Compress PDF - Frequently Asked Questions

How much can I reduce my PDF file size?
Results vary depending on the content, but you can typically reduce PDF size by 50-90%. PDFs with many images compress more than text-only documents. Scanned documents usually achieve the best compression ratios.
Will compression affect text quality?
No, text remains sharp and readable. Our smart compression algorithm primarily optimizes images and removes unnecessary metadata while preserving text clarity. The document remains fully searchable and selectable.
Can I compress a PDF to exactly 1MB for email?
Our compressor optimizes the file as much as possible while maintaining quality. For most documents, you'll get a file under 1MB. If the result is still too large, try splitting the PDF first, then compressing each part.
Is the compressed PDF still printable?
Yes, compressed PDFs are fully printable. While images are optimized for screen viewing, text and vector graphics remain at full quality. For high-quality printing needs, we recommend keeping the original file.
Can I compress scanned documents?
Yes! Scanned PDFs often benefit the most from compression since they contain large images. Our tool can significantly reduce the size of scanned documents while keeping the content readable.
