Scan preflight guide
How to check whether a scanned PDF has selectable text before you upload it
A portal can accept a PDF and still leave you with a document that is hard to search, review, or use with assistive technology. The trap is that a scan can look perfectly readable on screen while every word is only part of an image. You do not need to upload a sensitive file to a converter just to learn that. Check the text layer locally first, then choose the right next step for the destination.
Decision map
What to remember before choosing a file.
A readable-looking scan is not necessarily a searchable PDF; try selecting text or searching for a phrase before upload.
PDFTry can make a local report from an existing PDF text layer without a converter upload round trip.
An empty report means the scan may need full image OCR elsewhere; review the destination's rules before you submit it.
Local workflow
Use the no-upload route in four moves.
Chapter 1
A scanned page can be readable without being searchable
A scanner often saves each page as an image inside a PDF. You can zoom in and read the words, but a browser, a court filing system, or a screen reader may not be able to identify those words as text. A quick select or search test is a useful first check. It distinguishes a PDF with an existing text layer from a page that is only a picture of text.
Chapter 2
Use the local report as a preflight check, not as a promise of OCR
PDFTry's OCR Scanned PDF tool reads the PDF's available text layer and downloads a TXT report from the browser. That is useful for checking a scan before it takes another trip through an upload service. Its current browser-only version is not a heavy image-OCR engine, so it cannot create searchable text from an image-only scan. The honest result matters: an empty report tells you to stop and choose a proper OCR route rather than submitting on hope.
Chapter 3
Check a few meaningful words, not just whether any text appears
A report with a handful of characters is not automatically a usable document. Compare a heading, a name, a date, and a short sentence against the visible page. Poor scans, skewed pages, faint printing, unusual fonts, handwriting, and tables can all make recognition unreliable. If the destination requires a searchable or accessible PDF, follow its stated rule and review the final output yourself.
Chapter 4
Keep the inspection separate from the upload decision
Checking a file locally avoids an unnecessary converter upload while you are still deciding what the document needs. It does not determine whether a court, portal, employer, or agency will accept the file. Those systems can have their own requirements for format, file size, encryption, page order, naming, or searchable text. Use the smallest correct next action: inspect the text layer, run approved OCR when needed, then submit only the reviewed copy.
Common scenarios
Where this workflow usually shows up.
Electronic filing preflight
Check whether a scan has an existing text layer before a filing system or recipient asks for a searchable PDF. Follow the relevant court or portal's rules for the final submission.
Archive and records review
Test a scanned record locally before deciding whether it needs a full OCR pass for retrieval or review.
Sensitive document inspection
Use a browser-local report to inspect the existing text layer without sending a private scan through a converter merely for that first check.
Related questions
More questions people ask before choosing a tool.
How can I tell if a scanned PDF is searchable?
Try selecting a word or searching for a distinctive phrase. You can also create a local text-layer report with PDFTry. If nothing useful appears, the PDF may be image-only.
Does PDFTry turn a scanned PDF into a searchable PDF?
Not currently. PDFTry's OCR Scanned PDF tool reports text already available in the file. A scan with no text layer needs a true image-OCR workflow.
Will a searchable PDF always be accepted by an upload portal?
No. Portals may also set rules for file type, size, encryption, names, page order, and document content. Check the destination's instructions and review the finished file.

Best next move
Make smaller, locally
Choose a no-upload flow first. This is the strongest fit for private files because the file does not need to leave your browser.

FAQ
Check a scanned PDF for selectable text before upload questions
Can I check a PDF's text layer without uploading it?
Yes. PDFTry's OCR Scanned PDF tool creates its text-layer report in your browser and downloads it locally.
Why does my scan look clear but have no selectable text?
The PDF may contain images of pages rather than an embedded text layer. Visual clarity alone does not create searchable text.
What should I do when the local report is empty?
Use an approved full OCR workflow if the destination needs searchable text, then review the resulting PDF. PDFTry's current tool does not add image OCR to an image-only scan.
Is a text report enough to prove my filing is valid?
No. It is a useful preflight check. Follow the receiving organisation's requirements and inspect the final file before submission.
