How to Use the Social Media Image Resizer Online
Pick a platform and a slot, and this resizes your picture to the exact pixels it wants. The list covers Instagram posts, stories and reels, YouTube thumbnails and banners, Facebook covers, LinkedIn headers, X timeline images and Pinterest pins, each with its width and height. You choose whether the picture fills the frame and is cropped, or fits inside it with a background colour.
Resizes to the exact dimensions any platform wants. Every platform crops differently on different surfaces, so an image that looks right in a feed can be cut through the middle as a thumbnail — sizing deliberately beats letting the platform decide.
No software to install Free Works on any device

Tips and Good to Know
-
Fill mode crops from the centre. If the subject is near an edge, crop the picture roughly to shape with Crop Image first so the important part survives.

Presets are the platforms' published sizes; they change from time to time, so check the platform's own help page for anything unusual.
-
For a YouTube thumbnail alone, YouTube Thumbnail Resizer opens with just that platform's sizes and nothing else to scroll past.
Frequently Asked Questions
Answers to common questions about this tool.
Do I need to install anything to use the Social Media Image Resizer?
No. Social Media Image Resizer runs entirely in your browser — there is nothing to download, no extension and no desktop program. It works the same on Windows, macOS, Linux, Android and iPhone.
Is it safe to use the Social Media Image Resizer online?
Safer than the usual alternative, yes. Most online tools upload your file to a server you know nothing about, where it sits until someone deletes it. Here the file never leaves your device — the processing happens in the page itself, so there is no server copy to leak, retain or sell.
Does Social Media Image Resizer reduce my photo’s quality?
Converting and cropping keep quality close to the original. Compressing trades a little detail for a much smaller file, and a lighter setting keeps more of it. Compare the preview with your original before saving.
Will my photo be accepted by the exam form?
The exam photo tools follow the size, dimensions and file weight given in the official notice. Always read the latest notice too, because boards sometimes change their rules between years.
Can I edit pictures with Social Media Image Resizer straight from my gallery?
Yes. Pick a photo from your gallery or take one with the camera, then save the result back to your phone. Everything works in the browser, so there is no app to install.
Is Social Media Image Resizer free with no watermark?
Yes. Use it for as many pictures as you need without an account, and each image comes back without any logo or mark from the site.
