Lossy vs Lossless Compression for Landing Pages
Image compression comes in two flavours. Landing pages live or die by load speed, and images are usually the heaviest part of them.
Recommended settings for landing pages
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1600 px on the long edge |
| Quality | 70 |
| File size | 150 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
Lossy vs Lossless Compression
Lossless compression, as in PNG, keeps every pixel exactly and saves modest space. Lossy compression, as in JPEG and WebP, discards detail the eye barely notices and saves far more.
For photographs used for landing pages, lossy is the practical choice. Save lossless formats for graphics where every pixel edge matters.

FAQ
What JPEG quality should I use for e-learning courses?
Quality around 78 keeps photos looking natural while cutting file size substantially.
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.
Wrapping up
For landing pages, the reliable recipe is simple: resize to around 1600 pixels, compress at quality 70 or to a 150 KB target, and check the result before you upload. Keep the original so you can always start again.
