    Limits and good practices

    Good practices

    • Keep the source JPG because PNG does not restore lost image detail.
    • Expect PNG files to be larger for photographs.
    • Check destination file-size limits.
    • Use PNG when lossless storage or exact pixels matter.

    Common mistakes

    Expecting better source quality
    PNG stops further JPEG loss but cannot restore details already removed by JPEG compression.
    Expecting a smaller file
    Photographs often become larger when encoded as PNG.

    FAQ

    Frequently asked questions

    Does JPG to PNG improve quality?

    It prevents additional JPEG loss in the new file, but it cannot restore details missing from the source.

    Will the PNG have transparency?

    No new transparency is created automatically because the JPG source has no alpha channel.

    Are the images uploaded?

    No. Conversion happens locally in the browser.
