Frequently Asked Questions (FAQ)

How much can the compressor reduce file size?

Depends on content. Image-heavy PDFs can be reduced 60-80%. Text-only PDFs typically see 10-30% reduction.

Does compression affect text readability?

Text is not compressed - it remains perfectly readable at all compression levels. Only embedded images are optimized.

Can I compress password-protected PDFs?

No, unlock the PDF with our PDF Unlocker first, then compress it.

What compression algorithm is used?

Image content is re-compressed using JPEG/WebP at reduced quality. The PDF structure is also optimized by removing redundant data.

Is there a file size limit for input PDFs?

No server limit. Your device's available RAM determines practical limits - most PDFs process without issues.

Is my data safe when using the PDF Compressor?

Yes, completely. All calculations and file conversions happen entirely inside your own browser. We do not store, view, or upload any of your input data to our servers.

Do I need to sign up or pay to use this tool?

No. UtilsGo is 100% free. You don't need to create an account, register, or pay for any features.
