    Free Bulk PNG and JPG to WebP Converter

    This free online tool converts PNG and JPG (JPEG) images into the modern WebP format in a few seconds. You can convert a single image or a whole batch of up to 50 images at once, then download each file separately or all of them together in one ZIP file. There is no sign-up, no watermark and no limit on how many times you use it.

    Everything happens inside your own web browser. Your photos are never uploaded to our server, so the tool is fast, private and safe to use with personal or client images. Converted files are cleared automatically after 1 hour, or as soon as you close the page.

    How to use this converter

    1. Drag and drop your PNG or JPG images into the box above, or click Choose images.
    2. Pick a quality level with the slider. 80% is a good balance for most photos.
    3. Wait a moment while each image is converted. You will see the old size, the new size and how much space you saved.
    4. Click Download next to any image, or Download all (ZIP) to save every file at once.

    Tip: use 90–100% quality for images with small text, logos or sharp lines. Use 60–75% for large background photos where file size matters most.

    What is WebP?

    WebP is an image format created by Google for the web. It uses smarter compression than JPG and PNG, so images look almost the same but take up much less space. WebP supports both photos and graphics, keeps transparent backgrounds, and works in every modern browser.

    Benefits of converting images to WebP

    • Much smaller files: WebP images are usually 25–35% smaller than JPG and often 50–80% smaller than PNG at similar visual quality.
    • Faster website loading: Smaller images mean pages open faster, especially on mobile data.
    • Better SEO and Core Web Vitals: Page speed is a Google ranking factor. Lighter images help improve Largest Contentful Paint (LCP) scores.
    • Lower hosting and bandwidth use: Smaller files use less storage and less monthly bandwidth on your server or CDN.
    • Keeps transparency: Unlike JPG, WebP keeps the transparent background of your PNG logos and icons.
    • Better user experience: Visitors see your photos sooner and are less likely to leave a slow page.
    • Works with WordPress: WordPress, Shopify and most website builders accept WebP uploads.

    Pros and cons of WebP

    Pros

    • Smaller file size than JPG and PNG at similar quality
    • Supports transparency (like PNG) and photos (like JPG) in one format
    • Supported by Chrome, Edge, Firefox, Safari, Opera and all modern mobile browsers
    • Recommended by Google PageSpeed Insights (“Serve images in next-gen formats”)
    • Also supports animation, so it can replace large GIF files

    Cons

    • Some older software, very old browsers and a few photo editors cannot open WebP files
    • Not ideal for printing or professional photo editing — keep your original JPG or PNG for that
    • Lossy WebP removes some detail, so very low quality settings can blur fine text
    • Some email clients and social media apps may convert or not display WebP images
    • Already heavily compressed images may not get smaller, and can sometimes get slightly bigger
