About FSTHUMB files

The .FSTHUMB file is a cached thumbnail image generated primarily by Wondershare Filmora (and occasionally linked to NCH VideoPad in older datasets) to speed up video preview rendering. These files are typically stored in hidden temporary folders and are not designed to be opened directly by users. Because they are technically standard PNG images disguised with a proprietary extension, users often encounter friction when trying to view them outside the video editor - standard image viewers like Microsoft Photos or Adobe Photoshop will not recognize the extension. While safe to delete (the software will regenerate them), users frequently need to convert them to JPG or PNG to recover a specific frame or preview the content without launching the heavy editing suite. For web use, convert to WebP; for archiving, PDF is recommended.

Convert.Guru analyzes your FSTHUMB file, detects the exact format, and lets you read the text inside.

Users also converted WFP, WVE and FILMF files.
