💡 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.
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
Will compression remove text from my PDF?
No. Compression is designed to reduce file weight, not remove readable text. Text layers should remain searchable when the original PDF already contains searchable text.
Is the Compress PDF free to use?
Yes. The core Compress PDF workflow is available from the browser without installing software. Some higher-volume or larger-file tasks may require a paid plan.
Do I need to create an account?
Most tools can be used without an account. Signing in is only needed for account features, subscriptions, or workflows that require saved access.
What happens to uploaded files?
Files are used only to complete the requested conversion or edit. Browser-based tools process locally where possible, and server-processed files are handled through encrypted requests.
