PNG to WebP Converter

FloxerFile lets you convert a PNG image into a WebP file instantly. WebP typically produces much smaller files than PNG while still supporting full transparency, making it a great choice for faster-loading websites. No software, no sign-up, just upload and download.

Features

• Real lossy re-encode by default

  The output uses WebP's standard lossy compression, not a lossless mode — an honest tradeoff that produces much smaller files than the source PNG.

• Transparency carried over

  Unlike a JPG conversion, WebP supports alpha — any transparent areas in your PNG are preserved.

• Meaningfully smaller files

  WebP's compression is significantly more efficient than PNG's for most images, often 25-50% smaller.

• Rejects invalid PNG uploads

  Invalid or unreadable PNG files are rejected with a clear error.

Supported formats

Output format: .webp

Frequently asked questions

Does converting to WebP keep my PNG's transparency?

Yes — WebP supports an alpha channel just like PNG, so transparent areas carry over correctly.

Is this a lossless conversion, since PNG is lossless?

No — the output uses WebP's standard lossy compression, which is what makes the file meaningfully smaller than the PNG source. This is a real quality tradeoff, not a lossless re-wrap.

How much smaller will the WebP file be?

It varies by image, but WebP typically produces files 25-50% smaller than an equivalent PNG.

What's the file size cap for this converter?

Files up to 20 MB are supported.
