Compression level
Reduce PDF file size when an email or upload limit gets in the way. Choose a compression level that fits your document: light compression preserves image detail, while higher levels trade some image quality for a smaller file.
How it works
- Upload the large PDF.
- Compression optimizes images and embedded resources.
- Download the smaller PDF and send it on its way.
Why use this tool
- Three compression levels let you choose the quality-size trade-off.
- Ideal for email attachments, upload forms and slow connections.
- Text stays selectable; image quality depends on the compression level you choose.
Frequently asked questions
How much smaller will my PDF get?
It depends on the document. Image-heavy PDFs may shrink substantially; text-only or already-optimized PDFs usually shrink less.
Will compression damage my document?
Text remains selectable. Light compression preserves embedded images; Medium and High may reduce image detail to save more space. Review the result before sharing.
Can I choose the compression level?
Yes. Choose Light, Medium or High compression before starting. Light preserves the most image detail and color; High produces the smallest files.
Is there a size limit for input?
Free and Basic accept files up to 50 MB per file. Pro accepts files up to 100 MB. Paid plans have no daily cap for standard conversions; OCR is limited by monthly credits.
