Why Resize WebP Images?
WebP is the modern image format developed by Google, supported by all major browsers since 2020. It produces files 25–35% smaller than JPEG at the same visual quality, and 30–50% smaller than PNG for images with transparency. If your CMS, Next.js project, or CDN delivers WebP assets, you need to resize them to exact dimensions — and keep them in WebP format.
This tool resizes WebP files and outputs them back as WebP. You keep the compression advantage of the format without converting to a heavier JPG or PNG in the middle of your workflow.
Common WebP Resize Use Cases
Next.js and React projects
Next.js Image component serves WebP automatically, but source assets must be the correct dimensions. Resize your WebP images to match the layout breakpoints defined in your component.
CMS and WordPress uploads
WordPress 5.8+ generates WebP variants from uploads. Uploading a pre-sized WebP gives you control over the exact dimensions and avoids server-side resampling quality loss.
Shopify and e-commerce
Shopify serves WebP automatically via their CDN. Pre-resizing product images to 2048×2048px as WebP before uploading ensures maximum quality at minimum file size.
Social media and Open Graph
Twitter, LinkedIn, and Facebook read Open Graph images at 1200×630px. Resize WebP images to these dimensions for social previews that load fast and display sharply.

Frequently Asked Questions
Does the output stay in WebP format after resizing?▼
Yes. When you upload a WebP file, the tool outputs a resized WebP. The format is preserved, so you keep the compression benefits.
Is WebP supported in all browsers?▼
Yes. WebP is supported in Chrome (since 2014), Firefox (since 2019), Safari (since 2020), and Edge (since 2018). As of 2024, browser support is effectively 95%+ globally. It is safe to use WebP for all public-facing web images.
How do I resize a WebP for a WordPress featured image?▼
WordPress typically uses featured images at 1200×628px for social sharing and 1200×900px for full-width layouts. Resize your WebP to match your theme's recommended dimensions. WordPress 5.8+ will serve your pre-sized WebP without re-encoding it.
Can I resize a WebP with transparency?▼
Yes. The Canvas API supports transparent WebP (lossless WebP). Upload your transparent WebP, resize it, and download — transparency is preserved in the output.
Should I use WebP or AVIF for web images?▼
WebP offers 25–35% smaller files than JPG with near-universal browser support. AVIF is 40–50% smaller than JPG but has more limited browser support (Chrome 85+, Firefox 93+, Safari 16.4+). For maximum compatibility, WebP is the safer choice today.
Are my WebP files uploaded to a server?▼
No. All resizing happens entirely in your browser using the Canvas API. Your files are never sent to any server.
