About Image Converter
Image Converter changes image files from one format to another, many at a time. Turn heavy PNGs into lightweight WebP for your website, convert WebP downloads into JPG that every app can open, or trace a logo into a real SVG vector.
How it works
Each image is decoded by your browser and redrawn on a canvas, optionally resized to the maximum width you set. It's then re-encoded in the target format at the quality you choose. Because your browser does the encoding, conversion is fast and works offline once the page has loaded. When you're done, download each file separately or everything as a single ZIP.
For SVG there are two modes. Vector trace analyzes the image and rebuilds it from colored shapes and paths, giving a true vector that scales infinitely. Embed image wraps the original pixels inside an SVG file, which is useful when a tool requires SVG but your image is a photo.
Which format should you choose?
- WebP: the best choice for websites. It's usually 25–35% smaller than JPG at the same quality and supports transparency.
- JPG: photos that need to open everywhere, including email, older software and printers.
- PNG: lossless, ideal for screenshots, graphics with text and anything that needs transparency.
- SVG: logos, icons and flat illustrations that must stay sharp at any size.
Tips for the best results
- A quality of 75–85 is the sweet spot for WebP and JPG: much smaller files with no visible difference.
- Set a maximum width, such as 1600 px, for web images. Resizing saves more space than any format change.
- When converting transparent images to JPG, choose the background color that will fill the transparent areas.
- Vector tracing works best on images with few, flat colors. For photos, use embed mode instead.
