How to Compress Images for School Assignments on Windows
On Windows, a browser-based compressor avoids installing extra software. 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.
How to Compress Images
Open Edge, Chrome or Firefox, drag your photos from File Explorer into the drop zone, and set quality around 78.
For several files, use Download all to get a single ZIP. Extract it and your images are ready for school assignments with the original files untouched.
Step by step with TheCompressJPEG
- Open the compress JPEG to 300 KB tool, or the main compressor for custom settings.

- 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.
