Download a Sample WebP File (Any Size)

Generate and download a sample WebP Image file at any exact size — free, in-browser, no signup.

WebP is Google's modern web image format — better compression than JPEG and PNG at equivalent quality, and now natively supported in every major browser and OS since 2020. If you are building an image CDN, testing a WebP conversion pipeline, or checking how your application handles a format it may not have encountered before, you need a genuinely valid WebP, not a renamed JPEG. Generate one here at any exact even-byte size, entirely in your browser.

Common WebP Image test sizes

Each preset is generated in your browser at exactly that many bytes (decimal: 1 MB = 1,000,000 bytes). For any other size, use the generator above.

100 KB sample WebP Image file

A 100 KB WebP is a well-optimized product image or a high-quality web graphic — the format and size you would serve from a modern image CDN. Testing your CDN's WebP handling, your browser's fallback logic, or your image optimization API at this size confirms the pipeline works correctly before you point it at production assets. Valid WebP container, generated in your browser.

1 MB sample WebP Image file

A 1 MB WebP is a high-resolution hero image or an unoptimized conversion from a large JPEG. At this size, the quality difference between WebP and JPEG at equivalent visual fidelity becomes measurable — and the correct functioning of your image CDN's format negotiation becomes verifiable. Valid WebP, opens in all modern browsers, generated in your browser.

5 MB sample WebP Image file

Five megabytes is an unusually large WebP — the size of an uncompressed or lossless high-resolution image stored in the format. Use it to test edge image transformation services, validate WebP-specific size limits in upload systems, and stress-test any code that processes the WebP RIFF container at scale. Valid WebP container, even byte size, generated in your browser.

Common use cases for WebP Image test files

  • Testing modern image CDN pipelines and WebP-specific processing branches
  • Validating browser WebP support detection and fallback logic
  • Checking image optimization APIs that accept or output WebP
  • Stress-testing edge image transformation services with a valid modern format

Frequently asked questions

Will this WebP open in Chrome, Safari, Edge, and macOS Preview?

Yes. WebP has had native support in Chrome since 2010, Edge since 2018, and Safari since 2020. The generated file uses the standard RIFF-based WebP container, which all of these applications handle natively.

Can I use this to test an image CDN processing pipeline?

Yes. Services like Cloudflare Images, Imgix, and AWS CloudFront support WebP transformation. A valid sample WebP at a known size lets you verify your CDN pipeline — accept headers, origin fetching, cache key behavior — before pointing it at production assets.

Why do the size options only show even byte counts?

The WebP RIFF container specification requires the file payload to be an even number of bytes. All MB and KB sizes are even numbers, so any round-number size you request is automatically compliant. The generator handles the constraint transparently.
