The Next-Gen Image Converter turns your JPG, PNG and GIF images into modern WebP and AVIF formats directly in your browser — no uploads, no server, no waiting in a queue. Drag in multiple images at once, pick a quality level and an optional maximum width, and instantly compare the original size against the WebP and AVIF versions, with the percentage saved shown for every file. Images are usually the heaviest part of a web page, and converting a photo library to WebP typically cuts its weight by 25 to 40 percent, while AVIF often saves more than half.
This free tool by Hosting Cambodia exists because image weight is the single biggest lever for page speed and Core Web Vitals: a lighter hero image directly improves Largest Contentful Paint, the metric Google uses to judge loading performance. Because everything runs on your own device using the browser's built-in encoders, your photos never leave your computer — ideal for product shots, client work, or anything private. Convert, download individually or all at once, and upload the smaller files to your WordPress media library or any website.
Frequently asked questions
Are my images uploaded to a server?
No. The converter uses your browser's own canvas encoders, so every image is read, resized and re-encoded entirely on your device. Nothing is transmitted anywhere, which also makes it fast and safe for private or client images.
Why is AVIF unavailable in my browser?
AVIF encoding is currently built into Chromium-based browsers like Chrome and Edge, while Safari and Firefox can display AVIF but not create it. The tool detects this automatically and still gives you WebP, which every modern browser supports.
What quality setting should I use for web images?
80 percent is the sweet spot for photographs — the savings are large and the difference is invisible at normal viewing sizes. For screenshots or graphics with text, try 90 percent, and use the max-width resize so you never ship pixels larger than your layout displays.
