Frequently Asked Questions
What are the different compression levels available?
Our tool offers three compression levels: Low (high quality, minimal size reduction), Medium (balanced size and quality), and High (maximum size reduction, lower quality). Choose based on your specific needs.
Will compression affect the quality of my PDF?
The impact on quality depends on the compression level chosen. Low compression maintains high quality, while high compression may reduce image quality but significantly reduces file size.
What happens to my files during processing?
Your files are processed entirely in your browser and never uploaded to our servers. This ensures complete privacy and security of your documents.
Are there any file size limitations?
Yes, the tool supports PDF files up to 50MB in size. For larger files, consider splitting them first or using desktop software.
What elements can be compressed?
Our tool can compress images, remove metadata, and optimize fonts within your PDF to reduce file size while maintaining readability.
Can I compress multiple PDF files at once?
Currently, the tool processes one PDF file at a time. For multiple files, you'll need to compress them individually.
What if the compression process fails?
If compression fails, it may be due to file corruption or unsupported PDF features. Try a different file or adjust the compression settings.
