Resize Image for Social Media Free

Frequently asked questions

How do I resize an image for social media?

Upload your image. Choose one of the six presets (e.g. IG Post, IG Story, Twitter, YouTube Thumbnail, Facebook Cover, LinkedIn). Optionally pick a background color. Click Resize and download the JPG.

Are my images sent to a server?

No. Resizing is done with the Canvas API in your browser. Your image never leaves your device.

What is the background color for?

When your image does not match the preset aspect ratio, the tool fills the remaining space with a solid color. Default is white; you can change it with the color picker.

Why is the output always JPG?

JPG at 92% quality is a good balance for social posts and keeps file size small. For PNG (e.g. transparency) use the main Resize Image tool.

Does it work on mobile?

Yes. Open the tool in your mobile browser, upload an image, pick a preset and optional background color, then resize and download.

Can I use custom dimensions?

This tool only offers the six social presets. For custom dimensions use the main Resize Image tool on FileFlip.

Will quality be reduced?

The image is scaled to fit the preset. If larger than the preset it is downscaled (quality usually good). If smaller it is upscaled and may look softer.

What are the exact preset sizes?

IG Post 1080×1080; IG Story / TikTok 1080×1920; Twitter 1200×675; YouTube Thumbnail 1280×720; Facebook Cover 820×312; LinkedIn Post 1200×627. All in pixels.

Is there a file size limit?

There is no fixed limit. Very large images may take a few seconds to process.

Does it work in all browsers?

Yes. Any modern browser that supports the Canvas API can run this tool.
