How to save JPG as PNG: what happens to quality and file size?

Coverton

A PNG copy gives you a file for subsequent editing without adding another round of JPEG compression during this conversion. It stores the pixels decoded from the JPG, including any compression damage already present in the source photo.

Illustration of this tool’s workflow; it is not a result from an uploaded file.

How to use this tool

  1. Choose files in JPG, JPEG format. Maximum files per batch: 100.
  2. Review Maximum width (px, 0 = original), Maximum height (px, 0 = original), then start processing.
  3. Download the PNG result and check its content and quality.

Choose the right settings

Leave both maximum dimensions at 0 to keep the source dimensions. Enter a width or height limit when you need a smaller copy, and the image keeps its aspect ratio within those limits.

Supported input
  • JPG, JPEG
Output
  • PNG
Available settings
  • Maximum width (px, 0 = original)
  • Maximum height (px, 0 = original)

Example input and output

photo.jpg → photo.png

Examples describe the workflow. Results depend on the source file and settings.

Check the result before you save

Compare lettering and edges at the same zoom level in both files. Check the resulting pixel dimensions and file size against the requirements of the place where you intend to use the image.

If the result is different from what you expected

Photographs can become larger when stored as PNG. This conversion cannot restore lost detail or create transparency in an opaque background, so those changes require a separate editing step.

Limits to keep in mind

  • PNG cannot restore detail already lost to JPEG compression, and photographs may become larger.
