WebP Converter
Upload your WebP file below and choose the output format. The URL updates instantly as you select, and conversion happens right in your browser — your files stay private.
WebP is an image format developed by Google and released in 2010. It delivers 25 to 35% better compression than JPG and 20 to 30% better than PNG at similar visual quality. It supports transparency like PNG, animation like GIF, and both lossy and lossless compression modes.
Browser support crossed 95% globally when Safari added support in 2020. Chrome, Firefox, Edge, and Opera have supported it for years. For websites, WebP is now the practical default for serving images efficiently.
The main reason to convert away from WebP is compatibility. Email clients, Windows thumbnail previews, many print services, and older design tools still don't handle WebP. Converting WebP to JPG for these workflows is a daily task. Converting JPG or PNG to WebP before uploading to a CMS, CDN, or website is equally common.
This tool handles both directions. Upload a WebP to convert to JPG or PNG for broader compatibility, or upload a JPG or PNG to convert to WebP for smaller web files.

When to Use the WebP Converter
- Converting JPG or PNG images to WebP before uploading to a website or CMS
- Improving Google PageSpeed or Core Web Vitals scores by serving smaller images
- Converting WebP to JPG or PNG for older software, email clients, or print services

- Reducing CDN bandwidth and storage costs on image-heavy platforms
- Preparing images for WordPress, Shopify, or other platforms with native WebP support
Real World Examples
Improving Core Web Vitals for a blog with 400 images
A blogger runs a food site with 400 JPG post images averaging 350KB each. Converting all to WebP at 80% quality brings the average to 220KB — a 37% reduction. Google's PageSpeed Insights score for image-heavy posts moves from the mid-60s into the low 80s. Largest Contentful Paint drops from 4.2 seconds to 2.8 seconds on a mid-range mobile connection.
Converting WebP product images for a print supplier
An e-commerce business uses a print-on-demand service for branded merchandise. Their supplier's upload portal only accepts JPG. Product photos arrive as WebP from their photographer. Converting each WebP to JPG at 95% quality takes under 2 seconds per file and produces print-quality output the portal accepts without issues.
Using WebP for a transparent promotional banner
A designer creates a campaign banner with a transparent background for placement on different colored page sections. Saving as PNG gives a 185KB file. Converting to WebP with lossless transparency gives 98KB — the same clean edges at 47% of the size. The banner loads noticeably faster on mobile without any change to the design.

WebP vs Other Formats
| Format | File Size | Transparency | Best For |
|---|---|---|---|
| WebP | Small (40-300KB typical) | Yes (full alpha) | Web images, CMS uploads, modern browsers |
| JPG | Small (50-500KB typical) | No | Photos, email, print, legacy software |
| PNG | Large (500KB-5MB typical) | Yes (full alpha) | Lossless quality, logos, UI graphics |
| AVIF | Smaller than WebP | Yes | High-traffic pages, next-gen compression |
Tips for Best Results
- When converting PNG to WebP, try lossless mode first. You get a smaller file with zero quality loss. Lossy at 85% gives a further reduction but introduces slight compression.
- For photos, WebP lossy at 80 to 85% quality is the sweet spot. Most viewers can't distinguish it from the original JPG at the same display size.
- WordPress supports WebP natively from version 5.8. Shopify serves WebP automatically. Neither requires any plugin.
- For a static site, serve WebP with a JPG fallback using the HTML picture element. This covers every browser including older ones that don't support WebP.
- Don't expect WebP to be smaller than PNG for every image. Solid-color graphics and icons are sometimes similar in size. The gains are most consistent for photographs.
- WebP files don't have reliable thumbnails in Windows Explorer without installing the WebP Codec for Windows. Convert to JPG or PNG if Windows compatibility matters.

Is WebP better than JPG for all images?
For web use, WebP is better in most cases. It gives smaller files at similar quality and supports transparency. The exception is when you need maximum compatibility — older email clients, print services, legacy design software, and Windows thumbnail previews often don't handle WebP. Convert to JPG for those workflows.
Does WebP support animation?
Yes. WebP supports animation similar to GIF but with much better compression. This converter handles static images only. For animated WebP or GIF conversion, use the GIF converter at /gif-converter.
Can I use WebP for email images?
Generally no. Most email clients including Outlook and older Gmail versions don't render WebP images inline. Convert to JPG for email. The file size difference is worth addressing through other means like resizing or quality reduction.
