Create a lossless PNG working copy from JPG before annotation, design, or repeated editing.
Or choose up to 100 files. You can also paste an image.
Metadata and GPS are removed from converted files.
Converting does not restore detail already removed by JPG compression, but PNG prevents another lossy save while you edit, annotate, or composite the image.
The same settings apply to the entire queue, so a group of images leaves with consistent dimensions and output quality.
Drag files into the converter or use the file picker. Unsupported extensions are skipped with a clear message.
Resize when needed. PNG uses lossless encoding, so it does not need a quality slider.
Review each thumbnail and file size. Download one output at a time or package multiple results in a ZIP.

Yes. Files are decoded and encoded in your browser. They are not uploaded to our servers or stored by ConvertPics.
Yes. The converter accepts up to 100 files in one batch and processes them sequentially. Finished files can be downloaded individually or together as a ZIP.
No. The browser renders decoded pixels onto a fresh canvas, so EXIF, GPS, camera, profile, and comment metadata is not copied to the converted file.
Yes. Enter a width, a height, or both. Keep ratio is enabled by default so the image fits within your requested dimensions without stretching.
