If your PNG files are used on websites, docs, or marketing pages, converting them to WebP can often reduce size much more effectively than trying to keep PNG and squeeze it harder.
Best-fit scenarios
Converting PNG to WebP is often a good choice for:
- screenshots
- blog illustrations
- product UI images
- website graphics without strict archival requirements
When to keep PNG
You may want to keep PNG if:
- you need a source asset for future editing
- another tool in the workflow specifically expects PNG
- your design handoff requires the original format
For publishing and delivery, WebP is often the better output. For source storage and editing, PNG may still be the better master file.
A simple decision rule
- Need a lighter delivery file: use
WebP - Need a stable editable source asset: keep
PNG
Why local conversion helps
Converting locally in the browser means you can test multiple outputs without sending original assets through another upload step first.
WebP does not have to replace PNG everywhere
One common mistake is thinking that converting a file to WebP means the PNG version should disappear from the workflow completely. In practice, the two formats can play different roles. PNG can remain the source or editable asset, while WebP becomes the delivery format for web pages, blog publishing, and lighter visual distribution. That separation usually makes the workflow clearer rather than messier.
Try it
Open the image compressor tool, import your PNG file, and choose Convert to WebP.
If you want the broader format decision first, compare formats in JPG vs PNG vs WebP. If the file is mainly for a webpage, also read when to use WebP for website images.
