Frequently asked questions
Why convert PNG to WebP?
WebP keeps transparency like PNG but produces files that are typically 60–80% smaller, which makes it the best format for websites.
Does converting PNG to WebP lose quality?
At the default settings the result is visually indistinguishable from the PNG — WebP preserves transparency and sharp edges extremely well, and the file is still usually a fraction of the original size.
Are my images uploaded to a server?
No. The image is processed locally in your browser. Processing time depends on its dimensions, format and your device; large files can exceed the browser’s available memory.
Will compressing reduce image quality?
Compression can remove visible detail. Check the output at full size, especially fine text, edges and gradients. Use a lighter compression level or keep the original when preserving detail is more important than size.
Can I convert many files at once?
Yes. Drop any number of files and each is converted independently — there are no batch limits or daily quotas, because processing runs on your own device.
About this tool
WebP was designed by Google as a modern replacement for both JPG and PNG on the web, and PNG-to-WebP is where it shows its biggest wins: the same transparency support at file sizes typically 60–80% smaller. For logos, UI assets, screenshots and product images with transparent backgrounds, WebP loads dramatically faster with no visible difference. Every current browser — Chrome, Safari, Firefox, Edge — renders WebP natively, so for website use there is little reason left to serve PNG.
Conversion happens entirely in your browser: each PNG file is decoded locally and re-encoded as WebP using the browser’s own image engine, so nothing is uploaded and the result is ready the moment you drop the file. Batch conversion works the same way — add as many files as you like and download each result individually.
There is no server upload quota, but browser memory, supported formats and device performance limit what can be processed. Large files or batches may fail on a phone. Try a smaller batch or image, and keep your originals.
