Bulk JPG to PNG & PNG to JPG Converter: preset, controls and batch workflow

The JPG to PNG & PNG to JPG Converter keeps both format directions on one functional page, so a batch can move from the first format to the second or back again with the same familiar controls. This covers the closely related conversion intents without creating thin duplicate converter pages.

Choose the direction, add multiple source images and set the output quality where the destination format supports it. The batch image converter processes every file locally and prepares individual downloads plus a ZIP archive.

Preset summary: direction 1: JPG / JPEG → PNG; direction 2: PNG → JPG / JPEG. All selected files use the same configuration.

Common questions

Are my images uploaded to a server?

No. Image decoding, canvas processing and file generation happen locally in your browser.

Can I process multiple images at once?

Yes. The same preset is applied to every selected file, and the completed batch can be downloaded as a ZIP.

Which output format should I choose?

JPG is broadly compatible for photos, PNG supports transparent graphics, and WebP usually creates smaller web-ready files.
