Turn a finished JPG into a lossless PNG you can keep editing without losing more detail.
Swap: PNG to JPGA JPG is a finished picture. A PNG is a working copy you can keep editing without paying for it in quality.
Every time a JPG is opened, edited and saved again, the encoder throws away a little more detail: edges soften, small text gets a halo, skin turns slightly blotchy. Turning the file into a PNG once ends that. From then on, crops, rotations and annotations cost nothing, because PNG stores the pixels exactly as they are.
Design tools, print shops, screenshot editors and a fair number of upload forms list PNG as the accepted type and reject a .jpg outright. Converting first takes a second and saves hunting for another tool or renaming the file and hoping.
A screenshot of a chart, a scanned line drawing or a photo of text was never a good fit for JPG: its blocking shows up on exactly that kind of hard edge. Once the file is a PNG, cropping it or sharpening it does not add a second layer of artefacts on top of the first.
Be clear about what this step can and cannot do before you start.
The detail a JPG already discarded is gone; no converter can put it back. What you get is an exact copy of the pixels that survived, in a format that will not lose any more. If the photo looks soft on the upload, it will look equally soft in the PNG — but not softer after the next three edits.
JPG cannot store transparent pixels, so there are none to carry over: the PNG keeps the white or coloured rectangle around the picture and simply marks every pixel as fully opaque. To cut a background out you need an editor; converting formats will not do it.
Expect roughly two to five times the size, more for a very smooth photo. PNG compresses without loss, which is exactly why it cannot match the weight of a lossy JPG. The Quality field is ignored for PNG output for the same reason — there is nothing to dial down.
Phone photos often store their rotation as a tag rather than in the pixels. That tag is applied on the way through, so a sideways-looking file comes out upright with width and height swapped to match. Camera model, GPS position and the rest of the metadata are not carried into the PNG.
Three steps, no account and nothing to install.
Drag the file onto the box, click it to browse, or copy the picture and paste it with Ctrl+V (Cmd+V on a Mac). One file per run, up to 25 MB.
Leave the width empty to keep the original pixels exactly. Type a width if the PNG is going into a fixed spot, such as a 1200 px blog header; the height follows the aspect ratio and the image is never enlarged.
The preview shows the result with both file sizes side by side, so the weight increase is no surprise. One click saves the PNG next to the original — keep the JPG too, in case you need the smaller version later.
Small decisions now save you an awkward re-run later.
If a crop or a rotation is still on your list, do it on the PNG. Cropping a JPG and saving it re-encodes the whole frame a second time; doing the same work on a PNG leaves every remaining pixel untouched. Same for annotations, arrows and red circles.
PNG keeps its promises by storing more data, so a folder of photographs turned into PNG becomes enormous and uploads much more slowly. For a picture that only has to be looked at, stay in JPG or read how to shrink an image instead. PNG is for editing, for graphics and for archives.
Editing a PNG and then exporting a compact JPG for email or a web page is a perfectly good ending. The PNG to JPG converter does that step, and it is worth doing once from the finished PNG rather than saving over the old JPG again and again.
Yes. There is no account, no trial, no credit card and no watermark on the PNG you download, and you can convert as many files as you like. A short rate limit keeps one visitor from occupying the server for everyone else.
No. The compression happened when the JPG was saved and the missing detail is gone for good. What the PNG gives you is an exact, lossless copy of the pixels that survived, so every further crop, rotation or annotation is free of new artefacts instead of adding to the old ones.
PNG stores every pixel and compresses them without throwing anything away, while JPG discards detail on purpose. Two to five times the size is normal, and photographic images grow the most. If weight matters more than lossless editing, keep the JPG or export a smaller JPG from the finished PNG.
Up to 25 MB per file, and the image itself up to 50 megapixels, which covers a full-frame camera photo. If a file is refused, scale it down first — a width of 4000 px or less is plenty for any screen.
Files are processed on our server and not stored. The JPG is converted as it arrives and only the PNG is sent back to your browser.
