PNG to WebP output checks
- Check the output KB or MB against the upload limit.
- Verify pixel dimensions and whether transparency is preserved.
- Open at 100% size to check text and edge sharpness.
Processing method
The browser decodes the source pixels and encodes them in the selected format. Lossy output changes with quality, and JPG cannot preserve transparency.

Frequently Asked Questions
Does PNG transparency stay transparent in WebP?

Is WebP suitable for logo PNG files?
For web display, WebP can be useful. Keep the original PNG separately if you need an editable source file.
Is WebP always smaller than PNG?
Often, but not always. Very simple graphics can be similar in size or occasionally larger after conversion.
