Does this image converter upload my PNG files?

No. The conversion runs locally in your browser, so your PNG files stay on your device while WebP output is generated.

Can I convert multiple PNG files to WebP at once?

Yes. You can add multiple PNG files, convert them as a batch, and download the finished WebP files individually or in one ZIP archive.

Will transparent PNG backgrounds stay transparent in WebP?

Yes. WebP supports transparency, so transparent PNG assets can usually be converted without adding a background color.

What quality setting should I use for PNG to WebP conversion?

A quality setting between 75 and 90 is a practical starting point for most screenshots, interface graphics, and web assets, but you can adjust it based on the level of detail you need.

Why use WebP instead of PNG for web delivery?

WebP often produces smaller files than PNG while maintaining strong visual quality, which can make pages load faster and reduce bandwidth usage.

Three Reasons to Convert PNG to WebP

The format switch pays off faster than most teams expect.

File Size

Cut Page Weight Without Redesigning

WebP is typically 25–35% smaller than PNG at comparable quality, so pages load faster without changing a single layout.

Transparency

Alpha Channels Carry Over Cleanly

WebP supports transparency, so icons, cutouts, and UI overlays convert without gaining a white background or needing a re-export.

Workflow

No Software, No Upload, No Account

Drop files in, export WebP, and get back to shipping. The entire conversion runs locally in your browser — nothing leaves your device.

How to Convert PNG to WebP

Three steps from PNG file to production-ready WebP asset.

Upload Your PNG Files

Add one file or a full batch — UI exports, product cutouts, screenshots, and transparent assets all work.

Set the Quality Level

Move the slider to balance file size and detail. A setting of 75–90 works well for most web graphics.

Download as WebP or ZIP

Conversion runs locally in your browser. Download each file individually or grab the full batch as a ZIP archive.

What This PNG to WebP Converter Does

Everything you need to go from PNG to WebP — without leaving the browser.

Batch PNG Upload

Add one file or a full batch in a single drop. The converter queues them all and processes each one in sequence.

Adjustable Quality

Set compression level per session with the quality slider. Higher keeps detail; lower cuts file size further.

Fully Local Processing

Files never leave your device. Conversion runs entirely in the browser using the Canvas API — nothing is uploaded.

Transparency Preserved

PNG alpha channels carry over to WebP automatically. Icons, UI overlays, and product cutouts stay transparent.

ZIP Download for Batches

When conversion finishes, download each WebP file individually or export the full batch as a single ZIP archive.
