Converting a JPG to PNG gives you a lossless container: from that point on, every save keeps the pixels exactly as they are. What it cannot do is undo the compression that already happened. The detail a camera or an export step threw away when the JPG was created is gone, and no format change brings it back. Convert when the file has editing ahead of it, not to repair a file that already looks rough.
This is the most common misunderstanding. JPG discards data permanently when it compresses. A PNG made from a blurry or blocky JPG is a lossless copy of that blurry, blocky image — same artefacts, larger file. If you need a clean version, go back to the original source.
Every time a JPG is opened, edited, and saved again it is recompressed, and the artefacts accumulate. PNG is lossless, so converting before a round of edits means the file stops degrading with each save. This is the strongest practical reason to convert.
A JPG is already heavily compressed. PNG stores those same pixels losslessly, artefacts included, so the result is usually several times larger. That is the expected trade, not a fault in the conversion.
No. It preserves whatever quality the JPG already has and prevents further loss from future saves, but it cannot recover detail that JPG compression already discarded. Quality improvement has to come from a better source file.
Not by itself. JPG has no transparency to carry over, so the PNG starts fully opaque. To actually get a transparent background you need to remove it — that is a separate editing step, not something the format conversion does.
Because PNG is lossless. JPG reached its small size by throwing detail away; PNG stores every remaining pixel exactly, so the file grows. For photographic images a several-fold increase is normal.
No. The conversion runs entirely in your browser, so the files never leave your device and there is no upload to wait for.
Changing a JPG into a PNG sounds like a small step, but people do it for very different reasons: a design app that only imports PNG, a template that asks for PNG, a plan to edit the image several times, or the hope of getting a transparent background. Some of those goals the conversion meets on its own, and some need another step. This guide explains what the converter actually does to your file and how to get what you were after.
Your browser decodes the JPG into plain pixels, draws them onto a canvas, and saves that canvas as a PNG. The pixels in the new file are exactly the pixels the browser decoded, including any blocky areas, colour noise, or ripples around text that the JPG already had. Nothing is sharpened, smoothed, or cleaned up along the way.
That is also why there is no quality slider on this page. PNG is lossless, so there is no trade-off between size and quality to tune; the browser's PNG encoder simply stores every pixel. One side effect is worth knowing: because the image is redrawn, the EXIF block from the JPG, which can include camera details, capture time, and sometimes GPS location, is not copied into the PNG. If you are sharing a phone photo publicly, that is usually a welcome change.
A PNG made from a JPG is fully opaque. The white or grey backdrop behind a product, a signature, or a logo is still there, now stored losslessly. Converting first and removing the background later gains you nothing, so skip that detour when transparency is your goal.
Open the original JPG in the background remover instead. It cuts out the subject in your browser and saves the result as a PNG with a transparent background, named ShotEdit.png, so the format change happens as part of that step. Use this converter when you need the whole picture kept intact as PNG, and the background remover when you need parts of it to disappear.
A few situations clearly justify it. Some design tools, slide templates, sticker makers, and game or app asset pipelines accept only PNG. If you are going to crop, annotate, and re-save an image several times, converting once at the start stops each save from adding another round of JPG compression. And if you are building a master copy to produce several crops or sizes from later, a PNG master keeps every derived version one generation away from the original.
It is not worth it when the JPG is going straight onto a website, into an email, or onto a social platform that will recompress whatever you upload. In those cases you only make the file heavier. After converting, check the size readout: each file shows its original size, the converted size, and the change as a percentage, shown in red with a plus sign when the file grew. For camera photos, a PNG several times the size of the JPG is normal.
The simplest way to cut a large PNG is to reduce its dimensions. A full-resolution phone photo rarely needs to stay that big for a slide or a document, and the image resizer keeps the file as PNG while scaling it down, adding a -resized suffix so your original is not overwritten. Halving the width and height leaves a quarter of the pixels, which usually shrinks a PNG more than any other change that keeps the format.
The image compressor can also shrink a PNG while keeping it as PNG, by reducing the number of colours in the image. That works very well on screenshots and flat graphics. On photographs, reducing colours can cause visible banding in skies and skin tones, so compare the result before you replace anything. If the destination accepts JPG after all, the PNG to JPG converter will give you a much smaller file.
Select or drop as many files as you like; files ending in .jpg or .jpeg, or reported by the browser as JPEG images, are accepted, and anything else is left out with a short notice. Every file in the list is converted in turn, keeps its name with a .png extension, and can be downloaded individually or with Download all, which saves the files one by one rather than as a single archive.
If a file shows the message that the image could not be loaded, the browser was unable to decode it. The usual causes are a damaged download or a file that is not really a JPG despite its name, such as an image from another format that was renamed by hand. Open it in an image viewer to confirm what it is, or re-export it from the original app. Everything runs locally, so a failed file is never sent anywhere for inspection.
