Controls the size-versus-quality trade-off for JPG, WebP, and AVIF — higher looks closer to the original, lower makes a smaller file.

How it works

  1. Drop your PNG files here, or select a whole folder.
  2. Each PNG is decoded and re-encoded as WebP — right in your browser, transparency intact.
  3. Raise the quality slider toward 100 for near-lossless results, or lower it for smaller files.
  4. Download the WebP files individually, or as one ZIP.

PNG is the safe default for logos and icons because it's lossless and supports transparency — but WebP does both of those too, usually at a much smaller file size, which is why it's worth converting before you ship assets to a website. This tool re-encodes PNG to WebP entirely in your browser, transparency intact, with nothing uploaded to a server. One decision is yours: lossy WebP (smaller, a tiny bit of recompression) or a higher quality setting that keeps the result close to lossless. For flat-color logos the size savings from even lossy WebP are usually dramatic and the visual difference is negligible.

Why use convert.pics?

  • Transparency carries over automatically — no flattening, no white fill.
  • Usually a significant size reduction versus the original PNG.
  • No upload: bulk-convert an entire icon or asset library locally.
  • Batch conversion and a quality slider to fine-tune the size/fidelity tradeoff.

Frequently asked questions

Does PNG to WebP keep the transparent background?

Yes. WebP supports a full alpha channel just like PNG, and the conversion preserves it exactly — nothing is filled in or flattened.

Should I use lossless or lossy WebP for a PNG?

For photos and complex images, lossy WebP at a high quality setting usually gives the best size-to-quality ratio. For logos, icons, or graphics where every pixel matters, push the quality slider toward 100 — the closer to lossless you need, the higher you should set it.

How much smaller will the WebP be?

It varies by image, but flat-color graphics like logos and icons often shrink dramatically, sometimes by more than half, because WebP compresses that kind of content far more efficiently than PNG.

Is WebP better than PNG for logos and icons?

In almost every practical sense, yes — smaller files, the same transparency support, and support in every current browser. PNG remains useful mainly as a universal fallback for very old software that doesn't recognize WebP.

Live request log

Every network request this page and its conversion workers have made since the page loaded. None of them carries image data.

No network requests recorded yet.

    Codec files are WebAssembly decoders. They are downloaded to your device once and then run inside your browser.

    Airplane-mode challenge

    Do not take our word for it — cut the connection and watch the converter keep working.

    1. Load this page once, then switch on airplane mode or turn off Wi-Fi.
    2. Drop an image into the converter and convert it as usual.
    3. The conversion finishes and the download works. A converter that uploaded your files could not do that.

    Check it in your browser's developer tools

    1. Press F12 (⌥⌘I on macOS) and open the Network tab, then reload the page.
    2. Convert an image and watch the requests that appear.
    3. You will see our scripts and codec files being downloaded, and no request that uploads your image — check the size and payload column of every entry.

    Background caching by the service worker also shows up in DevTools: it downloads our app files for offline use. It never uploads anything.
