About JPG to PNG
JPEG and PNG solve different problems. JPEG uses lossy compression tuned for photographs: it achieves small files by discarding subtle detail, and it cannot store transparency. PNG is lossless — every pixel is reproduced exactly — and it has a full alpha channel.
Converting JPG to PNG is worthwhile when a file is going into an editing pipeline, when a tool or platform specifically requires PNG, or when you are about to add a transparent background. Because PNG is lossless, no further quality is lost from the point of conversion onward.
One honest caveat: converting cannot restore detail that JPEG already discarded. The compression artefacts baked into the source are copied faithfully into the PNG. What you gain is a file that will not degrade further with each subsequent save.
How to convert JPG to PNG
Add your JPG files
Drag and drop, or tap Select Images. Up to 30 files can be converted in one batch.
Convert
Press Convert. Each image is decoded and re-encoded as PNG on your device.
Download
Save files individually, or use Download all to get the whole batch.
When PNG is the right choice
- The image needs a transparent background — logos, icons, stickers and overlays.
- The file will be edited and re-saved several times, and you want no cumulative quality loss.
- The image is a screenshot, diagram, chart or anything with sharp edges and flat colour, where JPEG produces visible fringing.
- A platform or piece of software explicitly requires PNG input.
Expect a bigger file
PNG stores every pixel exactly, so photographic images almost always grow when converted — a 1 MB JPEG commonly becomes a 4–8 MB PNG. That is the cost of being lossless, not a fault in the conversion.
If your goal is a smaller file rather than a lossless one, WebP is usually the better destination: it supports transparency like PNG but compresses photographs close to JPEG efficiency.
