Where do attachments show up?
Adobe Acrobat and Reader show attachments in the paperclip panel, Firefox and Chrome in their attachments sidebar, and most PDF apps have a similar list.
Attachments are part of the PDF file, so it gets bigger by their size. Some email systems block certain attached file types inside PDFs, like .exe.
Tip: Attach the original spreadsheet to a report so readers can check the numbers.
Your files stay on your device
Most online PDF sites upload your documents to their servers. Aleynray Ai does the work inside your browser instead, on your own computer or phone.
Nothing is sent anywhere, so contracts, bank statements, IDs and medical forms stay private, and there is no waiting for uploads.
