Resize image
Oversized photos are hard to email, slow down websites, and look wrong on social feeds. Resizing an image — scaling it down to fit a target width — is one of the fastest ways to make files more practical without sending them to a cloud service.

FAQ
How can I resize images without sending files to a server?
Add your images to this page, choose a resize preset or custom width, pick an output format, and click Convert. All processing runs locally in your browser — no files are sent to a server.
What do the email (800px) and social (1200px) presets do?
The email preset scales images to a maximum width of 800 pixels — a practical size for email attachments. The social preset uses 1200 pixels, which works well for many social media posts and profile headers.
Can I set a custom width?
Yes. Choose the Custom resize option and enter your own maximum width in pixels. The image is scaled proportionally so the width does not exceed your value.
Does resizing reduce file size?
Often yes. Fewer pixels usually means a smaller file, especially for photos. You can also lower quality or switch to JPG or WebP output for additional savings.
