Add Bookmarks from Headings.

When the operation supports page ranges, SnapPDF applies the change only to the selected pages. Tools without page controls process the whole PDF.

SnapPDF keeps the existing page order unless the selected operation is designed to reorder, split, or combine pages.

Page-level operations usually preserve the original page content. Output can change if the operation rasterises, rotates, crops, or rebuilds pages.

Batch support depends on the endpoint. If this tool accepts multiple PDFs, SnapPDF processes them in upload order and rejects unsupported batches.

SnapPDF processes the PDF only for the requested page operation. Client-side tools keep files in your browser; server-side tools delete jobs after download.
