What are JPG and PNG files?

JPG (Joint Photographic Experts Group, also written JPEG) has been the world's most popular photo format since 1992. It achieves small file sizes through lossy compression — an algorithm that analyses each image and discards fine detail the human eye barely perceives. A camera photo that would be 25 MB uncompressed becomes 2–4 MB as JPG with no visible quality difference. The trade-offs are that JPG does not support transparency, and every time a JPG is re-saved the compression runs again, slightly degrading the image each time.

PNG (Portable Network Graphics) was created in 1996 as an open, lossless alternative to GIF. PNG stores every pixel exactly as-is — no data is ever discarded — making it the ideal format for editing workflows, screenshots, graphics with text, logos, and anything where sharpness is critical. PNG also supports full alpha transparency, allowing images to have transparent or semi-transparent areas. The cost is file size: a photo saved as PNG will be several times larger than the same photo as JPG.

Convert JPG to PNG when you are starting a multi-step editing process and need to avoid cumulative quality loss from repeated saves. Also convert when you need to use a photo as a layer in a composite that requires a format with transparency support, or when downstream software requires PNG input specifically.

Frequently Asked Questions

No. Converting JPG to PNG won't restore detail that was already discarded by JPG compression. What PNG does is prevent any further quality loss — once your image is PNG, every subsequent edit or re-save is lossless. This makes JPG → PNG worthwhile when you're starting an editing workflow where multiple saves are involved.
Converting to PNG gives you a format that supports transparency, but the conversion itself won't remove the background — the converted PNG will have the same solid background as the original JPG. To make a background transparent, you'd need an image editor like Photoshop, GIMP, or an AI background-removal tool after converting.
No. Everything happens in your browser using the Canvas API — no data is sent to any server. You can disconnect from the internet after the page loads and conversion will still work.
JPG uses aggressive lossy compression that discards data to achieve small file sizes. PNG preserves every pixel using lossless compression, which results in larger files. A JPG photo that's 500 KB might become a 3–5 MB PNG. This is expected and correct — the PNG contains more data, not more visual quality.
Convert to PNG when you plan to edit the image multiple times — each JPG re-save adds compression artefacts, but PNG re-saves are lossless. Also convert to PNG if you need to use the image as a layer in a composite, or if downstream software requires PNG input. For final delivery or sharing, JPG is usually the better choice due to smaller file size.
