What this tool does
Set opening layout and document title preferences. 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. Image compression and PDF to JPG support up to 150 pages. OCR supports up to 30 selected pages per run. Browser memory and device performance can reduce practical limits.
Output quality and limitations
Review the preview before downloading. Some operations can change document structure: Image compression rasterizes pages, while Preserve text and vectors keeps selectable content where possible; 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.
