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 WebP?
WebP is a modern image format from Google that produces files 25–35% smaller than JPG or PNG at similar quality, with support for transparency and animation.
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 webp 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.
