Why convert PNG to WebP?

WebP typically encodes the same image 25–35% smaller than PNG while keeping full transparency support, which makes it the default choice for web assets today. Every modern browser renders WebP, so for most sites the only reason PNG files are still shipped is that nobody converted them.

Conversion happens entirely in your browser — no upload, no queue, no watermark. Drop in as many files as you like and download them individually or as a zip.

Frequently asked questions

Does WebP keep PNG transparency?
Yes — WebP supports a full 8-bit alpha channel, so transparent PNGs convert without any visual change. Unlike JPEG, no background flattening is needed.
Are my images uploaded anywhere?
No. Conversion happens inside your browser using the canvas API and a Web Worker — files never leave your device. There is no upload step, no queue and no file size limit beyond your machine's memory.
Is EXIF metadata kept in the converted image?
No — and that's a feature. Re-encoding through the canvas strips all metadata: GPS location, camera model, timestamps and color profiles. The output contains pixels only, which is usually what you want before sharing an image publicly.
Can I convert many images at once?
Yes. Drop or paste any number of files; each is converted in the background with its own progress and download button, and you can grab everything at once as a .zip archive.
Why did my image get re-compressed even converting PNG to PNG?
The converter always decodes to raw pixels and re-encodes, which is also how metadata gets stripped. For lossless targets (PNG, and GIF within its 256-color limit) the pixels stay identical; for JPEG and WebP the quality slider controls the trade-off.
