Higher quality means a larger file. WEBP is a lossy format — some detail is discarded to reduce file size, more so at lower quality settings.
How it works
- Drop one or more PNG images.
- Choose a quality level — transparency is preserved.
- Download each WebP individually or all together as a .zip.
Frequently asked questions
- Are my images uploaded to a server?
- No. Every image is converted entirely on your device.
- Does WebP keep my PNG's transparency?
- Yes — WebP supports an alpha channel just like PNG, so transparent areas are preserved, not filled in.
- Is this lossless?
- This tool uses WebP's lossy mode with an adjustable quality setting, which typically gives a much smaller file than PNG at a visually similar quality.
