Phone, tablet, or computer — it runs in the browser you already have.
What does converting JPG to PNG do?
JPG and PNG store images differently. JPG uses lossy compression that discards fine detail to stay small — great for photos, but every re-save loses a little more. PNG is lossless: it keeps every pixel exactly and never degrades no matter how many times you save. Converting a JPG to PNG rewraps the same picture in that lossless container, so from that point on your edits and exports add no further compression, and the file is accepted by the many tools and upload forms that require PNG. Because this tool runs entirely in your browser, the image is converted on your own device and is never uploaded.
When should you convert JPG to PNG?
Convert when a workflow or platform needs PNG. Design tools, app icon pipelines, and some content systems only accept PNG. You also convert before editing an image repeatedly, since PNG will not accumulate JPG artefacts with each save. Screenshots, diagrams, and logos that arrived as JPG belong in PNG, where their flat colour and sharp edges stay crisp. One honest note: converting does not restore detail JPG already threw away or add transparency the JPG never had — it prevents further loss going forward.
How to get the best results
Start from the highest-quality JPG you have, since PNG can only preserve what is already there. Expect the PNG file to be larger than the JPG — that is the cost of lossless storage, especially for photographs with lots of colour. For photos you mainly want to view or share, staying with JPG (or converting to WebP) keeps files small; choose PNG when you specifically need lossless editing or PNG compatibility. If the PNG is only for the web and size matters, you can compress it afterwards.
Limitations to be aware of
PNG is lossless, so a photograph saved as PNG is often several times larger than the JPG it came from — that is expected and not a bug. Converting cannot undo JPG’s earlier compression: any blockiness or softness already baked into the JPG stays in the PNG. And a JPG has no transparency to carry over; the PNG will have a solid background unless you edit it. For flat graphics and screenshots, PNG is ideal; for large photo libraries you just want to store, it is usually the wrong choice.
Common mistakes and how to avoid them
The most common misunderstanding is expecting PNG to improve a JPG’s quality; it preserves, it does not restore, so start from the best source. Another is converting a big photo to PNG and being surprised by the larger file — that is lossless storage working as intended. People also sometimes expect a transparent background to appear; JPG never stored one, so you would have to remove the background separately. Keep the original JPG in case you need the smaller file later.
Using it on mobile and desktop
On a phone, convert a JPG to PNG to meet an app or upload requirement without any software — everything runs locally. On a computer, drop a batch of JPGs and convert them all to PNG at once for a design project or a system that only accepts PNG. Because there is no app to install, the same link works on every device, and nothing you add is ever uploaded.
Why convert here instead of another site?
Most online JPG-to-PNG converters upload your files to a server, convert them there, and promise to delete them later. This tool never uploads anything — the conversion happens inside your browser, so images that may be personal or private stay on your device from start to finish. There are no watermarks, no sign-up wall, and no cap on how many images you convert. It is faster too, with no upload-and-wait step, and it works offline once the page has loaded.
