Why Convert JPG to WebP?
Converting JPG to WebP is one of the fastest wins you can make for your website's performance. WebP is a modern image format developed by Google that delivers significantly smaller file sizes — typically 60–80% smaller than JPG — with the same visual quality.
If you run a Shopify store, a blog, or any website with images, switching to WebP directly impacts your Google Core Web Vitals score, your page load time, and ultimately your search rankings.
The good news: converting JPG to WebP takes seconds with the right tool — and it's completely free.
JPG vs WebP: File Size Comparison
Before we walk through the conversion process, here's what the file size difference actually looks like in practice:
- Product image (2400×2400px): JPG 1.8 MB → WebP 210 KB (-88%)
- Hero banner (1920×1080px): JPG 4.2 MB → WebP 480 KB (-89%)
- Thumbnail (600×600px): JPG 380 KB → WebP 52 KB (-86%)
- Blog header (1200×630px): JPG 920 KB → WebP 130 KB (-86%)

- 1Go to the Image Converter tool and click 'Upload Image'
- 2Select your JPG, JPEG, or PNG file (up to 5 MB on free tier)
- 3Choose WebP as the output format, set quality (80 is the sweet spot), click Convert
- 4Download your WebP file — done in seconds
Quality 75–85 is the sweet spot for WebP. Below 75 you'll see compression artifacts. Above 85 you lose most of the file-size benefit.
How to Bulk Convert JPG to WebP (Hundreds at Once)
For e-commerce stores with large product catalogs, converting images one by one isn't realistic. BatchSet's Bulk Converter lets you process hundreds of JPG images to WebP in a single batch.
You can either upload files directly (up to 500 at once on Pro), or use the Excel batch mode: paste your image URLs into a spreadsheet, upload it, and BatchSet converts and packages everything into a ZIP file.
When Should You NOT Use WebP?
WebP is the right choice for almost all web use cases. However, there are a few situations where you might keep JPG or PNG:
- Print production — WebP is web-only; use TIFF or high-quality JPG for print
- Email clients — some older email clients don't render WebP; use JPG for email
- Software with limited format support — some tools don't read WebP natively
- Transparent backgrounds — use WebP (it supports transparency), but PNG is also fine
WebP Browser Support in 2026
WebP is supported by 97%+ of browsers globally as of 2026. This includes Chrome, Firefox, Safari (since version 14), Edge, Opera, and all major mobile browsers. You don't need to worry about fallbacks for modern websites.
