Questions & answers

01

Can converting to PNG restore lost JPG quality?

No, and no tool can. JPEG discards information while encoding, by quantising the frequency data of each 8x8 block, and that information is not stored anywhere in the file. PNG reproduces exactly the pixels it is given, so the conversion freezes the current state of the image instead of improving it.

02

Why is the PNG larger than the JPG?

PNG is lossless: it uses per-row prediction filters plus DEFLATE compression and has to reproduce every pixel exactly, including the compression noise JPEG introduced. That noise is close to random, and random data barely compresses, so a photo saved as PNG is routinely several times the size of its JPG.

03

When is JPG to PNG actually the right move?

When the image is about to be edited or annotated repeatedly. Every JPG save re-quantises the picture and compounds the artifacts of the previous one, so working in PNG between edits stops the loss from accumulating. It is also the answer when a tool or upload form simply refuses anything but PNG.

04

Is JPG to PNG free to use?

Yes, with no sign-up, no watermark and no file-size limit. The conversion runs on a canvas inside your browser, so your images never leave your device. Note that the canvas re-encode also drops EXIF metadata such as camera model and GPS coordinates.
