Previewing HEIC, WebP, and rare image formats on Windows
By Sébastien · · 4 min read
A reference photo shot on an iPhone (HEIC), a visual grabbed off the web (WebP), a high-resolution scan (TIFF): these images feed a lot of maker projects, but Windows displays them poorly or not at all. This article complements the guide on previewing your files without opening the original software.
Why Windows chokes on HEIC and WebP
HEIC (the default photo format on iPhones) needs a paid extension to show up in the explorer; without it, no thumbnail. WebP and TIFF sometimes work, often not. The result: empty thumbnails or a forced conversion before you can even look at the image.
See without converting
The classic mistake is converting an entire folder of HEIC to JPEG just to look at them — which duplicates everything and degrades quality. A visual manager like PandaFile displays HEIC, WebP, TIFF, and RAW thumbnails directly, with no conversion or extension to install. You pick the right image, then convert only that one if needed.
- HEIC / HEIF: recent iPhone and Android photos
- WebP / AVIF: modern web images
- TIFF: scans and printing
- RAW (CR2, NEF, ARW…): raw photography
Once your images are visible, file them with the rest: see organizing your graphic files.
Frequently asked questions
Why won't my HEIC photos show on Windows?
Windows only displays HEIC with a dedicated (often paid) extension. Without it, no thumbnail. A visual manager shows HEIC files without any extension or conversion.
Do I need to convert HEIC to JPEG?
Not just to look at them: that duplicates the files and loses quality. It's better to preview them directly, then convert only the image you actually need.
Can I view WebP and RAW images too?
Yes, a visual manager generates thumbnails for WebP, AVIF, TIFF, and camera RAW files — formats Windows Explorer shows poorly or not at all.
