How to convert JPEG to PNG
Converting JPEG to PNG is the right choice when you need to preserve image quality exactly for subsequent editing, add transparency to a photo, or use an image in a context where re-saving as JPEG would introduce additional compression artifacts. PNG uses lossless compression, so once you have the PNG, no further quality loss occurs no matter how many times you save it.
This conversion runs entirely in your browser via WebAssembly. Your JPEG is decoded to raw pixels and re-encoded losslessly as PNG. No file is uploaded to a server and there is no size limit imposed from our side. Note that the output PNG will typically be several times larger than the input JPEG, because PNG cannot match JPEG's lossy compression efficiency for photographic images.
Upload your JPEG
Click to select or drag in your .jpg or .jpeg file. The file is processed locally in your browser.
Optionally set PNG compression level
Higher PNG compression takes longer but produces a smaller file. The image quality is identical at all compression levels because PNG is lossless.
Convert
The WebAssembly codec decodes the JPEG and encodes the raw pixel data as PNG. Progress is shown for large files.
Download the PNG
Save the .png file. Open it in your image editor to verify it looks correct, then use it wherever PNG is needed.
Frequently asked questions
Why would I convert a JPEG to PNG?
The main reasons are: (1) you need to edit the image multiple times without accumulating quality loss each save; (2) you need to add transparency; (3) the image will be used in a context (like a presentation template) that benefits from lossless quality; or (4) you are creating a source file from which JPEG exports will be made.
Does the PNG have better quality than the JPEG?
No. Converting JPEG to PNG preserves the existing quality exactly, but cannot recover detail that JPEG compression already discarded. If the JPEG had artifacts, those same artifacts appear in the PNG. PNG prevents further quality loss on subsequent saves.
Why is the output PNG so much larger than the JPEG?
JPEG compresses photographs very aggressively by discarding fine detail. PNG must preserve every pixel exactly, which requires more storage space for photographic content. Expect the PNG to be 3 to 10 times larger than the source JPEG.
Is my image uploaded to a server?
No. The conversion uses WebAssembly running in your browser. Your file never leaves your device.
Should I use JPEG or PNG for my website images?
For photographs: JPEG is usually the better choice for web delivery because smaller file sizes load faster. For logos, icons, graphics with transparency, and images with sharp text: PNG is preferred. Consider WEBP as a modern alternative that handles both cases well.
