Overview

Convert and compress images between PNG, JPG, and WebP right in the browser. Files are processed locally without uploading to a server, so your data stays private. It is useful for converting to WebP for web optimization or to JPG/PNG for compatibility.

Key Features

  • Convert between PNG, JPG, and WebP formats
  • Quality (compression) slider control
  • Before/after file size comparison
  • All processing done in-browser (no server upload)
  • Instant download of converted images

How to Use

  1. Upload an image by drag-and-drop or file selection.
  2. Choose the output format: PNG, JPG, or WebP.
  3. Adjust the compression level with the quality slider.
  4. Click convert and download the result.

Tips

  • For website images, WebP offers the smallest file size at the same visual quality.
  • PNG is best for logos and icons that need transparency; JPG is best for photos.
  • Around 80% quality is visually indistinguishable from the original while significantly reducing file size.

FAQ

Are my images uploaded to a server?
No. All conversions are processed locally using the browser's Canvas API. Your image data is never sent to any external server.
Why does the file get larger when converting to PNG?
PNG uses lossless compression, so files tend to be larger than lossy formats like JPG or WebP. The trade-off is zero quality loss.
Can I convert multiple images at once?
Currently only one image can be converted at a time. To convert multiple images, repeat the process for each file.
