Social Media Image Resizer
One image, every platform size. Pick a preset — YouTube thumbnail 1280 × 720, Instagram story 1080 × 1920, LinkedIn banner 1584 × 396, X header 1500 × 500, Pinterest pin 1000 × 1500, Open Graph 1200 × 630 — and the tool crops or pads your image to fit exactly. Choose crop-to-fill for a full-bleed result or fit-with-padding to keep the whole image visible on a background colour you pick.

Frequently Asked Questions
- What size is a YouTube thumbnail?
- 1280 × 720 px, 16:9, under 2 MB. Select the YouTube Thumbnail preset and the tool exports exactly that.
- What size should a LinkedIn post image be?
- 1200 × 627 px for a link-style post image and 1080 × 1350 px for a portrait carousel page. Both are in the preset list.
- Crop to fill or fit with padding?
- Crop to fill looks better in feeds because there are no bars, but it trims the edges. Use fit with padding when the whole image matters, such as a chart or a full-body product shot.
