Adobe Acrobat Reader DC

About Adobe Acrobat Reader DC

Reader is the baseline against which every other PDF viewer gets judged, mostly because it renders the format the way the format was specified rather than approximately. Complex documents with transparency, layered artwork, embedded fonts, form logic and colour managed images display correctly, which is not something every lightweight alternative can claim once a real production file arrives.

For reviewing, the commenting toolset is complete: sticky notes, highlight, strikethrough, underline, freehand drawing, shapes, stamps and text callouts, all with author attribution and a comment list that can be sorted, filtered and exported. Comments made here open correctly in the full editor, so a review cycle does not need everyone on the same application.

Forms and signatures cover the administrative side. Interactive forms fill and validate properly, including calculated fields and dropdown logic that simpler viewers ignore, and a form without fields can be completed with the fill and sign tools. Signatures can be typed, drawn or applied from a certificate, and certificate based signatures validate against the document rather than just appearing on it.

The reading experience itself is well covered. Continuous, single page and two page spreads, reflow for reading a print layout on a small screen, read out loud, full text search across a document or a folder, bookmarks and thumbnails, and a protected mode that opens documents in a sandbox so a malformed file cannot reach the rest of the system.

Installation walkthrough

These steps assume a clean machine. If a previous release of the same application is present, deal with that first, since an overlapping install is the most common cause of a setup that stops halfway.

1. Close every browser window first, since the document handler registers during setup.
2. Extract the archive to any folder with a short path.
3. Run the installer as administrator.
4. Choose whether to make it the default handler for the document type during setup.
5. Open one document afterwards and confirm protected mode is enabled in preferences.
