# See PDF info: pages, page size, fonts, security See a PDF's title, author, page count, page size, fonts, encryption and permissions in SumatraPDF with **Document Properties** and **Show PDF Info**, or from the command line with `sumatrapdf-tool info` and `pages`. **Show PDF Info and the command-line tools are available in [pre-release 3.7](https://www.sumatrapdfreader.org/prerelease)** **Press `Ctrl + D` for Document Properties.** At a glance: - **Document Properties:** `Ctrl + D`. Metadata, PDF version, page count, size of the current page, permissions, encryption, signatures and fonts, in plain words. - **Show PDF Info:** the same report as `sumatrapdf-tool info`: metadata, encryption, page sizes, fonts and images, with PDF object numbers. - **`sumatrapdf-tool info`:** that report in a terminal, with options to show only fonts, images or page sizes. - **`sumatrapdf-tool pages`:** the size boxes and rotation of every page. ## See Document Properties Open it in any of these ways: - **File → Properties** - `Ctrl + D` - Right-click the document → **Document → Properties** - Right-click the tab → **Properties...** - `Ctrl + K`, then `Document Properties...` in [Command Palette](Command-Palette.md) (`CmdProperties`) For a PDF it shows, when the file has them: - **File**, **File Size**, **File Type** - **Title**, **Subject**, **Author**, **Copyright**, **Keywords** - **Created**, **Modified** - **Application** (the program that made the document) and **PDF Producer** (the program that made the PDF) - **PDF Version** - **Denied Permissions:** `printing document`, `copying text` - **Encryption**, e.g. `Standard V5 R6 256-bit AES` - **Signatures:** digital signatures and whether they are valid (see [Sign a PDF](Sign-a-PDF.md)) - **Fast Web View** and **PDF Optimizations** (Tagged PDF, PDF/A, PDF/X, PDF/E) - **Number of Pages** - **Current Page (N) Size:** in cm, mm, inches and points, with the paper name, e.g. `(A4)` or `(Letter)`. Your locale's unit comes first. - **Fonts:** every font, with its type, encoding and whether it is embedded, e.g. `Georgia (TrueType; Ansi; embedded)`. The list appears a moment after the window opens. Click **Copy To Clipboard** to copy all of it as text. Press `Esc` to close the window. Document Properties also works for other formats (EPUB, comics, images...), with the fields that format has. For images it shows the size, DPI and camera (EXIF) details. ## See Show PDF Info Open it in any of these ways: - Right-click the document → **Document → Show PDF Info** - `Ctrl + K`, then `Show PDF Info...` in [Command Palette](Command-Palette.md) (`CmdPdShowInfo`) It's only shown for PDF files. It opens a **PDF Info** window with the same text that `sumatrapdf-tool info file.pdf` prints (see below). Use it when you need object numbers, for example to [extract a font](Extract-fonts-from-PDF.md) or an image. ## See PDF info from the command line Use `sumatrapdf-tool.exe`, or [SumatraPDF.exe ](Tools.md) with the same arguments. ``` sumatrapdf-tool info report.pdf ``` ``` report.pdf: PDF-1.7 Info object (13 0 R): <> Pages: 3 Not a ZUGFeRD file. Retrieving info from pages 1-3... Mediaboxes (1): 1 (6 0 R): [ 0 0 595 842 ] Fonts (1): 1 (6 0 R): Type1 "Helvetica" WinAnsiEncoding (3 0 R) ``` - `PDF-1.7` is the PDF version. - `Info object` has the metadata: title, author, creator, producer and dates (`D:20260217025405-08'00'` is 2026-02-17 02:54:05, UTC-8). - `Pages:` is the page count. - `Mediaboxes` lists each different page size once, in points (1/72 inch): `[ 0 0 595 842 ]` is 595 x 842 pt, which is A4 (210 x 297 mm). `612 x 792` is US Letter. - `Fonts` and `Images` list the resources used on each page. The number in brackets at the end is the object number. - `Not a ZUGFeRD file.` means the PDF has no embedded electronic invoice. Show only some of it: - `-F` fonts, `-I` images, `-M` page sizes (media boxes) - `-P` patterns, `-S` shadings, `-X` form XObjects - a page list at the end, e.g. `sumatrapdf-tool info -F report.pdf 2-3` See [sumatrapdf-tool info](Tool-info.md) for all options. ### See if a PDF is encrypted An encrypted PDF has an `Encryption object` in the `info` output: ``` Encryption object (0 0 R): <>>>/O<...>/U<...>/OE<...>/UE<...>/Perms<...>>> ``` - `/Length 256` with `AESV3` is 256-bit AES; `AESV2` is AES-128. - `/P` holds the permission flags; **Denied Permissions** in Document Properties shows the ones that matter for reading (printing, copying text). If the PDF needs a password to open, `info` fails with `argument error: cannot authenticate password`. Add the password with `-p`: ``` sumatrapdf-tool info -p secret locked.pdf ``` To remove the password, see [Decrypt a PDF](Tool-x-decrypt-pdf.md). ## See the size of every page `info` lists each page size once. To see every page, with rotation and all size boxes, use `pages`: ``` sumatrapdf-tool pages mixed.pdf ``` ``` mixed.pdf: ``` - Sizes are in points (1/72 inch): width is `r - l`, height is `t - b`. - `Rotate v="90"` means the page is shown turned 90 degrees, so this Letter page is displayed in landscape. - A page with a **CropBox** (visible area), **TrimBox**, **BleedBox** or **ArtBox** lists those too. See [sumatrapdf-tool pages](Tool-pages.md). - Add a page list to see some pages only: `sumatrapdf-tool pages mixed.pdf 2`. ## Tips - Use **Copy To Clipboard** in Document Properties to paste the details into a bug report or an email. - Use `sumatrapdf-tool pages` to find pages of a different size before printing (see [Printing](Printing.md)). - To check many PDFs at once, see [Process many PDFs at once](Batch-process-PDFs.md). - Use `sumatrapdf-tool info` on a file that won't open elsewhere; warnings about a broken xref mean it needs [repair](Repair-a-damaged-PDF.md). ## See also - [Extract fonts from a PDF](Extract-fonts-from-PDF.md) - [sumatrapdf-tool info](Tool-info.md) and [sumatrapdf-tool pages](Tool-pages.md) - [Encrypt a PDF](Tool-x-encrypt-pdf-with-password.md) and [Decrypt a PDF](Tool-x-decrypt-pdf.md) - [All cmd-line tools](Tools.md)
