PDF

Keeps or removes a page range such as "1-3,7,12-" and writes the result as a new PDF.

Shows every page as a thumbnail so you can reorder, duplicate, rotate or delete them.

Downsamples embedded images, subsets fonts and drops unused objects to reduce file size.

Fills in a received PDF for submission: tick checkboxes, type text and dates, place a signature or stamp, then flatten.

Joins several PDFs into one, with drag-to-reorder and per-file page ranges.

Encrypts a PDF with an open password and/or a permissions password — AES-256 by default, AES-128 and RC4 for old readers — and sets printing, copying, editing and annotation permissions.

Removes the open password or permission restrictions from a PDF you can already open, given its password — RC4 and AES files alike — and writes it back in the clear.

Deletes the underlying text and image content inside marked areas, not just a black rectangle on top.

Splits a PDF at chosen page breaks, every N pages, or on bookmark boundaries.

Finds ruled tables from the lines drawn on each page — merged cells included — and borderless ones from aligned columns, then exports each as CSV or TSV. Values are as printed; column types are not guessed.

Pulls the text layer out of a PDF in reading order — columns, rotated pages and Korean CID fonts included — as plain text or Markdown, and names any font it could not decode.

Typesets Markdown to PDF — headings, lists, tables, code blocks and quotes — with base-14 fonts. Korean text needs a font it cannot embed.

Lays 2, 4, 6 or 9 pages onto each sheet with adjustable margins and cut marks.

Adds page numbers, headers and footers with a start offset and a chosen numbering format.

Adds highlights, notes, shapes and freehand ink, and exports the comment list separately.

Diffs two PDFs both as text and as rendered pixels, listing insertions, deletions and moves.

Trims page margins uniformly or per page, with automatic detection of the content box.

Merges annotations, form fields and layers into the page content so they cannot be edited or hidden.

Fills AcroForm fields by hand or from a CSV row, and can flatten the result so it cannot be edited.

Lists every embedded image with its resolution and exports the ones you pick at original quality.

Views and removes author, producer, creation dates, XMP blocks and embedded file attachments.

Scales and centres page content onto a different paper size such as A4, Letter or B5.

Rotates chosen pages by 90° steps and can auto-orient pages from the text direction.

Overlays text or an image watermark on every page with angle, opacity and layer position.

Checks a supposedly redacted PDF for text, images or metadata still hiding under the black boxes.

Thresholds a scanned PDF to bilevel, despeckles, crops to the ink and can drop blank pages. It does not OCR or deskew.

Reorders and pairs pages for saddle-stitch booklet printing, with signature size and creep control.

Builds or edits the outline tree, including generating one from headings or a pasted list.

Reads the filled field values out of one or many form PDFs into a single table.

Rewrites a PDF into the linearised layout of ISO 32000-1 Annex F — first-page section, page offset and shared object hint tables, split cross-reference — and reports how few bytes page 1 now needs.

Rebuilds a broken cross-reference table and recovers the readable pages of a damaged PDF.

Walks the object tree, listing fonts, colour spaces, JavaScript, attachments and per-page byte weight.

Converts to PDF/A-2b or PDF/A-1b — XMP identification, an sRGB output intent computed from IEC 61966-2.1, no encryption, no scripts — and refuses, with reasons, when a font is not embedded or a page paints in CMYK.
