What is it?PDF Version Checker is a PDFLean local analysis tool: Read a PDF's version number, page count, and encryption status to check compatibility.
TL;DR: Read a PDF's version number (such as 1.4, 1.7 or 2.0) with page count and encryption status to verify compatibility. Everything runs locally in your browser — your file is never uploaded; the version is read from the file header and does not guarantee full feature compatibility.
About this tool
Designed for the moment you need a document changed quickly and privately. Read a PDF's version number (e.g. 1.4 / 1.7 / 2.0) with page count and encryption status, to check compatibility. Processing runs locally in your browser's memory — the document is never transmitted, and closing the tab clears it completely. The workflow is deliberately short: load the file, choose the options on the page, run the operation, and save the result. Every choice is applied before the file is written, so re-running with different settings takes seconds. practical limits apply (see the on-page limits); it pairs well with the related tools linked beside this page when one step is not the whole job. Key facts — Processing: runs entirely in your browser, client-side; Access: free with no account required; File limits: see the on-page limits; Privacy: the file never leaves the device.

FAQ
Will my file be uploaded?
No. Everything runs locally in your browser — your file is never uploaded.
Are there any limits?
The version is read from the file header; it does not guarantee that every PDF feature is supported.
How accurate is the version detection?
Very accurate. The tool reads standard header markers (e.g. %PDF-1.4 / 1.7 / 2.0), page count, and encryption flags directly from document metadata for reliable results.
Can I process multiple files in bulk?
A single tool page handles one task at a time; for bulk work use the Batch Processing workflow and add this tool as a step to run a whole set at once.
Does detection modify my original PDF?
Not at all. Version checking is a client-side, read-only inspection tool that reads header metadata without modifying or overwriting your original file.
