Convert JPG to PNG
Convert JPG to PNG for a lossless working copy. Batches run up to 10 files, 20MB each. Processing happens on your device, not on a server.
Converting JPG to PNG does not sharpen or clean up the image. PNG is lossless, so it stores whatever it receives without adding further damage, but existing JPG artifacts stay exactly as they were. The file usually grows larger too, since PNG cannot compress photographic detail as tightly as JPG.

JPG vs PNG
JPG
JPG is the everyday photo format, small and accepted almost everywhere you upload an image. It stays lossy though, and it has no transparency channel at all.
PNG
PNG stores every pixel without throwing anything away, so nothing further degrades once the swap is done. That same thoroughness is exactly why the file usually gets bigger.
Why convert JPG to PNG
Two reasons make this conversion worth doing. Editors benefit from a lossless working copy, so repeated edits stop stacking extra compression on top of the original loss. A tool or template that only accepts PNG input is the other common trigger. What this conversion will not do: it cannot sharpen a blurry photo or clean up JPG artifacts already baked into the pixels. PNG stores whatever it receives, flaws included, just without compressing them further. Expect the file to grow, often several times larger, because PNG keeps every pixel instead of discarding data the way JPG does. It also adds no transparency. A JPG never carried an alpha channel, so a solid background stays solid after the swap. Want a cleaner source image? Start from an earlier, less compressed copy if one still exists. Want a transparent background instead? Use a background removal tool, not this converter.
PNG stores your JPG losslessly, adding no further compression damage.
File size usually grows. Existing JPG artifacts stay exactly as they are.
Private by design
This conversion runs locally, your file is never sent to a server.
FAQ
Does converting to PNG improve the quality?
No. PNG conversion adds no further damage, but it also cannot remove artifacts already baked into the JPG. The image will look the same, just stored differently.
Will the file get bigger?
Usually yes. PNG cannot compress photographic detail as tightly as JPG, so the file size typically grows even though the image looks the same.
Does this create transparency?
No. A JPG has no alpha channel to begin with, so a solid background stays solid after conversion. Adding real transparency needs a background removal tool, not a format conversion.
Is it fine to convert just because I want a PNG file?
Yes, that alone is a fine reason. Just do not expect the image to look sharper or cleaner afterward, conversion only changes the container, not the pixels.
