What is Image Conversion?
Image conversion is the process of changing an image from one file format to another — for example, converting a PNG to WEBP or a JPG to AVIF. Different formats use different compression algorithms, which can dramatically affect file size, quality, and browser compatibility.
Our tool performs all conversion directly in your browser using the HTML5 Canvas API. Your images are never uploaded to a server — ensuring complete privacy and instant processing with no file size restrictions per image.
Supported Formats
WEBP
Best overall: 30% smaller than JPG with similar quality.
AVIF
Next-gen: up to 50% smaller, perfect for modern browsers.
JPG
Universal compatibility, ideal for photos.
PNG
Lossless quality, best for logos and graphics with transparency.
Why Optimize Your Images?
- 1
Faster Page Loads
Images account for up to 75% of a webpage's total data. Converting to WEBP or AVIF can cut that dramatically, improving Time to Interactive (TTI).
- 2
Better Core Web Vitals
Google's ranking algorithm uses Largest Contentful Paint (LCP) as a key signal. Optimized images directly improve your LCP score.
- 3
Lower Bandwidth Costs
Smaller images mean less data transferred — saving money for sites with high traffic or users on metered connections.
- 4
Improved Mobile UX
Mobile users on slower networks benefit the most from optimized images. A 2MB PNG converted to a 200KB WEBP loads 10x faster.
- 5
Bulk Processing
Process up to 5 images at once in the free plan. Each image is independently optimized and can be downloaded separately or as a ZIP archive.
