About PNG
PNG keeps every pixel exactly as it was and can store transparent areas. Great for screenshots and logos. For photos, though, the files get big.
About WebP
WebP is Google's format for the web. Sites love it because the files are small, but a lot of desktop apps, older editors and upload forms still refuse it.
Frequently asked questions
Are my photos uploaded?
No. Your browser does the conversion on your own computer or phone, and the images never reach our servers. That makes it safe for private photos too.
Will converting PNG to WebP reduce quality?
WebP is a lossy format, but at 90% quality the difference is invisible to almost everyone. Lower the quality slider for smaller files.
Can I convert several PNG files at once?
Yes. Select or drop as many files as you like, then download them one by one or all together as a ZIP file.
