What this tool does
Check file properties, sharing risks and basic accessibility in one report. It runs locally in your browser so the selected document is not uploaded for processing.
Privacy and security
Your file stays on your device during processing. We do not collect PDF contents, filenames or text entered into tool settings. Keep your original file until you have checked the result.
Supported files and limits
Use a valid, unencrypted PDF up to 50 MB total. Merge PDF and Images to PDF accept up to 100 files. Compression and PDF to JPG support up to 150 pages. Browser memory and device performance can reduce practical limits.
Output quality and limitations
Review the preview before downloading. Some operations can change document structure: compression rasterizes pages, PDF to text needs selectable text, and interactive forms, links or signatures may not survive every transformation.
Example use cases
- Prepare a smaller document for email or online submission.
- Organize pages before sharing a final copy.
- Finish a quick document task without creating an account.

Questions & answers
What does PDF Check include?
One report contains file and sharing details plus accessibility signals such as document title, language, structure tags and selectable text.
Is this a security audit or accessibility certification?
No. These basic checks cannot verify reading order, contrast, alternative-text quality or signature validity. Review those separately.
Where do my files go?
Your files stay in your browser. PDF processing runs on your device, and file contents are not uploaded to a server. Closing the page clears the current workspace.
