PNG to WebP Conversion FAQ
Does the PNG to WebP converter keep transparency?
+
When WebP supports an alpha channel (PNG, WebP, GIF) and the original PNG had transparency, we keep it. Converting to a format without transparency (JPG, BMP) fills transparent areas with white by default.
Can I batch-convert PNG images to WebP?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Will the converted WebP have the same dimensions as my PNG?
+
Yes — pixel dimensions are preserved by default. If you want to resize during conversion, use the WebP resize tool after the conversion finishes.
Is my PNG image private when I convert it?
+
Yes. Uploads travel over HTTPS, nobody reads the contents, and nothing is shared. Your uploaded PNG and the resulting WebP are deleted from our servers automatically about 24 hours after the conversion, which leaves time to download the result.
Why is my converted WebP file larger than the original PNG?
+
If WebP is lossless and PNG was lossy (or vice versa), file size will change. PNG (lossless) is typically larger than JPG (lossy) for photographs but smaller for solid-color graphics and screenshots.
Can I convert PNG to WebP on my phone?
+
Yes. The converter is mobile-responsive and processes images server-side, so you can convert PNG to WebP from any iPhone or Android device without using local storage.
