Rotate, protect, unlock, split, watermark, crop, resize, or flatten dozens of PDFs in one batch. Law firms prep 50 filings for email in an afternoon — runs locally on pdf-lib, 2 free batches a day.
Runs on pdf-lib

Stamp text or logo watermarks across dozens of photos with 5 positions and 10–100% opacity control. Photographers protect 200 wedding proofs before sharing — always exports PNG (<name>-watermarked.png) — local Canvas work, 2 free batches a day.
Convert whole batches of audio between WAV, MP3, and OGG with one output format and sample rate for the whole batch. Podcasters standardize 50 episodes for every platform — local processing, 2 free batches a day.
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.
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.
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.
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.
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.
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.
