PDF questions
Privacy, limits and what the workshop can and cannot do.
Are my PDFs uploaded to a server?
No. Both tools in the PDF workshop read, merge, split and write files with JavaScript running in your browser. Your documents are never sent to simplytools.us or a third party.
Which part should I use: merge & split or PDF maker?
Use merge & split to combine PDFs or extract exact page ranges. Use the PDF maker to add images, reorder whole files or add optional page numbers.
How do I extract pages from a PDF?
Open the merge & split section, add one PDF and enter pages or ranges such as 1-3, 5, 8-10. You can produce one combined PDF or a separate file per group. The original is never changed.
Can I add JPG or PNG images to a PDF?
Yes. The PDF maker accepts PDF, JPG and PNG files and can mix them in one document. Images are fitted onto A4 or US Letter pages.
Why can't I open a password-protected PDF?
Encrypted PDFs cannot be read without the password, and these tools do not ask for one. Remove the password in a trusted PDF app first, then try again.
Is there a file size limit or a watermark?
Each file can be up to 100 MB, and the tools are limited by your device's available memory. There is no watermark; page numbers are optional.
Which PDF format should I use for archiving?
Use PDF/A only when a records policy or recipient requires it. For everyday sharing and editing, a standard PDF is usually the better choice.
Keep the original files until you have checked the download. Closing the tab clears the working session.
