Output quality

Lossless decoded pixels

Lossless PNG of decoded JPEG pixels. Cannot recover detail lost in the original JPEG; output may be larger.

Before you convert

PNG cannot recover detail already lost in the original JPEG and may produce a larger file.

Store a decoded JPEG without another lossy encoding step

JPG to PNG decodes a JPEG and saves the resulting pixels in a PNG. It is useful for compatibility with an editing or publishing workflow that needs PNG, but it is not an image-restoration process.

PNG uses lossless compression for the pixel data it receives. Compression artifacts already present in the JPEG remain part of those pixels. The output may also be larger because PNG and JPEG compress photographic content differently.

Useful situations

Prepare a JPEG for software that requires PNG input.
Avoid another JPEG compression step when saving a decoded image for further work.
Create a PNG copy before editing while keeping the original JPEG as a reference.

How to use JPG to PNG

Choose a JPG or JPEG file. No output-quality setting is needed for this conversion.
Run the converter and check the preview, orientation, and output file size.
Download the PNG. Compare against the source rather than assuming that a larger file contains more detail.

What to expect

The output contains decoded image pixels, not the JPEG’s compressed bitstream or original editing layers.
Existing blur, ringing, and compression blocks are not removed.
Changing the format does not automatically remove a background or make opaque pixels transparent.

Frequently asked questions

Does JPG to PNG improve a blurry photo?

No. Lossless output means the newly decoded pixels are stored without another JPEG compression stage; it does not recover a sharper source.

Why can a converted PNG be much larger than its JPEG?

JPEG discards some information to compress photographs efficiently. PNG stores decoded pixels losslessly, which often takes more space for detailed photos.

Will converting JPG to PNG remove the background?

No. PNG supports transparency, but this converter does not identify or remove background pixels. Background removal is a separate editing operation.
