resizer

1. Add a source image. A larger, sharp original gives you more room to crop. JPEG, PNG and WebP are supported.
2. Choose one or more presets. The first preset is the primary preview. Add others to create a set. Each preset is a convenience size, not a promise about how a platform will crop it in every layout.
3. Adjust the primary framing. Drag to move the image and use the zoom control. The same crop centre is applied to the other selected sizes, so you can keep the subject in the same relative position.
4. Choose crop or fit. Crop fills the frame and may cut the edges. Fit keeps the whole image and fills the remaining space with a background colour. Use crop for photos and fit for graphics with important edges.
5. Set the format and quality. JPEG is usually best for photos. PNG preserves transparency and sharp graphics. WebP can be smaller in modern browsers.
6. Generate and download. Check each result. The ZIP contains the selected sizes; individual downloads are better when you only need one platform.

A platform may show a square crop in one place and a tall crop in another. A link preview may be generated from the page rather than the image you upload. Profile banners are often covered by avatars or interface elements. The presets here give you a clean file at a common size; they cannot control the final layout. Keep important text and faces away from the edges, and check the current platform guidance before a campaign.

The bundled sizes are common values collected for convenience. Platforms change their recommended dimensions and crops. Treat every preset as a starting point and verify the current requirement in the platform’s own uploader or help centre. The interface does not claim that a file is “approved” or guaranteed to display without cropping. The notes on each preset point out the main risk, such as safe areas or a timeline crop.

• Preparing one photo for several social profiles without stretched faces.
• Making a consistent set of post images from a single design.
• Creating a link-preview image for a blog post.
• Producing a thumbnail and a vertical cover from the same source.
• Checking how a subject looks in square and vertical crops before publishing.

• No automatic face detection: you choose the crop. The tool does not know where the important part of the image is.
• No background removal: use the separate background tool if you need a cutout, and expect its plain-background limits.
• No batch input: one source image at a time, with multiple output sizes.
• No platform upload: the tool creates files; you still upload them yourself.
• No guarantee of display: a platform can crop, compress or reject a file for reasons outside this tool’s control.
