JPG to PNG: convert images without losing quality
Converting JPG to PNG stops further quality loss and produces a file you can edit, layer and re-save safely. Here is when that trade-off is worth the larger size.
What changes when a JPG becomes a PNG
JPEG is a lossy format. It stores an approximation of the picture and discards detail the eye is unlikely to notice, which is why the files stay small and why every re-save removes a little more information.
PNG stores every pixel exactly, so once the conversion is done, editing and re-saving no longer degrades the image. Transparency, which JPEG cannot represent at all, also becomes available.
Does converting to PNG recover lost quality?
No. Detail removed by the original JPEG compression cannot be restored. The PNG preserves what remains, pixel for pixel.
What you gain is stability. A lossless working file survives cropping, retouching and repeated exports without collecting new compression artefacts along the way.
The file size trade-off
PNG files are noticeably larger, often two to three times the size of the original JPEG, because no pixels are thrown away to save space.
That is a sensible cost for an image you plan to edit, but wasteful for a photo that only needs to be displayed. For web delivery, WEBP usually offers a better balance between size and quality.
When PNG is the right choice
Choose PNG when the image needs a transparent background, when it contains text or sharp interface graphics, or when it will be edited more than once.
Stay with JPEG when the photograph is finished, needs no transparency, and must remain as small as possible.
The conversion runs entirely in your browser, so the image is never uploaded.Open the JPG to PNG converter
