How it works
- Drop an image.
- Pick a platform and format — Instagram, YouTube, Twitter, LinkedIn, and more.
- The image is resized to that exact spec.
- Download the correctly-sized image.
What people use it for
- Sizing a post for Instagram, a YouTube thumbnail, or a LinkedIn banner.
- Getting the right dimensions without looking them up.
- Preparing one image for several platforms.
Good to know
- It resizes to the target dimensions; if the source ratio differs, plan for cropping or padding.
- Enlarging a small source to a large spec interpolates pixels and can look soft.
Frequently asked questions
Do I need to know the pixel sizes?
No — pick the platform and format and the correct dimensions are applied for you, so you don't have to look up each spec.
What if my image is the wrong shape?
Resizing to a different aspect ratio changes proportions; crop first (or accept padding) when the source shape doesn't match the target.
Is my image uploaded?
No. Resizing happens on a canvas in your browser.
