Target format

"Auto" re-encodes in the original format; BMP, GIF and ICO have no modern counterpart and are normalized to PNG.

Quality

Applies to JPG, WebP and AVIF output. Around 80% is the sweet spot between size and fidelity.

PNG is lossless and ignores the quality slider — the resulting file size is determined by the image content itself.

New settings apply to the whole batch only after you click here.

Every conversion happens inside your browser. Images are never uploaded to any server.

Why move PNG screenshots and graphics to WebP

PNG is lossless, so a screenshot of a dashboard or a product mockup can easily reach 1–3 MB. WebP keeps the same visible quality — including the alpha channel — in a fraction of the bytes. In practice PNG-to-WebP is the single cheapest page-weight win for sites full of UI images.

Quality 80–85 is the sweet spot for graphics and screenshots; text edges stay crisp while the file drops sharply. For photographic PNGs, quality 75 is usually enough and the savings get even larger.

One thing to check before publishing: WebP is supported by every browser released since 2014, but some older desktop software (a few CMS uploaders, office suites and email clients) still refuses it. If that applies to you, keep a PNG or JPEG fallback.

How to convert PNG to WebP

Add your PNG files

Drag files or a folder into the workspace, or paste from the clipboard. The target format is already set to WebP.

Set the quality

80 is a safe default for screenshots and UI graphics; lower it to 70–75 for large photos if size matters more than fine detail.

Download

Each file keeps its base name and gets a .webp extension. Download one by one or as a single ZIP.

Questions about this task

Is transparency preserved when converting PNG to WebP?

Yes. WebP supports an alpha channel, so logos, cut-out product shots and UI overlays keep their transparent areas. JPEG would flatten them onto white.

How much smaller will my files get?

Graphics and screenshots typically drop 30–60% at quality 80. Photographic PNGs often shrink even more, because WebP can use lossy encoding where PNG cannot.

Can old browsers open the WebP files?

Any browser from 2014 onwards reads WebP, including Safari 14+. The remaining risk is older desktop apps and email clients. If you cannot ship a fallback, export PNG or JPEG instead.
