Privacy Tips When Compressing Images for Facebook Posts
Many online compressors upload your images to a server. That is not always necessary. Facebook re-encodes uploads, and starting from a clean, right-sized JPEG gives it less room to introduce blocky artefacts.
Recommended settings for Facebook posts
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 2048 px on the long edge |
| Quality | 78 |
| File size | 400 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 Facebook posts, 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 300 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 2048 and the target size to 400 KB.
- Press Compress, check the result and download it.
Quick tips
- Use WebP where it is supported and you control the page.
- Never re-compress an already compressed JPEG if you can avoid it.
- Strip metadata from images you share publicly.
- Always keep the original file and compress a copy.

Wrapping up
