- Should I use JPEG or PNG for my thumbnail?
- JPEG produces smaller files and is best for sharing and web use. PNG is lossless and better when you need pixel-perfect quality, such as for editing or overlay work.
- Can I use this for YouTube thumbnails?
- Yes. Extract a frame at the perfect moment, then download it as JPEG. YouTube recommends 1280x720 images — if your video is 1080p or higher, the extracted frame will work great.
- How precise is the timestamp?
- The tool extracts the nearest frame at the specified second. For HH:MM:SS precision, this is accurate enough for thumbnails and cover images.
