Compress Images for School Assignments
Learning Management Systems like Google Classroom, Canvas, Blackboard, and Moodle often have strict file upload limits. ImageGates helps students compress photos of handwritten work, lab reports, and project images to meet these limits without losing readability.
File size limits for school and university submissions
Learning platforms cap upload size per file and per submission, and scans of handwritten work are usually the culprit when a submission fails. Reducing scan resolution sensibly keeps the text readable well under the limits.
Exact specifications:
- Google Classroom: typically 100 MB per attachment
- Moodle: commonly 2–20 MB, set by the institution
- Canvas: commonly 500 MB course quota per student
- Readable scan resolution: 200–300 DPI for text
- Target per page: under 500 KB
What causes a rejected or degraded result:
- Scanning at 600 DPI in colour, which produces 10–20 MB per page for no readability gain.
- Submitting photos of pages taken at an angle rather than straightened scans.
- Compressing so hard that pencil work disappears — check the faintest line before submitting.
Preparation order that avoids rework:
- Scan or photograph at 300 DPI in greyscale for handwritten work.
- Straighten each page, then compress to roughly 300–500 KB.
- Combine pages into a single PDF where the platform allows it.

Guide
Students frequently need to photograph and upload handwritten assignments, lab reports, and project documentation. Phone cameras produce high-resolution images that often exceed LMS file limits.
Student image optimization workflow: 1. Photograph your work with good lighting 2. Crop unnecessary borders with ImageGates Cropper 3. Compress with ImageGates at 70-75% quality 4. Combine into PDF if submitting multiple pages 5. Upload to your school's LMS
Tips for photographing homework: - Use natural daylight or bright room lighting - Hold camera directly above the paper (avoid angle shots) - Ensure the entire page is in frame - Check focus before moving to the next page - Use your phone's document scanner mode if available
Frequently asked questions
How do I reduce the file size of homework photos?
Upload photos to ImageGates and compress at 70-75% quality. Handwritten text remains readable while file sizes drop by 80-90%. For text documents, grayscale conversion helps even more.
Can I combine multiple homework photos into one PDF?
Yes! After compressing individual photos, use our Image to PDF tool to combine all pages into a single PDF document for easy submission.
