Free JPG to PNG converter

JPG is a compact photo format that uses lossy compression, which keeps file sizes small but can add artifacts around sharp edges and text.

PNG uses lossless compression and supports transparency, making it a better choice for logos, screenshots, interface graphics and images that will be edited again.

How to convert JPG to PNG

  1. Choose or drop your JPG file in the converter.
  2. Select PNG as the output format.
  3. Adjust quality or bitrate settings if they appear for this file type.
  4. Click Convert Now and keep the tab open until the download is ready.

Quality and file-size notes

  • A JPG cannot regain detail that was removed by earlier compression.
  • The PNG output may be larger because it stores image data losslessly.
  • Transparent backgrounds only appear if transparency exists or is added before conversion.

Limitations before you convert

  • Very large images can use significant browser memory.
  • Color profiles and metadata may not always be preserved by browser conversion.

File privacy

For supported conversions, Convertior processes files inside your browser. That design avoids unnecessary file uploads and is one reason the tool may feel faster for small files. Conversion engines, fonts or libraries may still be downloaded by the page so the tool can run.

Frequently asked questions

Is this JPG to PNG converter free?

Yes. The converter is free to use for common personal and everyday file conversion tasks.

Will conversion improve quality?

Changing format does not recreate missing detail. The best result comes from starting with the highest-quality original file you have.

Why did my conversion fail?

Failures usually happen because of unsupported codecs, damaged files, browser memory limits or very large files. Try a smaller file or a modern desktop browser.
