Start with a document you can upload
Use an owned public brochure, a project handout or another document you are authorized to process. Remove unrelated private information before using an external service. Keep the original file so you can compare the extraction with the page that supplied it.
This task starts with a document whose text cannot be selected. If you already have a readable caption in a screenshot, the screenshot-text checklist covers the shorter route.
Prepare and convert the file
Google Drive supports conversion of multipage PDFs and JPEG, PNG and GIF images. Its preparation guidance recommends a file of 2 MB or less, upright pages, sharp text and good contrast. On a computer, right-click the file in Drive and choose Open with, then Google Docs. Source
These are preparation recommendations from Google, not an accuracy promise. If your file falls outside them, retain that limitation instead of inventing a successful extraction. Do not upload a private account archive just because the tool accepts PDFs.
Inspect reading order before copying a phrase
Google warns that lists, tables, columns, footnotes and endnotes may not be detected correctly. Source Compare each phrase you intend to use with its location in the original.
| Original-page feature | Check in the extracted text | Keep unresolved when |
|---|---|---|
| Two columns | Words remain in the same reading sequence | Sentences appear spliced together |
| A table | Each value remains attached to its row label | The label-to-value relationship is missing |
| A caption beside a picture | Caption and main paragraph stay separate | The speaker or subject becomes ambiguous |
| A footnote marker | The qualification remains attached to the claim | The note is absent or illegible |
Imagine your own event handout has one column for the venue and another for the speaker. Combining both into a single sentence could create a statement that neither column makes. This is an illustrative error check, not a result from a tested document.
Make a bounded search note
Save the page number, visible phrase, extracted phrase and any correction you can justify from the original. Mark unreadable characters as unresolved. Do not ask an AI system to fill missing names and then treat the completion as OCR output.
Search a checked, distinctive phrase and inspect the resulting page using the public-source review workflow. The extraction supplies a query clue; the destination page supplies context.
