JPG to PNG

A JPG to PNG converter re-encodes a JPEG photo into the PNG format, which uses lossless compression and supports transparency. This tool does it directly in your browser with no upload, and it can batch-process several files in one session. The important thing to understand is what the conversion can and cannot do for quality. PNG is lossless, so once your image is in PNG form no further compression artifacts will be added by editing or re-saving it. That is exactly why designers convert to PNG before doing repeated edits in a tool like Figma or Photoshop, where a JPG would accumulate visible artifacts with every save. However, converting cannot undo damage that is already baked into the source. If the original JPG was saved at low quality, the blocky compression artifacts and color banding are part of its pixels, and the PNG faithfully preserves those flaws rather than removing them. Converting a bad JPG to PNG gives you a lossless copy of a flawed image, not a restored one. Expect the file to get larger, often substantially. PNG stores photographic detail less efficiently than JPG's perceptual compression, so a photo that was a 400 KB JPG might become a multi-megabyte PNG. That trade is worth it when you need an edit-safe master or crisp screenshot text, but not when you simply want a smaller file. One more clarification: converting a JPG does not add transparency. A JPG has no alpha channel, so the resulting PNG is fully opaque; to actually cut out a background you would run a background remover on the PNG afterward. Everything runs locally, so your images stay private, and the converter is well suited to preparing screenshots, design assets, and archival copies where avoiding further lossy compression matters.
