About JPG to PNG Conversion

PNG format offers lossless compression and supports transparency, making it ideal for graphics, logos, and images requiring crisp edges. Unlike JPG, re-saving a PNG never introduces compression artifacts.

When to Convert JPG to PNG

  • You need transparent backgrounds for web design or Canva
  • You're working with logos, icons, or UI elements
  • You want to avoid quality loss from re-saving
  • You need screenshots with sharp, readable text

How It Works

Select your JPG files, preview them in step 2, then click Convert. The tool reads each image using the browser's built-in Canvas API and re-encodes it as PNG — entirely on your device. No data ever leaves your browser.

Frequently Asked Questions

Everything you need to know about the converter

How do I convert JPG to PNG?
Select your JPG files, review the preview in step 2, click "Convert to PNG", then download your files individually or as a ZIP archive.
Are my images uploaded to a server?
No. All processing happens inside your browser using the HTML5 Canvas API. Your images never leave your device — nothing is sent to any server.
Can I convert multiple files at once?
Yes. Select as many JPG files as you want. You can also add more files in the review step before converting. Download all at once as a ZIP archive.
Will image quality be maintained?
Yes. PNG uses lossless compression, so the converted file preserves every pixel from your original JPG exactly. No quality is lost in the conversion.
Does PNG support transparency?
PNG supports an alpha channel for transparency. However, since JPG images have no transparency data, the converted PNG will have a solid background — identical to the original JPG.
