Format conversion
PNG to WebP
WebP is the modern web image standard: it keeps PNG transparency at a fraction of the size — especially dramatic for images with alpha. Batch-convert your PNG library to WebP and watch page load times drop.

How to use
- Drag your PNG files into the dashed box above, or click to choose files (multi-select and paste are supported).
- The tool decodes PNG and encodes WebP locally in your browser, using this page's defaults — no setup needed.
- Download results one by one or as a single ZIP; memory is released immediately after processing, with no copies left behind.
FAQ
Will my images be uploaded?
Never. All decoding and encoding for PNG to WebP runs inside your browser via WebAssembly. This site has no image upload endpoint at all, and it works offline.
Is it free? Any limits on file count or size?
Completely free — no sign-up, no watermark. PNG to WebP has no file-count or per-file size limits. Since images are processed on your device, server costs are zero and this can stay free forever.
Will quality drop?
Default quality is 85 (adjustable 0–100). WebP is lossy; repeated conversions accumulate artifacts, so convert once from the original.
Does it support batch processing?
Yes. Drop dozens or even hundreds of PNG images at once; the memory-budget scheduler processes them locally in a queue. Download individually or as a single ZIP.
Is EXIF metadata or GPS kept in the output?
No, metadata is stripped by default. EXIF and GPS data are removed from the output, so shared files never leak where photos were taken — a privacy feature by itself.
