About Compress PDF
Compress homework PDFs in the browser so WhatsApp and portals accept them — without uploading exam papers to a random site.
Compression runs in your browser. Files are not uploaded to Mentr servers.
WhatsApp size limits and school portals
Indian tutors live on WhatsApp. Large phone scans and image-heavy notes often fail to send. Compressing a PDF for WhatsApp is one of the highest-intent jobs on this hub — and it should not require uploading exam papers to an unknown cloud.
Light mode repacks the file. Strong mode scales pages slightly for a bigger size drop. Always open the result once before sharing with parents.
Quality vs size — a practical rule
Keep originals for printing answer scripts. Use Strong only for chat sharing. If readability suffers, split into smaller ranges instead of crushing one giant file.
