More about converting JPG to WebP
WebP can reduce the size of photographic images while maintaining similar visible quality, making it useful for websites, product pages, portfolios, and other image-heavy projects. Smaller image files can reduce transfer size and help pages load faster.
Upload one or more JPG files, choose the WebP quality and dimensions, and decide whether metadata should remain in the output. Start with a quality setting around 80-85 and compare the result visually before replacing production images. Keep the original JPG as a fallback when supporting older software or workflows that do not accept WebP.
When you'd use this
Reasons to convert JPG to WebP usually come down to compatibility, file-size, or specific feature requirements. Common situations:
- An app or platform only accepts WebP uploads.
- You need a feature unique to WebP (e.g. transparency, vector scaling, animation, multi-page pages, etc.) that JPG doesn't provide.
- You're optimising file size — modern formats often produce smaller files than the older format you started with.
- You need a single archival format across a project so files behave consistently in the same viewer.
How to do it in jpg.now
- Open the JPG → WebP tool on jpg.now.
- Drag your JPG file onto the drop zone, or click Select files. You can drop a whole folder of files at once.
- The output is fixed to WebP. If the format supports extra options (page size, transparency background, quality, EXIF stripping), tweak them in the right-hand panel.
- Click Convert. The job runs on our server and finishes in a few seconds for typical photos.
- Download the result. Files stay in storage for 24 hours and are then permanently deleted.
The entire flow is free for the first 10 jobs per day with no signup required. A free account doubles that quota; a premium plan removes the limit entirely.
Tips and common pitfalls
- Target 80–85% WebP quality for web images - This matches JPEG 90% quality at roughly 30% smaller file size.
- Use WebP for hero images, product photos, and any image loaded above the fold - These have the greatest impact on page load speed.
- If you need transparency, start from a PNG source rather than JPG, since the JPG background colour will be preserved in the WebP.
- Run a quick visual comparison at 80% before deploying - Open the original JPG and the WebP side-by-side in a browser at 1:1 zoom to confirm quality is acceptable.
- For e-commerce sites, converting all product images from JPG to WebP typically reduces total page weight by 20–40% with zero visible quality difference.
