Privacy Tips When Compressing Images for School Assignments
Many online compressors upload your images to a server. That is not always necessary. Learning platforms can have upload caps, and smaller files are easier to submit from a phone or a slow home connection.
Recommended settings for school assignments
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1600 px on the long edge |
| Quality | 78 |
| File size | 300 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 school assignments, 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 1600 and the target size to 300 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.
