Social Media Image Resizer
Crop and scale any image to the exact dimensions each network expects — posts, stories, thumbnails, and covers — all resized privately in your browser.
The Social Media Image Resizer crops and scales an image to the precise size each platform expects.
Everything runs in your browser, so your image is never uploaded.
How to resize for social
- Upload an image.
- Pick a preset and a fit mode (cover or contain).
- Download at the exact platform size.
Cover or contain
Cover fills the frame and crops the edges — ideal when the subject is centered. Contain fits the whole image and pads the sides with a color you choose.
For a general resize to custom dimensions instead of presets, the Image Resizer handles any size.

Frequently Asked Questions
Is my image uploaded?
No. The resize and crop happen in your browser, so your image stays on your device.
What is the difference between cover and contain?
Cover fills the frame and crops the overflow so there are no borders. Contain fits the whole image inside and pads the empty space with a background color.
Which sizes are included?
Presets for Instagram post/portrait/story, Facebook post/cover, X post/header, YouTube thumbnail/channel art, LinkedIn post/cover, Pinterest Pin, and TikTok.
Will the output be the exact pixel size?
Yes. The image is exported at the exact dimensions of the preset you choose, ready to upload.
