How to Convert Images Between PNG, JPG, WebP and SVG
Learn the strengths of each image format and how to convert between them for the right use case.
An image format converter changes a PNG to JPG, JPG to WebP, WebP to JPG, or SVG to PNG directly in the browser. Choosing the right format for each image improves quality and load time.
When to use each format
- PNG — lossless, supports transparency; best for logos, icons, and sharp graphics.
- JPG — lossy, no transparency; best for photographs and complex images.
- WebP — modern, supports both lossy and lossless plus transparency; best for the web where supported.
- SVG — vector, scales without pixelation; best for logos and simple illustrations.
How conversion works
The converter decodes the source image into pixels in the browser, then re-encodes those pixels in the target format. Converting from a lossy format (JPG) to a lossless one (PNG) does not recover lost quality — it just preserves the current pixels. Converting a photo to SVG is not meaningful because SVG is for vector graphics, not photographs.
How to convert an image
- Upload the source image.
- Choose the target format.
- Convert and download the result.
Examples
A PNG logo with transparency stays crisp when kept as PNG or converted to WebP; converting it to JPG would replace transparency with a solid background. A JPG photo converted to WebP shrinks with little quality loss. An SVG icon converted to PNG gives a fixed-size raster for contexts that cannot use SVG.
When an image format converter is useful
- Switching to WebP for faster web images.
- Producing a PNG from an SVG for compatibility.
- Creating a JPG thumbnail from a PNG screenshot.
- Preparing images for platforms that require a specific format.
