What is the Image Converter?

The Image Converter lets you convert images between PNG, JPEG, and WebP formats. All processing happens entirely in your browser using the Canvas API — your image data is never sent to a server.

WebP typically produces smaller files than PNG or JPEG at similar visual quality, which helps improve page load times. PNG, on the other hand, supports transparency (an alpha channel), making it the right choice when you need a transparent background.

Use Cases

  • Convert website images to WebP to improve page load speed
  • Convert a JPEG photo to PNG when you need transparency support
  • Convert an image exported from a design tool to a different format

How to Use

  1. Select an image file, or drag and drop it into the drop zone.
  2. Choose the target format (PNG, JPEG, or WebP).
  3. For JPEG and WebP, adjust the quality slider if needed.
  4. Click "Convert" to preview the result.
  5. Click "Download" to save the converted image.
