Does Compression Affect Image Quality for E-learning Courses?
Yes, but how much depends on your settings. Course platforms serve the same images to many students, often on slow connections, so lean files improve the learning experience.
Recommended settings for e-learning courses
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1600 px on the long edge |
| Quality | 78 |
| File size | 200 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
Does Compression Affect Image Quality
Light compression at quality 85 is practically invisible. Heavy compression below 50 shows blocky patches in skies and smudged edges around text.
For e-learning courses, quality 78 sits in the sweet spot. Check your result on the kind of screen your audience will use, not only on a large monitor.
