Lynx Image Resizer

Resize images instantly in your browser — no uploads, no file size limits, no watermarks. Drop your image, set the target dimensions (or pick a preset like 50% or 200%), and download the resized file. Great for preparing social media images, email attachments, website graphics, or shrinking oversized photos before sharing. The Lynx Image Resizer runs entirely client-side using the Canvas API, so your files never leave your device.

How does the image resizer work?

The resizer uses the HTML5 Canvas API built into your browser. When you drop or select an image, it loads into memory locally. You set your desired dimensions, and the tool redraws the image onto a canvas at the new size, then exports it as a downloadable file. The entire process happens on your device — nothing is uploaded.

Will resizing reduce image quality?

Scaling down generally preserves quality well. Scaling up beyond the original dimensions can introduce blur since the browser has to interpolate new pixels. For best results when enlarging, keep it under 200% of the original size. You can also control output quality with the quality slider when saving as JPG or WebP.

What output formats can I save as?

You can save the resized image in its original format, or convert it to JPG, PNG, or WebP during the resize. JPG is best for photos (smaller files, lossy). PNG preserves transparency (lossless). WebP gives the best compression of all three and is supported by every modern browser.

Is there a file size or dimension limit?

There are no artificial limits. Since everything runs in your browser, the only constraint is your device's available memory. Most modern devices can handle images up to 10,000 x 10,000 pixels without issues. Very large images (50+ megapixels) may be slow on older devices.
