What this tool does
Render pages at 86 DPI and rebuild them as JPEG images in a PDF. Designed for scanned documents. This changes page content to images and removes searchable text, forms, links, accessibility tags, and digital signatures. If the output is larger, the original file is returned unchanged. Maximum 20 pages; reduction is not guaranteed.
Supported files, limits & important details
20 MB combined input; up to 10 files when supported. PDF editing: 200 pages maximum. Splitter: 50 pages. PDF image export/compression: 20 pages, 12 million pixels per page, 80 MB output. Image inputs: 20 million pixels each. Encrypted, damaged, and empty PDFs are rejected. Structural editing rejects interactive form fields.

Editing may lose document-level bookmarks, attachments, and accessibility tags. Keep originals and inspect output before relying on it.
