Frequently Asked Questions
How much can I compress a PDF file?
Our PDF compressor can reduce file sizes by 30-90% depending on the original content and compression level selected. Documents with many images typically achieve higher compression ratios, while text-heavy PDFs compress less but still show significant size reductions.
Is PDF compression free and unlimited?
Yes, our PDF compression tool is completely free with no limits on the number of files you can compress. Unlike SmallPDF or other services, we don't require registration, have no daily limits, and never add watermarks to your documents.
Does compressing PDF reduce quality?
Our smart compression algorithm is designed to maintain visual quality while significantly reducing file size. We use advanced techniques like lossless text compression and intelligent image optimization. You can choose compression levels based on your quality vs size preferences.
How secure is your PDF compression service?
Security is our top priority. All files are processed with enterprise-grade encryption (AES-256), transmitted over secure HTTPS connections, and automatically deleted from our servers within 1 hour after compression. We never store, access, or share your documents.
What's the maximum PDF file size I can compress?
You can compress PDF files up to 20MB, which covers the vast majority of documents, presentations, reports, and ebooks. This limit ensures fast processing while accommodating most user needs. For larger files, consider splitting them first using our PDF split tool.
Does PDF compression work on mobile devices?
Absolutely! Our PDF compressor works perfectly on all devices including smartphones and tablets. The interface is fully responsive and optimized for touch interaction. No app download required - just use your mobile browser to compress PDFs anywhere, anytime.
How does your compressor compare to Adobe, SmallPDF, and PDF24?
Our compressor offers superior compression ratios, faster processing speeds, and better security than most competitors. Unlike SmallPDF's limited free usage or Adobe's subscription requirements, we provide unlimited free compression with no watermarks or registration needed.
Can I compress password-protected PDFs?
Currently, our tool works best with unprotected PDFs. For password-protected files, you'll need to remove the password protection first using our PDF unlock tool, then compress the file. This ensures optimal compression results and maintains security standards.
