Convert PNG, JPG, and WebP images to each other in the browser.

Category: Image Tools

When to use?

Use it when a service requires a different image format, or to convert WebP to JPG/PNG.

How to use

  • Select an image.
  • Pick the output format.
  • For JPG or WebP, adjust quality, then download the converted file.

Input Explanation

Select the source images, then choose the target format (JPG, PNG, WebP). JPG and WebP use a 1–100 quality value; PNG does not.

Calculation Basis

It decodes the image in browser memory, then re-encodes it to the selected new image format.

Usage Examples

  • Match file format - Convert to the needed format among PNG, JPG, WebP.
  • Prepare images for upload - Preview the result, then tidy images for blogs, shops, or social media.
  • Compare results - Check original and result side by side for quality and size.

Examples

  • Convert a transparent PNG to WebP → keep transparency while optimizing size
  • Convert a WebP photo to JPG → upload to services without WebP support

Cautions

  • Converting from PNG/WebP to JPG fills transparent areas with white.
  • Extremely high-resolution large files may fail to convert due to browser image-decoding limits.

FAQ

Is the transparent background kept?

PNG and WebP support transparency, but converting to JPG can remove it.

Are images sent to a server?

No. Format conversion runs on browser Canvas, so images are not uploaded.

Does converting change quality?

PNG is lossless; JPG/WebP are lossy, so converting to JPG can slightly reduce quality.

Are HEIC or GIF converted?

Only formats the browser can decode are accepted (HEIC may be unsupported), and results are saved as still images.
