As web performance and user experience become increasing priorities for development teams, optimized image formats like WebP have gained significant popularity. Created by Google, WebP offers superior compression methods that can reduce image sizes drastically compared to traditional formats like JPEG and PNG, all while maintaining image quality. But while WebP is clearly a step forward in efficiency, not all tools and platforms natively support this format, making inspection and review slightly more complex—especially in collaborative team environments.
What Is WebP and Why Should You Care?
WebP is a modern image format that provides both lossless and lossy compression. It’s particularly useful for the web because it enables faster page loads and lower bandwidth usage. In an age where milliseconds can make or break user engagement, using WebP can translate to meaningful performance improvements. Here are a few benefits of using WebP:
- Reduced File Size: WebP images are typically 25–35% smaller than their JPEG or PNG counterparts.
- Transparency and Animation: WebP supports features like alpha transparency (as in PNG) and animation (as in GIF), effectively consolidating multiple functionalities into one format.
- Improved Load Speed: Smaller files lead to quicker render times, enhancing the user experience especially on mobile or slow networks.
Despite these advantages, some browsers and teams face difficulties when working with WebP files, including how to open, view, and inspect them. That’s where utilities and tools come in handy.
Essential Utilities for Viewing and Inspecting WebP Files
Whether you work in a design team, front-end dev group, or QA department, it’s crucial to have simple, fast utilities that allow you to work with WebP files without friction. Let’s look at some valuable tools and approaches that can streamline your workflow.
1. Web Browsers
Modern versions of most browsers (Chrome, Firefox, Edge, Opera) support native rendering of WebP images. You simply have to drag and drop the WebP file into a browser window or open the image via URL. This makes browsers a quick go-to option for basic viewing.
Pros: No installation required, universal accessibility.
Cons: Limited inspecting capabilities beyond what’s built into dev tools.
2. Browser Dev Tools
Once the WebP is opened in a browser, developer tools (usually accessible with F12 or right-click > Inspect) can be used to view technical information such as resolution, file size over the network, and image rendering behavior.
Great for:
- Validating image optimization effectiveness
- Checking load performance in real-time
- Inspecting CSS styling and DOM integration
3. Image Viewers with WebP Support
Many desktop image viewers now include support for WebP. Some popular choices include:
- IrfanView – Lightweight and fast with comprehensive format support
- XnView MP – Cross-platform with robust metadata views
- FastStone Image Viewer – Great for batch conversion and gallery browsing
Note: Some of these may require plugin installation to fully support WebP. Be sure to check the official documentation or FAQ sections.
4. Online WebP Viewers and Converters
If installing software seems unnecessary for your task, several online tools offer instant WebP viewing, conversion and inspection capabilities. These can be lifesavers for teams spread across different environments.
- Convertio – Drag, drop, and convert between any major formats.
- Online-Convert – Offers advanced options like adjusting compression quality and resizing.
- Ezgif – Excellent for animated WebP inspection and editing.
Security Tip: Always verify the trustworthiness of online tools before uploading sensitive or proprietary assets.
5. Software Libraries for Developers
If your team includes developers who need programmatic access to WebP files—for automation, batch inspection, or integration into CI pipelines—the following libraries might be helpful:
- libwebp (C/C++) – The official library used by Google projects.
- Pillow (Python) – With appropriate plugins, this image library can read and write WebP.
- Sharp (Node.js) – Popular in frontend/image optimization pipelines.
These libraries allow you to do everything from validating dimensions to automatically converting image formats for testing or delivery environments.
Collaboration Workflow Tips for Teams
Teams working on digital assets need an efficient and confusion-free system for reviewing WebP images. Here are some best practices to consider:
Establish Standard Tools Across the Team
When everyone uses the same tools, settings, or at least understands how to interact with WebP files, collaboration becomes much easier. Include documentation or workflows in your internal wiki or toolkit directory.
Integrate into Version Control
WebP images can be placed under version control, but it’s important to note they are binary files. Be sure to:
- Use meaningful file names and change logs
- Create thumbnails or reference renders when possible
- Keep original editable versions (PSD, AI, SVG) stored separately
Use Cloud Platforms with Previews
Cloud storage tools like Google Drive, Dropbox and OneDrive now offer limited WebP support. For collaborative scenarios, consider using:
- Figma – Supports WebP uploads and allows design annotations
- Notion – Accepts and previews uploaded images (including WebP, depending on the browser)
- Slack integrations – Share visual assets directly within conversations
Inspecting Metadata in WebP Files
Advanced users might want to inspect EXIF data, compression levels, or embedded color profiles. Unfortunately, not all tools can read metadata in WebP files, as support is still evolving. Here are some tools that do:
- ExifTool – Command-line tool that can extract and rewrite metadata
- ImageMagick – Versatile image processing tool with support for metadata extraction
- GIMP – Open-source photo editor with plugins for deeper inspection
In collaborative environments, metadata can carry important information such as image creators, timestamps, copyright, and usage guidelines—so preserving and reviewing it matters.
Future-Proofing Your WebP Workflow
As browser support and tooling around WebP improve, teams should periodically revisit their workflows to ensure they’re using the most efficient tools. Setting up a biannual audit of tooling can help ensure your team continues to leverage the full power of WebP without any bottlenecks.
Here are some quick checklist items to future-proof your process:
- Ensure all team members have access to WebP-compatible tools
- Add automated validations for image formats in your CI pipeline
- Stay updated with browser and tool updates regarding WebP support
WebP isn’t going away—in fact, it’s becoming more embedded into the fabric of web development and digital design. With the right quick utilities and shared understanding across your team, working with WebP can be seamless, efficient, and even enjoyable.
