Privacy Tips When Compressing Images for YouTube Thumbnails
Many online compressors upload your images to a server. That is not always necessary. Thumbnails are shown at many sizes across devices, and a clean, light file keeps text and faces crisp.
Recommended settings for YouTube thumbnails
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1280 px on the long edge |
| Quality | 78 |
| File size | 500 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
Privacy Tips When Compressing Images
TheCompressJPEG processes images in your browser. Nothing is sent anywhere, which matters for IDs, documents and family photos.
Before sharing images for YouTube thumbnails, also check the picture itself: addresses, licence plates and documents in the background can reveal more than you intend.
Step by step with TheCompressJPEG
- Open the compress JPEG to 500 KB tool, or the main compressor for custom settings.
- Drop in your image. Nothing is uploaded; it is processed in your browser.
- Set the maximum width to 1280 and the target size to 500 KB.
- Press Compress, check the result and download it.
Quick tips
- Always keep the original file and compress a copy.
- Use JPEG for photos and PNG for logos and line art.
- Name files descriptively with lowercase words and hyphens.
