FAQ
- Are my PNG files uploaded anywhere?
- No. Decoding and re-encoding happen locally via FileReader + Canvas. No network requests are made.
- Will transparency be preserved?
- Yes. The PNG alpha channel is preserved end-to-end: WebP supports an 8-bit alpha channel, so transparent areas in your PNG remain transparent in the resulting WebP.
- Lossy vs lossless — which should I pick?
- Lossless WebP keeps every pixel identical to the original PNG but produces a larger file. Lossy WebP with quality 75–90 is usually indistinguishable from the source and dramatically smaller. Use lossless for archival, lossy for the web.
