Questions
What is Gmail's limit?+
25MB per message including all attachments. Outlook.com is 20MB and many company servers are 10MB.
Are my files uploaded anywhere?+
No. Every PDFOnCall tool runs inside your browser, so the file never leaves your device. That is also why it finishes in seconds instead of waiting in an upload queue.
