JPG to PNG, explained
Create PNG copies of JPEG photos for an editor or workflow that specifically needs PNG. The converter decodes the JPG and saves those pixels in a lossless PNG container. It does not reconstruct detail lost during the original JPEG compression, and a PNG copy of a photo will often take more storage.
Select JPG, JPEG or JFIF files from your device.
Use the selected PNG output. There is no lossy-quality slider for PNG.
Convert and compare the output size before downloading the images you need.
A format change, not a quality repair
JPEG compression may already have softened fine texture or introduced ringing around text. A PNG output preserves the pixels that the browser decodes; it cannot infer the original camera or design data. If you need a better source, look for the original photo, screenshot or project file before changing formats.
When a PNG copy is useful
An editor, asset pipeline or document tool may require PNG input. A PNG copy can also be useful as a working raster when you want to avoid repeatedly re-encoding a JPEG after small edits. For final delivery, use the format the recipient requires and compare the actual files rather than assuming one is universally better.
Why the background remains visible
PNG supports transparency, but simply changing a JPG into a PNG does not remove its background. Every decoded JPEG pixel is still opaque. Background removal, object selection and masking are different editing tasks and are not performed by this converter. A white background will remain white in the new file.
Expect a different file size
The tool uses PNG encoding without a quality slider. A detailed JPEG photo may expand substantially as PNG because the two formats represent the picture differently. The result panel reports the new size. If your objective is a smaller web image, compare a WEBP output instead of treating PNG as a compression tool.
Orientation, metadata and editing copies
Native decoding applies JPEG photo orientation before the pixels are encoded. Original EXIF fields, such as camera settings or GPS information, are not transferred. Keep the original if that information matters. This is a browser raster workflow, not a promise to preserve embedded color profiles, print settings or an archival master.
