💡 Compression Tips
Choose Quality Wisely
Balance file size and quality based on use. For archiving, use higher quality; for email, maximum compression.
Optimize Images First
For best results, compress images before converting to PDF, or use our image compression tool first.
Remove Unused Elements
Delete hidden layers, annotations, and form fields before compressing for maximum size reduction.
Consider Page Size
Larger page sizes (like A3) create bigger files. Scale down if appropriate for your needs.

Tool guide
Compress PDF guide, use cases, and best practices
Use the Compress PDF tool when a document is too large for email, forms, portals, or cloud uploads. The goal is to reduce file size while keeping text readable and images clear enough for the document purpose.
Common use cases
- Send reports, invoices, forms, and scanned documents through email limits.
- Prepare PDFs for school, job, visa, banking, and client upload portals.
- Reduce storage usage for document archives without rebuilding the file manually.
Best practices
- Use lighter compression for contracts, certificates, and files where image clarity matters.
- Use stronger compression for scans, drafts, and documents mainly meant for quick review.
- Check the compressed PDF before sharing it when the original contains small text or detailed charts.
Frequently asked questions
