What is Image Converter & Compressor?
Images are usually the heaviest thing on a web page, and format choice makes an enormous difference. WebP is typically 25 to 35% smaller than JPG at equivalent quality, and every modern browser supports it. Converting to WebP is one of the easiest page-speed wins available.
This tool uses the browser's Canvas API to decode and re-encode your image. Your file is never uploaded anywhere — worth noting, since images often carry private content and many online compression services retain what you upload.
How to use
- Drop an image onto the box, or click to choose a file.
- Pick a target format. WebP gives the smallest files, JPG the broadest compatibility, PNG preserves transparency.
- Drag the quality slider to balance size against sharpness. Around 80 to 85% is usually the sweet spot.
- Check the size reduction, then click Download.
Frequently asked questions
Is my image uploaded to a server?
No. Everything runs through the Canvas API in your browser. You can verify it by disconnecting from the internet after the page loads — conversion still works.
Why does converting to PNG make the file bigger?
PNG uses lossless compression, which suits flat-colour images like logos and screenshots. For detailed photographs, PNG is always substantially larger than JPG or WebP. Choose PNG only when you need transparency.
What happens to transparent PNGs converted to JPG?
JPG has no alpha channel, so the tool fills the background with white first. Without that, transparent areas would turn black. To keep transparency and still save space, choose WebP.
