Why Won't My WebP Image Open? How to Convert WebP to PNG
Understanding Why WebP Files Sometimes Fail to Open
WebP is a modern image format developed by Google for efficient compression and smaller file sizes. However, many applications and devices, especially older ones, lack native support for WebP, causing images to fail when opening or displaying incorrectly.
If you see error messages or blank thumbnails when trying to open a WebP file, the root cause is often software incompatibility rather than file corruption.
Why Convert WebP to PNG? Format Differences and Use Cases
PNG is a widely supported lossless image format compatible with virtually all operating systems, browsers, and editing software. Unlike WebP, which uses both lossy and lossless compression, PNG maintains high image quality but usually at larger file sizes.
Converting WebP to PNG is ideal when you need broad compatibility for editing, printing, or archiving images without quality loss. For example, designers working in Adobe Photoshop or office workers embedding images in presentations often prefer PNG for its universal support.
Comparing Quality and File Sizes: WebP vs PNG
WebP achieves up to 30% smaller file sizes than PNG at similar quality levels by using advanced compression algorithms. For instance, a 1 MB PNG image can be compressed to approximately 700 KB in WebP format with negligible quality loss.
However, when converting WebP back to PNG, expect a file size increase of 40-60% depending on the image complexity, since PNG uses lossless compression and stores all pixel data.
Step-by-Step Fix: How to Convert WebP to PNG
To fix WebP compatibility issues, converting to PNG is straightforward and effective. Here's a recommended process:
- Upload your WebP file to a reliable conversion tool like Convert WebP to PNG.
- Select PNG as the output format.
- Start the conversion process, which usually completes within seconds for files under 5 MB.
- Download the converted PNG file and verify it opens correctly in your preferred software.
This method ensures your image is accessible without losing detail or color accuracy.
When to Use WebP and When to Use PNG
Use WebP primarily for web projects where reducing file size improves page loading speed without visible quality degradation. Photographers and web designers benefit from WebP’s smaller files, which can be 25-35% smaller than JPEG or PNG.
Use PNG when you require full compatibility, transparency support, or editing flexibility. For print materials, PNG’s lossless quality preserves sharpness and color fidelity.
Common Problems Solved by Converting WebP to PNG
Converting WebP to PNG resolves several issues:
- Failure to open images on legacy software like Microsoft Office or older versions of macOS Preview.
- Loss of transparency or color shifts when WebP is not fully supported.
- Inability to print or embed WebP images in documents requiring universal formats.
By converting, you ensure your images remain versatile and accessible.

FAQ
Why won't my WebP file open in Microsoft Word?
Microsoft Word does not natively support WebP format. Converting your WebP image to PNG ensures compatibility across all Office applications without quality loss.
Does converting WebP to PNG reduce image quality?
No. PNG uses lossless compression, so converting WebP (lossy or lossless) to PNG preserves image quality but results in larger file sizes.
Is PNG always better than WebP?
Not always. WebP offers smaller file sizes ideal for web use, while PNG is preferred for editing, printing, and universal compatibility.
How much larger is a PNG compared to the original WebP?
On average, PNG files are 40-60% larger than their WebP counterparts due to lossless compression storing more data.
