WebP: The Image Format You Should Probably Be Using

If you've ever saved an image from the web and noticed it downloaded as a .webp file instead of .jpg or .png, you've already encountered WebP. Developed by Google and released in 2010, WebP has quietly become the dominant image format on the modern web.

But if you're not a web developer, WebP can be annoying. Some older apps won't open it. You can't always upload it where you need to. And converting between WebP and other formats feels like it should be simpler than it is.

This guide covers everything: what WebP actually is, why it's better than JPG and PNG for most use cases, and how to convert to and from it.

What Is WebP?

WebP is an image format designed specifically for the web. It supports:

• Lossy compression (like JPG) — reduces file size by discarding some detail
• Lossless compression (like PNG) — preserves every pixel perfectly
• Transparency (like PNG) — full alpha channel support
• Animation (like GIF) — animated images with millions of colors

In other words, WebP is a single format that can replace JPG, PNG, and GIF in most scenarios — and it does each job in a smaller file.

WebP vs JPG vs PNG: The Numbers

Here's what the actual file size difference looks like:

These aren't cherry-picked examples — Google's own studies show WebP provides 25-35% smaller files than JPG at equivalent quality, and 26% smaller files than PNG for lossless compression.

Why WebP Is Better

Smaller Files, Same Quality

The core advantage is straightforward: WebP images are significantly smaller than the equivalent JPG or PNG without any visible difference in quality. For websites, this means:

• Faster page loads — less data to download
• Lower bandwidth costs — especially for high-traffic sites
• Better Core Web Vitals — Google uses page speed as a ranking factor
• Less storage — relevant if you host thousands of images

Transparency Without the Bloat

PNG is the go-to format when you need transparency (like logos on a transparent background). But PNG files with transparency are often very large. WebP supports full transparency at a fraction of the file size — typically 60% smaller than the equivalent PNG.

One Format to Rule Them All

Before WebP, you needed:

• JPG for photos
• PNG for graphics with transparency
• GIF for animations

WebP handles all three, which simplifies your workflow and your website's code.

When NOT to Use WebP

WebP isn't perfect for every situation:

• Print design — Use TIFF or high-quality JPG. WebP is web-focused.
• Professional photography archives — RAW or TIFF preserves more editing flexibility.
• Email newsletters — Some older email clients don't render WebP. Stick with JPG/PNG for emails.
• Uploading to platforms that don't accept it — Some forums, older CMS platforms, and certain social media upload forms still require JPG or PNG.
• When you need maximum compatibility — JPG and PNG are still more universally supported in desktop software.

Browser & Platform Support in 2026

WebP support is now excellent:

The bottom line: In 2026, over 97% of web users have a browser that supports WebP. The days of needing JPG fallbacks are largely over.

How to Convert Images to WebP

If you want to optimize your images for the web, converting to WebP is one of the easiest wins.

Convert JPG to WebP

1. Go to the JPEG to WebP Converter
2. Upload your JPG file
3. Download the WebP version

You'll typically see a 25-35% reduction in file size with no visible quality difference.

Convert PNG to WebP

1. Go to the PNG to WebP Converter
2. Upload your PNG file
3. Download the WebP version

This is especially impactful for PNGs with transparency — expect 40-60% smaller files.

How to Convert WebP to Other Formats

Downloaded a WebP file and need it in a more common format? Here's how.

WebP to JPG

Use the WebP to JPEG Converter. Best for photos and images where you don't need transparency. The resulting JPG will work in any app or upload form.

WebP to PNG

Use the WebP to PNG Converter. Choose this when you need to preserve transparency or want lossless quality.

WebP to GIF

Use the WebP to GIF Converter if you need the animated version in GIF format for older platforms.

Compressing WebP Files

WebP files are already smaller than JPG/PNG, but you can optimize them further with the WebP Compressor. This is useful when:

• You need to hit a specific file size target
• You're optimizing hundreds of images for a website
• You want to squeeze out every last byte of performance

WebP for Website Owners

If you run a website, switching to WebP is one of the highest-impact, lowest-effort optimizations you can make.

Quick Wins

1. Convert your existing images. Take your JPGs and PNGs and run them through the JPEG to WebP or PNG to WebP converter. Upload the WebP versions to your site.

2. Use WebP for new uploads. Many CMS platforms (WordPress, Shopify, Squarespace) now auto-convert to WebP. Check your platform's settings.

3. Compress what you've got. Already using WebP? Run your images through the WebP Compressor for additional savings.

The HTML Picture Element

For maximum compatibility, you can serve WebP to supported browsers and fall back to JPG for the rest:

<picture>
  <source srcset="image.webp" type="image/webp">
  <img src="image.jpg" alt="Description">
</picture>

Though in 2026, with 97%+ browser support, many sites skip the fallback entirely.

Common Questions

"Can I edit WebP files in Photoshop?"

Yes. Adobe Photoshop CC 2022 and later can open and save WebP natively. For older versions, Google offers a free WebP plugin.

"Does converting to WebP lose quality?"

Lossy WebP (the default for photos) does discard some data, similar to JPG. At recommended quality settings (75-85), the loss is not visible to the human eye. Lossless WebP preserves every pixel, like PNG.

"Why can't I upload WebP to [platform]?"

Some platforms still require JPG or PNG. In these cases, convert your WebP to JPG or PNG first using the converters above. This is becoming less common as platforms update their upload handling.

"Is WebP the same as AVIF?"

No. AVIF is a newer format (based on AV1 video codec) that offers even better compression than WebP in some cases. However, AVIF support is still catching up, encoding is slower, and WebP remains the more practical choice for most use cases in 2026.

Bottom Line

WebP is the best general-purpose image format for the web in 2026:

• 30% smaller than JPG for photos
• 60% smaller than PNG for transparent graphics
• 35% smaller than GIF for animations
• Supported by 97%+ of browsers

If you're sharing images online or building a website, WebP should be your default. For everything else — print, archival, legacy platforms — JPG and PNG still have their place.
