What you should know
JPEG to PNG converts a compressed photograph into a lossless format. It is useful to continue graphic work — cutouts, compositing, retouching — without adding degradation at every save.
Beware of the misunderstanding: conversion does not restore quality lost when the JPEG was shot. It simply freezes the current state in a format that will add no more errors.
Strengths
- Stops degradation during successive edits
- Enables clean transparency and cutouts
- Stable working format for graphic design
- No further loss after conversion
Limitations to know
- The file becomes several times heavier
- Original quality is not recovered
- Pointless if the image is neither retouched nor composited
- Unsuitable for quick sending or a light website
When to use it
Convert to PNG as soon as you need to cut out, composite or retouch a photo, or add transparency. If you simply want to send or publish it, keep the JPEG.
Quality, size and compatibility
Quality stays that of the original JPEG: conversion adds and removes nothing. PNG becomes the new starting point for edits, with no extra generation loss at each save.
Frequently asked questions
- Does JPEG to PNG improve quality?
- No. Details removed by JPEG are permanently lost. PNG only prevents losing more during subsequent edits.
- Why is the PNG file so heavy?
- Because it describes every pixel without lossy compression. For a photograph, expect three to five times the original JPEG size.
