About the Social Media Image Resizer
Every platform wants a different image size, and posting the wrong one gets your photo cropped, blurred or rejected. This tool resizes and crops any image to the exact, current dimensions for Instagram, YouTube, Facebook, X (Twitter), LinkedIn and Pinterest — in one click, right in your browser, so your photo is never uploaded.
Cover, Fit or Stretch
Choose Cover to fill the whole frame and crop the overflow (best for photos where edges do not matter), Fit to show the entire image on a padding colour of your choice (best for logos, graphics and screenshots you do not want cropped), or Stretch to fill the exact target size edge to edge, distorting the aspect ratio when needed. A live preview shows exactly what you will get before you download.
The sizes it covers
Presets include the Instagram square (1080×1080), portrait (1080×1350) and Story/Reel (1080×1920), YouTube thumbnail (1280×720) and channel art (2560×1440), Facebook post (1200×630) and cover, X post (1600×900) and header (1500×500), the LinkedIn post (1200×627), the Pinterest pin (1000×1500) and a square profile/DP (500×500).
Private and instant
Because the resize happens on a canvas in your browser, nothing is sent to a server — even large images stay on your device. Download the result as a PNG, JPG or WebP at high quality, ready to post. To shrink the final file size further, run it through the Image Compressor.
Frequently Asked Questions
What is the correct image size for Instagram?
A square post is 1080×1080, a portrait post is 1080×1350, and a Story or Reel is 1080×1920. Pick the matching preset and the tool crops or fits your image to it exactly.
What size should a YouTube thumbnail be?
YouTube thumbnails are 1280×720 (16:9). Select the YouTube thumbnail preset and download — the result meets the recommended size and ratio so it is never cropped or blurry.
Will resizing reduce my image quality?
Downsizing keeps images crisp. The tool uses high-quality scaling and a live preview so you can check the result. For a smaller file at the same size, save as JPG or compress it afterward.
Are my images uploaded to a server?
No. Everything is processed on a canvas in your browser, so your images are never uploaded, stored or seen by anyone — private even for large photos.
What is the difference between Cover, Fit and Stretch?
Cover fills the whole frame and crops the overflow (ideal for photos). Fit shows the entire image on a chosen background colour (ideal for logos and graphics). Stretch fills the exact target size edge to edge, distorting the aspect ratio — useful when the image must exactly match the dimensions.
