JPG to WebP Conversion Tips — Get the Best Results
Follow these best practices when converting JPG to WebP to get the highest quality output at the smallest possible file size.
Use 80–90% Quality for Most JPG Photos
When converting JPG to WebP, a quality setting of 80–90% produces visually indistinguishable results from the original JPG while reducing file size by 25–35%. Use the Before/After slider to verify before downloading.
Keep JPG for Email — Use WebP for Web
Converting JPG to WebP is ideal for websites, blogs, and web apps. However, keep JPG format for email newsletters and print materials — email clients have poor WebP support and most print workflows require JPG or PDF.
Use the HTML Picture Element After Converting
After converting JPG to WebP, serve both formats using the HTML <picture> element for maximum compatibility. This lets modern browsers load WebP while older browsers automatically fall back to the original JPG.
Convert JPG to WebP Before Uploading to CMS
Always convert JPG to WebP before uploading to WordPress, Shopify, or any CMS. Converting before upload ensures the smallest file is stored and served — some CMS platforms do not convert images automatically.
Always Keep the Original JPG File
Never delete the original JPG after converting to WebP. The JPG will still be needed for email, print, and any platform that does not support WebP. Keep both versions organized in your file library.
Resize While Converting JPG to WebP
Use our JPG to WebP converter's resize feature to reduce image dimensions at the same time as converting. A 4000×3000px JPG resized to 1920px max width and converted to WebP can be 90% smaller than the original.
Convert JPG to WebP at the Right Size for Every Platform
After converting JPG to WebP, these are the recommended dimensions for each platform. Use our converter's resize feature to set the correct output size in one step.
Resize + Convert in one step: Our JPG to WebP converter lets you set a maximum output width before converting. Select Max 1920px, 1280px, or 800px in the options panel, then click Convert JPG to WebP. Your image is resized and converted to WebP in a single operation — no separate resize tool needed.
