Global Performance
Cloud infrastructure ensures fast processing and low latency across worldwide locations.
Flexible Output
Separate pages individually or create custom page groups with our powerful API.
Customizable Parameters
Fine-tune your automation with these powerful conversion options
File
File Supported formats: .pdfFile to be converted. Value can be URL or file content.
Password
StringSets the password to open protected documents.
Mode
Collection Default: pagecountSelects how the document is split. pagecount cuts consecutive chunks whose sizes follow Value - a comma-separated sequence repeated until the document ends (e.g. Value=5 on a 10-page file gives two 5-page files; Value=3,2 gives 3, 2, 3, 2, ...; empty Value means one file per page); ranges emits one file per page or range listed in Value (e.g. 1-3,5,7-9 gives three files); singlepages extracts each page listed in Value as its own file (e.g. 1-2,5 gives three single-page files: page 1, page 2, page 5); text starts a new file at every page whose text matches the Value regular expression; bookmark splits at each bookmark (Value is ignored).
Value
StringThe argument for the selected Mode: a page-count sequence (pagecount), a page or range list (ranges, singlepages), or a regular expression (text). Ignored when Mode is bookmark. For pagecount an empty value produces one file per page.
MergeOutput
Bool Default: FalseWhen set to true, all files produced by the split, regardless of the split method used, are merged into a single PDF named merged.pdf. By default (false) the API returns each split part as a separate PDF.
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.
