Convert PNG to JPG

Instant, local, and much smaller on the other side — PNG photographs are usually several times larger than they need to be.

Every byte of that work happened on your own machine. Verify it: open DevTools → Network, and use the tool. No request carries your image, because none is made.

Why the file shrinks so dramatically

PNG is lossless: it stores enough information to reconstruct every pixel exactly. That is the right trade for a logo, a screenshot or a diagram, where flat areas of colour compress beautifully and any artefact around an edge would be obvious. It is the wrong trade for a photograph, where there is no flat colour to exploit and the format ends up storing sensor noise in perfect fidelity. Converting a photographic PNG to JPEG routinely cuts it by 80–90% with no visible difference.

What you give up

Transparency, which JPEG does not support. Any transparent area is composited onto white during conversion — which is usually what you want for a photograph and never what you want for a logo. If your PNG has a transparent background you intend to keep, converting to JPEG will destroy it; keep the PNG, or use WebP, which is lossy and supports transparency.

You also give up the ability to re-edit without loss. Every JPEG save discards information permanently, so if this file is a working master rather than a final delivery, keep the PNG as well.

Questions

Will my transparent background survive?
No. JPEG has no alpha channel, so transparency is flattened onto white during conversion. If you need transparency and smaller files, convert to WebP instead — it is lossy like JPEG but keeps the alpha channel.
Is any quality lost?
Yes, technically — JPEG is lossy by design. At the quality this tool uses the loss is not visible on a photograph at normal viewing size. On a screenshot or a graphic with sharp text it will be visible, and for those PNG is the correct format to keep.
Why is my converted file still large?
Because the pixel dimensions are large. Format conversion changes how efficiently pixels are stored, not how many there are. If the result is still bigger than you need, set a file-size target on the compressor or reduce the dimensions.
