Frequently asked questions
Is my PDF uploaded?
No. Processing happens locally using the pdf-lib/pdf.js libraries loaded into your browser.
Is there a size limit?
Files over 100 MB are rejected because very large PDFs can exhaust browser memory.
Does this change my original file?
No. A new file is generated and downloaded; your original file on disk is untouched.
