JPG to WebP Converter

WebP uses more modern compression than JPG, so at the same visual quality a WebP photo is typically around a quarter to a third smaller. The exact saving depends on the source:

• High-quality camera or phone JPGs (large files, light compression) usually shrink the most.
• Already compressed JPGs, such as images downloaded from social media, may shrink only a little. Re-encoding cannot remove information that is already gone, and in rare cases the WebP ends up about the same size.
• Oversized photos benefit most from resizing. A 12 megapixel photo shown 1200 pixels wide is wasting far more bytes than the format choice.

This converter writes WebP at a high quality level (about 90) so photos look the same as the originals. If you need a smaller file than that, follow up with Compress Image, and use Resize Image before converting when the photo is bigger than its display size.

WebP is supported by every current browser, including Safari since 2020, and by WordPress, Shopify, Squarespace, Wix and most other platforms. Android and Windows open WebP natively, and recent versions of macOS Preview and Photoshop do too.

JPG is still the better choice for files that leave the web: email attachments, print orders, government or job portals and older desktop software may reject or fail to preview WebP. A good workflow is to keep your original JPGs as masters and publish WebP copies. Lossy formats lose a little each time they are re-encoded, so always convert from the original JPG rather than from a WebP you converted earlier.

The WebP keeps the photo's dimensions and colours. Camera EXIF data, including GPS location, is not copied into the new file, which is often what you want for public images.

The format is only one part of a fast image. For photos going onto a website, this order gives the smallest files with the least effort:

• 1. Crop to the framing you want with Crop Image. Cropped-away pixels are free savings.
• 2. Resize to about the largest width the photo is displayed at, or twice that for sharp results on high-density screens. Resize Image handles this.
• 3. Convert to WebP here, 10 photos at a time.
• 4. Check the size. If a photo is still heavier than your budget, for example 200 KB for a hero image, run it through Compress Image.
• 5. Upload with a descriptive file name and alt text.

Keep the untouched JPG originals in a separate folder. Whenever you need a new size or a new format later, start from the original rather than from a WebP you already made. Photos taken on an iPhone in HEIC format can be turned into JPG first with the HEIC Converter.
