A .thm file is a thumbnail your camera saves next to each video (Canon, GoPro, Sony and others) so its playback menu can show a preview. Most THM files are ordinary JPEG images of 160×120 to 640×480 pixels: rename one to .jpg and Windows Photos opens it. It is only a preview; the footage stays in the video file.
ren *.thm *.jpg in Command Prompt inside the copy. The camera pairs previews by name, so keep the originals.صيغة |

| الوصف | صيغة ملف THM مماثل بشكل أساسي لصيغة ملف JPEG (JFIF). |
| الفوائد | 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. |
| عوائق | 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. |

Yes, for most cameras. THM files from Canon, GoPro, Sony and many other brands are JPEG images with a different extension, so renaming them to .jpg is enough. If a renamed file will not open, that camera stored its preview in another format.
No. It is only a small preview picture. The footage is in the video file with the same name, for example MVI_0001.MOV next to MVI_0001.THM. Deleting the THM does not delete the video.
Drop the folder into Contenta Converter, choose JPG and click Start Converting. Every .thm becomes a .jpg in one batch, and you can resize or rename them in the same pass.
