How to Convert Gopro THM Images to PNG
Answer
You can use our software Contenta Converter PREMIUM to convert thousands of THM to PNG. Everything in one go and in just a few easy steps.| Format | THM | PNG |
| Company | Portable Network Graphics | |
| 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. |

What PNG quality settings should I use for web and print?

Can I use the trial version for client work?
