Frequently Asked Questions
Is PDF compression safe?
Yes, our tool performs lossless compression by default, meaning your document content remains unchanged. For stronger compression, some image quality may be reduced.
Is there a file size limit?
You can compress PDFs up to 50MB in size. For larger files, consider splitting the PDF first.
Are my PDFs stored on your servers?
No, all processing happens in your browser. Your files are never uploaded to our servers, ensuring complete privacy.
Does compression affect text quality?
Text remains sharp and clear in most cases. Only embedded images may lose some quality with strong compression settings.
What's the best compression level to use?
We recommend starting with the "Balanced" mode. For maximum compression, use "Strong" mode but check the results carefully.
