Free JPG to PNG Converter — Convert to Lossless Quality

JPG images use lossy compression, which can introduce artifacts, especially after repeated edits and re-saves. Our free JPG to PNG Converter transforms your JPG photos into the lossless PNG format, preserving every pixel exactly as it is — with batch processing and clear before/after size comparisons.

Why Use This Tool

  • Lossless quality: PNG preserves every pixel with zero compression artifacts.
  • Batch conversion: Convert multiple JPG files together.
  • Optional resize: Set a target width and/or height (with aspect ratio lock) before converting.
  • No upload required: Everything processes locally in your browser.
  • Ideal for editing: PNG avoids further quality loss during repeated edits.
