Frequently Asked Questions

Which 9 operations does Bulk PDF Suite cover?

Rotate (90/180/270), password-protect, unlock (with password), split by page count, text watermark, margin crop, page resize (A4/Letter), and form flatten — each applied uniformly across the whole batch. A 50-file scan cleanup (rotate + compress-ready + flatten) finishes in one session.

How many PDFs fit in one batch?

Signed-in free users batch up to 25 files per run within 2 Pro downloads a day; Pro handles up to 500 files to 2 GB each. A 125 MB-per-file ceiling applies — split oversized scan sets before starting.

Are my PDF files uploaded anywhere?

No — all nine operations run locally in your browser on pdf-lib, so documents never leave your device. Only the final ZIP or file saves count against the Pro download quota; processing itself has no cap.

How do I watermark CONFIDENTIAL across 50 files?

Drop the batch, choose Watermark, type the text, set diagonal placement at 30% opacity, and run — every page of all 50 files stamps identically. Preview one file first: opacity that looks subtle on screen can vanish in print.

Can I unlock password-protected PDFs in bulk?

Yes when you know the password — enter it once and the suite unlocks every file in the batch. Files with unknown passwords cannot be processed; that is a hard limitation, not a missing feature.

What is flattening and when do I need it?

Flattening converts fillable form fields and annotations into static page content so recipients see exactly what you see. Flatten signed offer letters and court filings before sending — unflattened forms can render differently on the recipient's reader.
