Why convert a JPG to PNG?
PNG is a lossless format — once converted, no further compression artifacts are introduced no matter how many times you re-save or re-edit the file. This makes PNG the right container when an image needs to go through more editing, be embedded in a design tool that expects PNG, or simply needs to avoid the additional generation loss that repeatedly re-saving a JPG causes. It won't undo quality already lost in the original JPG, but it stops the bleeding from that point on.
Quality isn't restored
JPG's lossy compression permanently discards some image detail when a file is saved. Converting that JPG to PNG re-encodes the pixels exactly as they currently are — it can't reconstruct detail that JPG already threw away. If you need the highest possible quality, start from the original source (a camera RAW file, a design file, or an uncompressed export) rather than an already-compressed JPG.
Why the PNG is often bigger
PNG's lossless compression can't shrink photographic detail the way JPG's lossy compression does, so a PNG of the same photo is usually noticeably larger in file size. That trade-off is inherent to the format, not a sign anything went wrong — it's the cost of losslessness.
When PNG is the right choice
PNG shines for screenshots, graphics with sharp edges and text, images that will be edited further, and anything that needs a transparent background (though a converted JPG stays fully opaque, since JPG never had transparency to begin with). For photos meant purely for final display, JPG or WebP usually remain the more practical choice.
Frequently asked questions
How do I convert a JPG to PNG?
Upload or drag in a JPG. The tool decodes it and re-encodes it as a lossless PNG immediately — click Download PNG to save it.
Will converting to PNG improve image quality?
No. JPG's compression is lossy — any detail lost when the original JPG was saved is already gone and can't be recovered by converting to PNG. Converting just re-encodes the existing pixels losslessly from that point forward, so no further quality is lost during the conversion itself.
Why is the PNG file larger than the original JPG?
PNG uses lossless compression, which generally produces larger files than JPG's lossy compression for photographic images — that's expected, not a bug. PNG is the right choice when you need pixel-perfect reproduction, transparency, or repeated editing without generation loss.
Does the JPG need a transparent background?
No — JPG never has transparency to begin with, so the resulting PNG is fully opaque. If you need to add transparency, you'll need a background-removal tool instead.
Is my image uploaded anywhere?
No. The conversion happens locally in your browser using a canvas — your JPG never leaves your device, and nothing is stored on a server.
