How do I resize an image for social media?

Drop your photo onto the upload zone (or click to browse, or paste with Ctrl+V / Cmd+V), pick a platform size preset, choose Cover (crop) or Contain (pad), and the preview shows the exact result. Press Export, choose JPEG, PNG, or WebP, and download. It is completely free and runs entirely in your browser, so your image is never uploaded.

Are images uploaded to a server?

No. All processing runs entirely in your browser; images never leave your device. This is the core design principle of the tool.

Which sizes are included?

Instagram Post (1080×1080), Portrait (1080×1350) and Story/Reel (1080×1920); YouTube Thumbnail (1280×720); X/Twitter Post (1600×900) and Header (1500×500); Facebook Cover (820×312); LinkedIn Banner (1584×396); Pinterest Pin (1000×1500); and a square Profile Picture (400×400).

What is the difference between Cover and Contain?

Cover scales the image to fill the whole frame and crops the overflow (no empty space, but edges may be cut). Contain scales the whole image to fit inside the frame and pads the leftover space with a colour you choose (nothing is cropped).

Is the Social Media Image Resizer free?

Yes — resizing photos to exact Instagram, YouTube, X, Facebook, LinkedIn, and Pinterest dimensions is completely free, forever. No account, no sign-up, and no limit on how many images you resize. All processing uses the Canvas API in your browser; your images are never sent to any server. The site is ad-supported.

Does it work offline?

Yes. The tool uses the Canvas API and needs no server connection. Disconnect after loading the page and it still works.

What image formats are supported?

Input: JPEG, PNG, WebP, AVIF (browser-decoded). Output: JPEG, PNG, WebP.

Instagram feed posts are 1080 pixels wide; square is 1080×1080 and the tallest supported portrait is 1080×1350 (4:5).
A YouTube thumbnail is 1280×720 (16:9) with a recommended minimum width of 640 pixels.
Cropping (cover) versus padding (contain) is the key choice: cover guarantees the frame is filled, contain guarantees nothing is cut off.
Resampling uses the Canvas API with high-quality image smoothing, specified by the W3C HTML Living Standard and supported in all modern browsers.
Because resizing is client-side, the image is never transmitted, so unpublished content stays private until you post it.
