Social media preset
Shape
Circle output is intended for profile picture presets. For PNG, WebP, AVIF, BMP and TIFF, the corners outside the circle are transparent. For JPEG, JFIF and HEIC, those corners are filled with white because those formats do not preserve transparency in this tool.
Output format
85%
This tool resizes directly to the selected pixel size. If your source image does not already match the preset aspect ratio, the result can look stretched. For the cleanest result, first crop the image to the desired ratio in the Crop tool, then use this Social Media Resizer.

The supplied 1080 × 1350 PNG has a taller aspect ratio for an Instagram portrait post.
Aspect-ratio note: This tool resizes directly to a preset size. When the source and target ratios differ, the resulting artwork can look stretched, including the lettering and coffee cup. For a non-stretched export, first prepare a matching composition using the Crop Image tool, then resize it.

Prepare images for common social-media sizes
Social platforms use different aspect ratios for profile pictures, posts, stories, thumbnails, covers and other visual placements. Starting from a platform preset is faster than looking up dimensions every time and helps you keep important content inside the visible area.
The Social Media Resizer provides ready-made sizes for platforms such as Instagram, Facebook, LinkedIn, YouTube, X and TikTok. You can position the source image, prepare the required output and create circular profile-picture output where that shape is useful, all without sending the photo to a remote processing service.
How it works
2
Fit the composition
Adjust how the image fills the target size and keep faces, logos and text inside the important area.
3
Export the social image
Create the prepared image locally and download the version ready for posting or upload.
Tips for social-media images
- Keep important text and faces away from the extreme edges because apps may display previews with additional cropping.
- Use a high-quality source image so the final platform-sized export remains sharp.
- For profile photos, preview how the subject looks inside a circular crop before publishing.
- If file size is still too large after resizing, run the result through Compress Image before uploading it.
Frequently asked questions
Why do social networks need different image sizes?
Different placements use different layouts and aspect ratios. A profile photo, feed post, story and video thumbnail are displayed in different containers.
Will the platform crop my image again?
It can. Interfaces and previews sometimes use their own crop, so keep important content away from edges and check the platform preview before publishing.
Can I create a circular profile image?
The tool includes circular profile-picture output for workflows where a round image or transparent circular result is useful.
Should I resize before or after adding a watermark?
Either can work, but resizing first makes it easier to judge watermark size and placement on the final canvas.
Are my social images uploaded to Image Toolroom?
No upload is required for the normal resizing workflow. The image is processed locally in your browser.
