Remove Watermark PDF Ruby Overview
Automatically remove text watermarks from PDF documents. AI detects repeated overlay text across pages — status stamps, evaluation marks, ownership notices, and similar text annotations — and removes them cleanly without affecting surrounding content. Only the detected text watermark is removed; other content remains unchanged. Supports watermarks in any language, with an optional hint for unusual cases.

File
File Supported formats: .pdfFile to be converted. Value can be URL or file content.
Password
StringSets the password to open protected PDF.
AiDetection
Bool Default: TrueUse AI to detect and remove text-based watermarks. When disabled, only structural watermarks embedded in the PDF are removed.
WatermarkHint
StringOptional description of the watermark to help the AI detect and remove it more accurately. Useful when the watermark contains specific text, logos, or other identifiable characteristics.
PageRange
String Default: 1-2000Set page range. Example 1-10 or 1,2,5.
StoreFile
Bool Default: FalseWhen the StoreFile parameter is set to True, your converted file is written to ConvertAPI’s encrypted, temporary storage and made available via a time-limited secure download URL, valid for up to 3 hours. After this period, the file is permanently deleted.
When StoreFile is set to False, conversion happens entirely in-memory. The raw file bytes are streamed back in the API response without touching disk or external storage, ensuring maximum security and zero persistence so that only you can access the content.
