Result assurance
Verify converted files and keep a recoverable backup
A successful download only proves that bytes were produced. Verification must test the properties important to the destination, while backups preserve the information a conversion intentionally or accidentally removes.
Workflow
Define acceptance before processing
Write down required format, size, dimensions or pages, orientation, transparency, text selection, links, forms, signatures, metadata, and destination compatibility.
Inspect the actual download
Open the saved file in a second suitable application, compare it with the source, and test the first, last, boundary, and visually complex regions.
Back up and name deliberately
Keep the source read-only, save the result under a new descriptive name without confidential details, and record which settings and date produced it.
Limits to understand
Visual comparison alone cannot prove metadata removal, PDF structure preservation, accessibility, cryptographic validity, or compatibility with every recipient. A checksum proves identity, not correctness.
Privacy mode
Store backups according to sensitivity and retention rules. Local conversion avoids an upload during processing, but synced folders, email, backup services, and recipients create new data copies.
Verify the result
For images check format, dimensions, alpha, color, and artifacts; for PDFs check page count/order/size, text, links, forms, signatures, attachments, and print output as relevant, then test the real destination.
Frequently asked questions
When can I delete the original?
Only after the result is accepted, retention duties are satisfied, and a verified backup exists. Many lossy or destructive operations justify keeping it indefinitely.
Is reopening the file enough?
No. Reopening detects gross corruption, but you must also test the specific properties and workflows that matter to the recipient.
