    Download the result

    Save each file individually or everything at once as a ZIP.

PNG is lossless, so converting a JPG to PNG stops further quality loss when you edit and re-save an image. It is also the format many design tools, slide decks and print shops ask for.

What is JPG?

JPG (JPEG) is the most widely supported photo format. Its lossy compression keeps files small, which makes it perfect for photos, email and the web — but it does not support transparency.

What is PNG?

PNG (Portable Network Graphics) is a lossless image format with transparency support. It is ideal for screenshots, logos and graphics with sharp edges, but files are larger than JPG for photos.

Safe for confidential files

Unlike upload-based converters, ZapMorph processes files inside your browser tab. Your documents are never transmitted, stored or logged — close the tab and they’re gone.

Frequently asked questions

Is the jpg to png converter free?

Yes. Convert 1 file a day without an account, or 5 files a day with a free account. Pro removes all daily limits.

Are my files uploaded to a server?

No. The conversion runs entirely in your browser, so your files never leave your device. We only count how many files you convert — never their names or contents.

What is the maximum file size?

Up to 25 MB per file without an account, 50 MB with a free account, and 1 GB on Pro. Very large files also depend on your device’s memory.

Can I convert multiple JPG files at once?

Yes. Select several JPG files at once — up to 5 on the free plan or 50 on Pro — and download all results in a single ZIP.

Does it work on Mac, Windows, iPhone and Android?

Yes. It works in any modern browser — Chrome, Edge, Firefox and Safari — on desktop and mobile, with nothing to install.
