With the growing popularity of the WebP image format, many users now find themselves dealing with these modern image files more frequently. Developed by Google, WebP is designed to provide superior compression with minimal loss in image quality, making it an excellent choice for web developers and digital content creators. However, native support for WebP files is still inconsistent across various platforms, making the need for efficient and user-friendly online WebP viewers more important than ever.
Fortunately, there are several online tools available for viewing WebP files easily without downloading any software. In this review, we’ll break down the best online WebP viewer tools currently available, so you can choose the one that best fits your workflow and needs.
1. Google Photos
Google Photos is a surprisingly reliable option for viewing WebP files online. Since WebP is a Google-driven format, it’s no surprise that Google’s first-party photo management software handles the format well.
- Pros: High reliability, seamless sync with your Google account, mobile-ready.
- Cons: Limited editing capabilities for WebP, privacy considerations for uploading images online.
If you already have a Google account, uploading and viewing WebP images can be done within seconds. While it doesn’t have specialized WebP features, it supports drag-and-drop uploads and folder organization, making it practical for general use.
2. Photopea
Photopea is a free, browser-based photo editor that also offers robust support for WebP files. More than just a viewer, Photopea provides Photoshop-like editing tools in a sleek, fast web interface.
- Pros: Powerful editing tools, no downloads required, supports layers and advanced file formats.

Photopea is ideal for designers or photographers who need more than just a viewing tool. It works entirely online, without installing any software, and supports several formats including WebP, PSD, JPG, and PNG.

3. AConvert.com
AConvert.com is primarily known as a file conversion platform, but it also features a quick viewing system for WebP files. Simply upload your file, and once the upload is successful, you can preview the file directly.
- Pros: Fast uploads, supports multiple file types, allows easy format conversion.
- Cons: Ad-heavy interface, not optimized for high-resolution images.
If you also need the ability to convert WebP files to formats like JPG, PNG, or BMP, AConvert.com offers one of the easiest interfaces to do so without sacrificing image quality. It’s particularly useful for quick one-off tasks.
