THM Image Conversion: Batch Convert, Resize & Organize
THM files are thumbnail images generated by digital cameras and phone cameras. A .thm file pairs with a video or photo to provide a fast preview for playback menus — you'll see them in DCIM folders on Canon, GoPro, Sony, and many other cameras. Most are just renamed JPEGs at low resolution (160×120 to 640×480). Contenta Converter PREMIUM opens .thm files directly and batch-converts them to standard JPEG.
Contenta Converter PREMIUM lets you open, convert, and batch process THM files into modern formats like JPG, PNG, TIFF, PDF, and more. Optimize file size, keep important metadata, and prepare images for web, print, or long-term archiving in just a few clicks.

| Description | THM files are thumbnail images generated by digital cameras and phone cameras. A .thm file pairs with a video or photo to provide a fast preview for playback menus — you'll see them in DCIM folders on Canon, GoPro, Sony, and many other cameras. Most are just renamed JPEGs at low resolution (160×120 to 640×480). Contenta Converter PREMIUM opens .thm files directly and batch-converts them to standard JPEG. |
| Benefits | Useful for recovering video previews when the main video file is missing or corrupt. Essentially JPEG under the hood — converts quickly and losslessly to standard .jpg. |
| Drawbacks | Low resolution (previews only, not the original footage). Most image viewers and social platforms reject the .thm extension without conversion. Nothing in the preview was editable — the real media sits in the paired video file. |
