Important limits

Local processing. Maximum 50 MB per input, 100 MB total, 20 files and 2,000 total pages. Encrypted or malformed PDFs are rejected. Edits common document Info fields only. It does not alter visible content, XMP, attachments, page-level metadata or digital signatures.

Choosing the next step

Start with the least destructive operation that solves the job. Page organization preserves more of the source than raster compression; compression is useful for scans but can remove selectable text; flattened redaction removes the original object layer but requires you to mark every sensitive area yourself.

Compress PDFRebuilds every page from a compressed JPEG at a chosen resolution to reduce image-heavy and scanned PDFs.Visual PDF EditorRenders each PDF page and lets you click to place text or drag highlights, lines and whiteout covers directly on the document.PDF Form FillerDetects named AcroForm text boxes, checkboxes, dropdowns, radio groups and option lists, then fills them in a new PDF copy.
