WebP Converter

What Is WebP?

WebP is an image format developed by Google. It uses modern compression techniques that produce smaller file sizes compared to JPG and PNG at equivalent visual quality.

WebP supports:

• Lossy compression (like JPG) — smaller files, slight quality reduction
• Lossless compression (like PNG) — exact pixel reproduction
• Transparency (like PNG) — transparent backgrounds are preserved
• Animation (like GIF) — animated images are supported

The format is supported by all modern browsers including Chrome, Firefox, Edge, Safari (version 14 and later), and Opera.

WebP vs JPG, PNG, and GIF

File size comparison:

• WebP vs JPG: WebP is typically 25–35% smaller at the same quality level
• WebP vs PNG: WebP lossless is around 25% smaller than PNG
• WebP vs GIF: WebP produces significantly smaller animated files than GIF

Use Cases

Optimizing images for a website

WebP files load faster than JPG or PNG files because they are smaller. Converting your site’s images to WebP before uploading them to your CMS reduces page weight, which can improve load times.

Reducing image file sizes before uploading

If you need to stay within a file size limit for a form, email, or platform, converting from PNG or BMP to WebP is a quick way to reduce the file size without visibly degrading the image.

Preparing images for Google PageSpeed or Core Web Vitals

Google’s PageSpeed Insights tool frequently recommends serving images in WebP or AVIF format. Converting existing JPG or PNG images to WebP is the most direct way to address that recommendation.

Converting screenshots or graphics

PNG screenshots and graphics can be large. Converting them to WebP lossless produces a smaller file with no visual change — useful when sharing or archiving screen captures.

Replacing GIF animations

Animated GIFs are often large files. Converting an animated GIF to WebP produces a much smaller file that loops the same way in all modern browsers.

Helpful Tips

Keep your original files.

The conversion process is one-way — you cannot perfectly recover a JPG from its WebP version if lossy compression was applied. Always keep the original image file before converting.

WebP is not universally supported everywhere.

Modern browsers all support WebP, but some older email clients, image editors, and desktop applications may not open WebP files. If you need broad compatibility outside a browser, use JPG or PNG instead.

PNG to WebP gives the largest size reduction.

PNG files are losslessly compressed but tend to be large. Converting PNG to WebP lossless typically reduces the file size by around 25% with no quality loss. For photos saved as PNG, switching to WebP lossy gives an even larger reduction.

Check the result before replacing production images.

Download the converted file and inspect it before replacing images on a live website. For product photos or images where visual quality is critical, verify that the compression level meets your standards.

Large or complex images may take a moment to process.

The tool runs in your browser using your device’s processing power. Very large images (close to the 10 MB limit) may take a few extra seconds to convert, particularly on older devices.
