Before processing
Plan which comments, highlights, drawings, or callouts belong on each page, use a consistent review convention, and avoid covering source text or signatures.

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

After processing
Review, download, and continue after Annotate PDF
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 outputAdd supported highlights, drawings, notes, or shapes directly to pages and export an annotated review copy.
Check page order, orientation, text, permissions, and any visible signatures before sharing the PDF.
Review the output
Check page order, text, orientation, and the number of files in the workspace before sending anything.
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.
Delete now when offered
If this workspace offers Delete now, use it after downloading. Availability depends on the tool and current result path.
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
Return visual feedback on a design proof
Starting point
A design proof needs comments tied to exact page areas rather than a separate list of ambiguous notes.
Result to check
Highlight the relevant areas, add concise annotations, and inspect the marked-up PDF before returning it to the designer.

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.
