Convert PNG to WebP

PNG files are lossless — and often far bigger than they need to be. WebP keeps your transparency and sharp edges while usually cutting the file size dramatically. Convert here, free, without uploading your file.

Why PNG files are so large — and why WebP helps

PNG stores every pixel exactly, which is perfect for screenshots, logos and interface graphics, but wasteful for anything photographic that slipped into PNG format. WebP supports the same transparency (alpha channel) as PNG, plus much stronger compression. Screenshots and graphics commonly shrink by half or more; photographic PNGs can shrink far further, because they never belonged in a lossless format.

How to convert PNG to WebP

Choose your PNG — drop it above or click to browse.
WebP is pre-selected. At the default 92% quality, edges and text stay crisp; transparency is preserved.
Convert, compare, download — the result panel shows both sizes before you save the .webp file.

Honest notes

Transparency is kept — transparent pixels in your PNG remain transparent in the WebP.
Quality below 100% is lossy. For pixel-perfect UI assets where every edge must be exact, compare the preview carefully, or keep the PNG.
Need the opposite? If a portal demands PNG, this is not your tool — but if it demands a small file, also try the KB compressor.

Privacy

Conversion runs 100% locally in your browser using its built-in image technology. Your image is never uploaded to ImageConvertPro or any other server, and nothing about the file is stored. The downloaded file always has the correct extension and type for the format you chose.

Frequently asked questions

Does WebP really keep my transparent background?

Yes. WebP has a full alpha channel like PNG. The converter preserves it, and the result preview sits on the page background so you can see the transparency survived.

Why did my screenshot barely shrink?

Simple screenshots with few colours are already efficient in PNG. Photographic or gradient-heavy PNGs shrink the most. The tool always shows the real sizes, so you can decide whether converting is worth it.

Is WebP safe to use on my website?

All modern browsers support WebP. If you must support very old browsers or tools, keep the PNG as a fallback — or convert a copy and compare.
