Resize photo for web when full-resolution camera files slow your site. Scale to display width, then compress for faster LCP and lower bandwidth.
Match image width to CSS max-width—oversized assets are the top cause of slow LCP.
Use 2× sizes only for retina hero images, not every inline photo.

How to use this tool
Upload the photo, set width to your layout max (often 1200–1600 px), download, then compress if still large.

- Banner 2400×800 → 1200×400 for faster email newsletter load times.

How it works
Upload a JPG, PNG, WebP, or GIF image, choose new dimensions or a scale percentage, and download the resized file. Aspect ratio can be locked, and you can keep the original format or export as JPG, PNG, or WebP. Resizing runs entirely in your browser—files are not uploaded to a server.
Limitations
Upscaling cannot recover detail that was not in the original image. Extreme aspect-ratio changes may crop or distort if not constrained.
Privacy and file handling
