Convert PNG to WebP
Convert PNG images to WebP online. Same crispness, dramatically smaller files — the modern format for the modern web.
About the PNG to WebP
WebP offers PNG-class quality at a fraction of the size — typically much smaller for graphics with transparency, far more for photos. This converter runs the browser's native WebP encoder on your PNGs, preserving alpha channels, ready for faster page loads.
How it works
The converter runs the browser's native WebP encoder over your decoded PNG pixels, preserving the alpha channel and, at 90%+ quality, staying visually indistinguishable from the lossless original. Graphics with transparency typically shrink noticeably; opaque photos shrink even more.
How to use it
Drop up to 10 .png files, adjust the quality slider if you like (90 is a safe default), and convert. Preview each result over the transparency checkerboard, then download files or a ZIP.
Supported formats & limitations
Accepts .png up to 30MB each, 10 per run; output is .webp with alpha preserved. Every current browser renders WebP; very old enterprise software may not — that's what the PNG→JPG route is for.
Common use cases
The go-to move for page-speed work: converting logo files, UI assets, icons and screenshots from PNG to WebP routinely wins a Lighthouse performance point. Also used to slim app bundles and design-system asset folders.
Frequently asked questions
How private is PNG to WebP?
Everything runs locally in your browser via the Canvas API. Your picture never leaves your machine — there is no upload step at all, so processing is as private as working in an offline editor.
Which file types are supported?
PNG files up to 30 MB each are accepted. Drop in one file or a whole batch (paste and drag also work), check the preview, and export in the format shown at the download step.
How many images can I process at once?
There are no artificial limits: use it as often as you like, free. Practical caps are 30 MB per image and 10 files per batch, and outputs stay watermark-free.
Can I fine-tune the result before downloading?
You can adjust WebP quality. Results are previewed after processing, so tweak values and re-run until the output looks right.
