Convert JPG to PNG
Editing the same JPEG over and over grinds quality away, because every save re-compresses the picture. Switching to PNG freezes it: from that point on, no edit or re-save costs you anything. This converter does the switch instantly and free of charge, entirely on your computer - your image is never transmitted.

How it works
- Drop a JPG (or several) onto the converter.
- Preview the result - pixels are copied across exactly, so it should look identical.
- Download your PNG files. Names are preserved with the new extension.
Worth knowing
Be clear about what this conversion does and does not do, because half the pages ranking for it get it wrong. A JPEG has already been through lossy compression; whatever softness or blockiness it picked up is baked into the pixels. Wrapping those pixels in a PNG container does not sharpen anything, restore detail or "upgrade" the image. What it does is draw a line: PNG is lossless, so every future save, crop, annotation or export from this file will be a perfect copy. The damage stops accumulating exactly here.
That makes JPG-to-PNG the right first step in an editing workflow. Designers pulling a photo into a mockup, developers preparing assets that will be sliced and re-exported, anyone adding arrows and callouts to an image in repeated passes - each round trip through a JPEG would add another layer of artifacts, especially around text and hard edges added during editing. Do those rounds in PNG and the tenth version is as clean as the first.
PNG also gives you an alpha channel, which JPEG lacks. The converted file arrives fully opaque, but once it is a PNG you can erase the background, cut out a subject or add soft shadows in any editor - or in the background remover on this site - and the transparency will actually be saved. That is the other common reason to convert: an upload target or a design tool that insists on PNG input before it will let you work with transparency at all.
Expect the file to grow, often three to five times. Lossless storage of photographic pixels is expensive, and that is normal. The PNG is a working format; when you are finished editing, export a JPEG or WebP for final delivery and keep the PNG as your clean master.
Re-saving a JPEG at quality 90 ten times in a row measurably degrades it - generation loss compounds on every save. Convert to PNG before an edit-heavy session and the picture is bit-for-bit stable no matter how many times you save, which is the actual reason professionals make this conversion.
What this tool will not do
- It will not recover detail the JPEG already lost - compression artifacts present in the source are copied faithfully into the PNG.
- It will not add transparency by itself; the PNG starts fully opaque until you remove the background in an editor.
- It will not reduce file size - the PNG will almost always be several times larger than the JPG it came from.
Questions people ask
Does converting JPG to PNG improve image quality?
No, and any site claiming it does is misleading you. The pixels are copied exactly as they are. The benefit is protection going forward: PNG saves are lossless, so subsequent edits never introduce new compression damage.
Why is my PNG so much bigger than the original JPG?
PNG stores every pixel without discarding anything, and photographs are dense in detail. A three- to five-fold size increase is typical. Treat the PNG as an editing master rather than something to embed on a web page.
Will the PNG have a transparent background?
Not automatically - JPEGs have no transparency, so the converted PNG is solid edge to edge. The format now supports it, though, so a background remover or any editor with an eraser can make regions transparent and the file will keep them.
When should I actually use PNG instead of JPG?
During editing, for anything with sharp text or line art, for images needing transparency, and for master copies you will export from repeatedly. For final photos going into an email or onto a site, JPEG or WebP remains the better delivery choice.
Is anything lost during the JPG to PNG conversion itself?
Nothing. The decode-and-store step is exact; every pixel value in the JPEG appears unchanged in the PNG. It is one of the few conversions with zero quality cost in this direction.
Can I convert several JPGs to PNG in one go?
Yes, drop in as many as you need. Because processing is local, a large batch is limited only by your machine, and the files download together as a ZIP.
