How to Compress Images to WebP

Three simple steps: upload images, adjust quality if needed, download the result. Everything happens in the browser, no files sent to the server.

Step 1. Upload files

Drag and drop images (JPEG, PNG) into the workspace or click to select files from your device.

Step 2. Adjust compression

If needed, adjust the quality slider to find the balance between file size and image clarity.

Step 3. Save the result

Download optimized files in WebP format. Conversion happens locally in your browser; files are never uploaded.

Why Use WebP?

Google's WebP format offers smaller size at the same visual quality — sites load faster.

Fast loading

Lighter pages load faster on mobile and slow connections. Important for SEO and conversion.

Lossless quality

Supports both lossy and lossless compression. You can tune the size vs. quality balance for your project.

Browser support

All modern browsers support WebP. For older ones you can keep a JPG/PNG fallback.

All About WebP Format and Image Optimization

A brief overview of what WebP is, why sites need it, and why our converter is safe for your files.

What is WebP and Why It's the Standard

WebP is a modern image format from Google with excellent compression and no visible quality loss.

WebP images are 25–35% smaller than JPEG and 26% smaller than PNG (including transparency). Switching to WebP is the fastest way to speed up any site.

How WebP Affects SEO and Sales

Google (Core Web Vitals) heavily penalizes slow sites. A landing page over 3 seconds loses up to 50% of visitors. Heavy images are the main cause. WebP addresses this directly:

  • Higher conversion: fast loading reduces bounce; users comfortably view the site on mobile — more leads.
  • Hosting savings: smaller images mean less disk and bandwidth, especially for high-traffic projects.
  • Green PageSpeed: replacing JPEG and PNG with WebP is Google's first recommendation in speed audits.

Security and Privacy

The converter runs entirely in the browser. Files are never sent or stored on servers. Safe to convert corporate materials, document scans, or design assets with no leakage risk.

Frequently Asked Questions

Short answers on browser support, transparency, quality, and conversion speed.

Do older browsers support WebP?

All modern browsers support WebP. For older devices developers use the <picture> tag with a JPEG or PNG fallback.

Does WebP support transparency?

Yes. WebP supports an alpha channel and compresses better than PNG at the same transparency quality.

How long does conversion take?

A fraction of a second. All processing is in your browser, with no upload to the server.

Is quality lost when converting?

It depends on settings. With lossless compression, quality matches the source. With lossy compression you can set the quality level — 80–85% is usually visually indistinguishable at a smaller size.

What formats can be converted to WebP?

JPEG and PNG. The converter accepts these and outputs WebP. Screenshots, camera photos, social images, and editor exports work — upload, choose quality, download with no sign-up.

Is there a limit on file size or count?

Limits are only due to browser memory. Very large images (tens of megapixels) may take longer. Converting one at a time or in small batches is recommended.
