What changes when a JPG becomes a PNG
JPG is a lossy format: when a photo is saved as JPG, small details are thrown away to make the file small. PNG is lossless: it records every pixel exactly. Converting from JPG to PNG therefore cannot bring lost detail back, but it does stop any further loss.
That is the main reason to do it. Every time a JPG is edited and saved again, a little more quality goes. Converting to PNG once, then editing the PNG, avoids that. PNG is also the format many design tools, icon makers and upload forms ask for.
Your browser decodes the JPG, turns it upright if the camera stored a rotation tag, and writes the pixels as PNG. Expect the PNG to be several times larger than the JPG. The EXIF data of the photo, including any GPS location, is not copied.
Questions about JPG to PNG
Does converting JPG to PNG improve quality?
No, and no converter can. The JPG has already lost some detail when it was saved. The PNG stores exactly what the JPG contains, without losing anything more, which makes it a good starting point for further editing.
Why is the PNG so much bigger than the JPG?
PNG compresses without loss, and photos have too much fine detail for that to shrink much. A 2 MB photo can easily become a 6 to 10 MB PNG. If size matters more than editing, keep the JPG or use WEBP.
Will the PNG have a transparent background?
No. A JPG has no transparency, so the PNG is fully opaque. You can remove a background afterwards in an image editor; the PNG format will keep it.
Can I convert several JPG files to PNG at once?
Yes. Add up to 50 images, press Convert, and each one becomes its own PNG file. Download them one at a time, or press "Download all (.zip)" to get one zip file. The zip is made in your browser too.
Does the converted image keep its EXIF data?
No. The new file contains only the picture: camera model, date, GPS location and other EXIF fields are not copied. Photos that were stored sideways with a rotation tag are turned upright first, so they still display the right way round.
Is it safe to convert JPG to PNG online?
With PlumPDF the images never leave your device. The conversion runs inside your browser tab, nothing is uploaded, and closing the tab discards everything. You can check by turning off your internet connection after the page loads and converting anyway.
