About

The format converter brings image and document conversions together in one place. Convert JPG to PNG, PNG to WEBP, combine several images into a single PDF, or turn the pages of a PDF into JPG/PNG/WEBP images. A quality slider is available for JPEG and WEBP output.

All conversions run entirely in your browser using Canvas and PDF technology; your files are never uploaded to any server. This keeps your data private and the results instant. The tool also converts text to UPPER/lowercase and title case, and prettifies messy JSON into a clean, readable layout.

How to use

  1. On the Image / PDF tab, drag in or select your files.
  2. Choose the target format (PNG, JPG, WEBP or PDF) and adjust quality if needed.
  3. Press Convert and download the result files.
