How to convert JPG to PNG?

The tool helps you change the image format of a compressed JPG to PNG (lossless compression format). Useful for further graphic editing or web use.

  1. Drag and drop files: Just drop the desired JPG images into the converter area.
  2. Processing:The browser re-encodes the image automatically.
  3. Download: Save the finished PNG files to disk.

How it works (Client-Side)

Most online services work through a server: you upload a file, the server processes it and sends it back. We use WebAssembly to move the processing to the client side.

  • Speed: You skip the “Upload to the server” and “Download from the server” stages. Conversion occurs instantly using your processor.
  • Privacy: Files never physically leave your device. There are no network requests to send images as a class.
  • No limits: Since you are using the resources of your computer, it makes no sense for us to limit the number of files or their size.

Frequently asked questions

What is the difference between JPG and PNG?

JPG uses lossy compression (good for photos, bad for text/graphics). PNG compresses without loss of quality, which is better for drawings, logos, and graphics with clear edges.

Is it free?

Yes. The service is completely free and does not require registration.

Is it safe to upload documents?

Yes, since there is no “uploading” to the Internet. The entire process takes place inside your browser's RAM. Nobody will see your files.
