Frequently asked questions
Are uploaded documents public?
No. Inputs are staged outside the public web directory in an isolated user or visitor workspace. Generated downloads require a random authorization token and expire automatically.
Which documents are rejected?
Empty, oversized, malformed, mismatched, unsupported or unexpectedly encrypted files are rejected before processing. Individual tools also enforce page-count, memory and runtime limits.
Will the output always look identical?
Page-management operations generally preserve original PDF pages. Rotation and watermark tools deliberately rasterize pages at a controlled resolution, so selectable text and vector content may become fixed image content.
