Image Compression Workflow for Facebook Posts
A repeatable workflow saves time and keeps results consistent. 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.
Image Compression Workflow
Keep originals in one folder and never overwrite them. Export compressed copies to a separate folder named for the destination, such as Facebook posts.
Use the same width (2048 px) and quality (78) every time so your images look uniform. Batch the work instead of compressing files one at a time.
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
- Check the result on a phone, where most people will see it.
- Use consistent dimensions for a set of related images.
- Resize before you compress; it improves quality at any file size.
- Write a size limit slightly below the stated maximum to leave a margin.
FAQ
Will compressing reduce image quality for e-learning courses?

How do I compress many images for e-learning courses at once?
Drop all of them into the tool together and use Download all to get a single ZIP.
What JPEG quality should I use for e-learning courses?
Quality around 78 keeps photos looking natural while cutting file size substantially.
Wrapping up
For Facebook posts, the reliable recipe is simple: resize to around 2048 pixels, compress at quality 78 or to a 400 KB target, and check the result before you upload. Keep the original so you can always start again.
