How to convert JPG to PNG
JPG and PNG are the two most common web image formats, each suited to different content. JPG uses lossy compression optimized for photographs, while PNG uses lossless compression best suited for graphics, logos, screenshots, and images with transparency. Converting JPG to PNG is the standard step before adding a transparent background, editing the image repeatedly without quality loss, or using it in a context where crisp edges matter.
This conversion runs entirely in your browser. Your JPG is decoded to raw pixel data and re-encoded as PNG using WebAssembly. No file is uploaded to a server, and there is no size limit. Expect the output PNG to be larger than the source JPG because lossless compression cannot match the efficiency of JPEG's lossy algorithm for photographic content.
Upload the JPG file
Click to select or drag in your .jpg or .jpeg file. The conversion happens locally; your file stays on your device.
Convert to PNG
The WebAssembly codec decodes the JPEG pixel data and re-encodes it losslessly as PNG. No quality is degraded during this step.
Download the PNG
Save the resulting .png file. Use it in your image editor, website, or any application that requires PNG.
Add transparency if needed
Once you have the PNG, open it in an image editor to add or remove background transparency, which is not possible in JPG format.
Frequently asked questions
Is there any quality difference between my original JPG and the converted PNG?
The PNG captures exactly the pixels present in the JPG, neither better nor worse. Quality that was lost when the photo was originally saved as JPG cannot be recovered. Future edits and saves as PNG will not introduce further quality loss.
Why is the PNG larger than the original JPG?
JPG discards fine detail to achieve small file sizes; PNG preserves every pixel. For photographs, PNG compression is much less efficient than JPG compression, typically producing files 3 to 10 times larger.
Is my image uploaded to a server?
No. The converter uses a WebAssembly image codec in your browser. Your file is processed in local memory.
Can I remove the white background from a JPG after converting to PNG?
Yes. Convert to PNG first, then use an image editor (like Photoshop, GIMP, or an online background remover) to select and delete the white background. PNG supports transparency; JPG does not.
When should I use JPG instead of PNG?
Use JPG for photographs destined for web display where smaller file sizes matter. Use PNG for logos, icons, screenshots, and any image where you need transparency or lossless quality for editing purposes.
