PDF Reader: from your file to a checked result

Open a document, move through its pages, and use the review options currently available in the viewer. The three decisions below show what to provide, what to configure, and what to verify before you share the output.

Plan the job

Prepare and verify PDF Reader

A quick source check prevents avoidable rework. After processing, open the output and verify the details that matter for this specific PDF task.

Before processing

Confirm the PDF opens completely and identify bookmarks, attachments, forms, signatures, layers, right-to-left text, or accessibility needs that affect how it should be reviewed.

Before relying on the result

Navigate first, middle, and final pages, test search, zoom, links, bookmarks, selection, forms, and attachments, and verify important content against another trusted viewer if needed.

How it works

How to use PDF Reader in three steps

  1. Choose the PDF you want to read.

  2. Navigate through the document in the viewer.

  3. Add review annotations if needed and export the result when available.

Complete the job

PDF Reader from upload to a checked result

Follow the whole path before you start: choose the source, set the job, run the workspace, verify the output, and continue only when the result is right for its next use.

  1. Choose the source

  2. Configure the job

  3. Run the tool

  4. Check the result

  5. Continue

After processing

Review, download, and continue after PDF Reader

A completed result still deserves a quick check. Keep the original, inspect the output type and contents, and decide what should happen next before you share it.

Output to verify

Result type: PDF output

Open a document, move through its pages, and use the review options currently available in the viewer.

Check page order, orientation, text, permissions, and any visible signatures before sharing the PDF.

  1. Review the output

    Check page order, text, orientation, and the number of files in the workspace before sending anything.

  2. Download your copy

    Use the workspace Download action after the result is ready. A browser handoff does not prove that a file was saved to disk.

  3. Delete now when offered

    If this workspace offers Delete now, use it after downloading. Availability depends on the tool and current result path.

  4. Continue with the next task

    Keep the source until you have verified the result, then move to a related PDF task or return to the tools catalog.

Practical example

Review a PDF on a computer without a desktop reader

Starting point

A colleague sends a multi-page brief that needs to be checked quickly in the browser before a meeting.

Result to check

Open the PDF, navigate to the relevant pages, and use available annotations or export options when the review calls for them.

Premium and PDF Reader

When PDF Reader needs more than Free

Free covers three completed jobs a day, 25 files, 100 MB, and 500 pages per task. Premium raises those limits and adds OCR, existing-text editing, repair, compare, forms, and automation.

Usually next: Keep the result and move straight into the next tool without re-uploading.

  • No daily job cap, subject to fair-use protection

Work with confidence

Clear limits and an output you can review

Know the access level

The first eligible task can be completed before login. Current file, page, and usage limits are shown in the workspace.

Keep document data out of analytics

TapScanner web's application data layer rejects filenames and document contents. Published analytics destinations require separate configuration verification.

Temporary storage during processing

Hosted processing paths may use temporary files. In the pinned core's normal download path, the output file is removed when the stream closes; scheduled cleanup covers stale temporary files.

Hosted processing

Web tools may send files to TapScanner's hosted processing service. We do not currently offer a customer-selectable processing region, so do not assume processing stays on your device or in a particular country.

Delete when offered

Delete-now is available only when a result screen explicitly offers it; it is not yet supported by every web tool.

Check the finished file

Open the downloaded result and verify important pages, values, formatting, and permissions before relying on it.
