PNG → WEBP Selection criteria and conversion limits
When it fits
Use this to publish transparent web images while choosing lossy size/quality or lossless WebP when the browser supports it. Keep PNG for editing and archiving, and create WebP as the delivery copy.
What changes and what to check
Lossy mode uses quality and target KB; lossless mode ignores the target and verifies an actual VP8L output. Transparency can remain, but animation and EXIF/ICC are not preserved, so check transparent edges and size in the target browser.
Frequently asked questions
Are uploaded images sent to a server?
No. All processing happens inside your browser and images are never sent to an external server.
Why convert to WEBP?
WEBP produces smaller files at the same visual quality, which helps reduce page weight and speed up website loading.
Can I convert multiple files at once?
Yes. You can convert up to 20 files at once with the same settings and download them individually or all together as a ZIP.
