Why Websites Use WebP (and Why That Creates Problems for You)
Built for Speed
Google developed WebP in 2010 as a modern image format designed specifically for the web. The goal was simple: deliver the same visual quality as JPEG but at 25-35% smaller file sizes. Smaller images mean faster page loads, less bandwidth usage, and better Core Web Vitals scores that Google rewards with higher search rankings.
The Save-As Surprise
The adoption was gradual at first, but today the vast majority of major websites serve images in WebP. When you right-click an image and save it from a news site, blog, e-commerce store, or social media platform, you often end up with a .webp file instead of the expected .jpg. The image looked fine in your browser, but now it will not open in your image editor, your email client rejects it, and your printer software does not recognize it.
JPG Restores Universal Access
The browser understands WebP because Google built that support directly into Chrome (and other browsers followed). But that does not help when you need the image outside the browser. Converting to JPG gives you a file that every application, service, and device in existence handles without question.
WebP vs JPEG: Technical Comparison
| Feature | WebP (Google) | JPEG (Universal) |
|---|---|---|
| File Size | 25-35% smaller than JPEG at same quality | Larger files, but universally accepted |
| Compression Type | Both lossy and lossless modes | Lossy only (with quality setting) |
| Transparency | Supported (alpha channel) | Not supported |
| Animation | Supported (animated WebP) | Not supported |
| Software Support | Browsers yes, many apps no | Everything supports JPEG |
| Year Created | 2010 (relatively new) | 1992 (three decades of support) |
Applications That Still Cannot Open WebP
Image Editors
Photoshop before version 23.2 (2022), older GIMP versions, Paint.NET without plugins, IrfanView without plugins, many batch processing tools.
Office Software
Microsoft Word, Excel, PowerPoint (older versions), Google Docs image insert (sometimes problematic), LibreOffice (varies by version).
Email Clients
Outlook desktop, Thunderbird, corporate email systems. Many strip WebP attachments or display them as unknown file types.
Social Media Upload
Some platforms accept WebP uploads, but many older systems, forums, classified ad sites, and CMS platforms still reject the format.
Print Services
Photo printing kiosks, online print shops (Vistaprint, Shutterfly, etc.), and most commercial printers do not accept WebP files.
Legacy Systems
Medical imaging software, government portals, banking upload forms, insurance claim systems, and enterprise applications built before WebP adoption.
How WebP Compression Works
VP8 Codec Foundation
WebP uses VP8 video codec technology for lossy compression (the same codec used in WebM video) and a custom algorithm for lossless compression. The lossy mode achieves smaller files than JPEG by using more advanced prediction methods: instead of processing 8x8 pixel blocks like JPEG, WebP predicts pixel values based on already-decoded neighboring blocks, then only stores the differences.
Prediction-Based Efficiency
This prediction-based approach is why WebP consistently beats JPEG on file size. But it also means WebP requires more processing power to decode, which is negligible on modern hardware but contributes to why adoption in older software has been slow. The encoding algorithm is more complex, which means fewer applications bothered to implement it when JPEG worked fine for their purposes.
The Conversion Process
When you convert WebP to JPG, the VP8-compressed pixel data is decoded into raw pixels, then re-encoded using JPEG's DCT-based compression. At high quality settings (92-95%), the visual result is indistinguishable from the WebP original. The file will be somewhat larger (since JPEG compression is less efficient), but it gains universal compatibility as a tradeoff.
Frequently Asked Questions
Why is the JPG file larger than the original WebP?
WebP uses more advanced compression than JPEG, producing smaller files at the same quality. When you convert, the JPEG encoder is less efficient at compressing the same pixel data. A 200KB WebP may become a 350-500KB JPEG. This is expected and is the tradeoff for universal compatibility.
Can I convert animated WebP to JPG?
JPEG does not support animation. If your WebP file is animated (like an animated GIF replacement), the converter will extract and convert the first frame as a static JPG image. For animated content, consider converting to GIF or keeping the WebP format.
How do I stop Chrome from saving images as WebP?
Chrome saves images in whatever format the website serves. If the site uses WebP (most do now for performance), that is what you get. Some browser extensions can force JPEG downloads, but the simplest approach is to save the WebP file and convert it here. Alternatively, right-clicking and choosing "Copy Image" then pasting into Paint or another editor sometimes produces a PNG copy.
Is there any quality difference between WebP and JPG at the same file size?
At the same file size, WebP generally looks slightly better than JPEG because its compression algorithm is more efficient. However, at the quality levels used for web delivery (75-85% in WebP, 85-92% in JPEG), both formats look excellent and the difference is only detectable through pixel-level comparison tools, not by human eyes in normal viewing.
