PNG to WebP Questions
Are my PNG files uploaded to a server?
No. The conversion runs in your browser using WebAssembly, so your PNG files never leave your device. Nothing is stored, and the page keeps working even on a slow connection.
Will converting PNG to WebP reduce quality?
WebP is a lossy format, so a little detail is traded for a smaller file. At the default quality of 85 the difference is very hard to see. Move the quality slider up if you need the result to be closer to the original.
Is transparency kept?
Yes. WebP supports full transparency, so soft edges, shadows and see-through areas come through intact.
Will the WebP file be bigger or smaller?
Usually smaller. WebP is one of the most efficient formats available; the exact saving depends on the image and the quality you choose.
Is the PNG to WebP converter free?
Yes. There is no sign-up, no watermark and no daily limit. Convert up to 50 files per batch, as many times as you like.
