FAQ

Good to know.

How do I convert JPG to PNG?
To convert JPG to PNG, drop your .jpg files onto the Pixasur converter and it re-encodes each one to lossless .png in your browser. The process is client-side, so no image is uploaded to any server.
Does converting JPG to PNG improve quality?
Converting JPG to PNG does not add back detail that JPEG compression already discarded, but PNG stores the result losslessly so no further quality is lost. It is useful when you need a lossless master or a format that supports transparency.
Will the PNG file be larger than the JPG?
Yes, a PNG converted from a photo is usually several times larger than the original JPG, because PNG is lossless and does not compress photographic detail as tightly. PNG is best for graphics, screenshots, and images you plan to edit.
Is the JPG to PNG converter free?
Yes, the Pixasur JPG to PNG converter is completely free with no sign-up and no watermark, and there is no limit on the number of files. Batch conversion and zip download are included.
Does the JPG to PNG converter work on a phone?
Yes, the Pixasur JPG to PNG converter runs in any modern mobile browser on Android or iPhone, and your photos stay on the device because the conversion happens in the browser. No app install is needed.
