Does compressing a PDF reduce quality?

PDFPulp uses balanced compression that reduces file size while preserving text sharpness and image clarity. For most documents — reports, presentations, scanned pages — the difference is imperceptible. Text-based PDFs compress especially well since text vectors are lossless.

How much can a PDF be compressed?

It depends on the content. PDFs with embedded high-resolution images typically shrink 50-80%. Text-heavy documents with few images may only reduce 10-30%. Scanned documents usually see the largest reductions.

Is it safe to compress PDFs online?

PDFPulp uses AES-256 encryption for all file transfers. Your files are processed on isolated AWS Lambda functions and automatically deleted within 24 hours. We never access, analyze, or store your document content.

Can I compress a PDF for email?

Yes — this is the most common use case. Gmail limits attachments to 25MB, and Outlook to 20MB. PDFPulp can typically compress a 30MB PDF well below these limits in seconds.

Do I need to create an account?

No. PDFPulp works without login or registration. Drop your file, compress it, and download — no account required. Free users get 5 operations per day.

Will there be a watermark on my compressed PDF?

Never. PDFPulp does not add watermarks on any tier. Your compressed PDF is clean output, identical to the original except smaller.
