Selected files are read and rewritten in browser memory. Merge and split modes copy PDF pages, while image-to-PDF embeds the selected raster images on newly sized pages.
Compression intentionally rasterizes each page, which can reduce scan-heavy files but removes searchable text, forms, links, annotations, and vector structure. Keep the original file until the result has been checked.
Questions
PDF Splitter FAQ
How do I enter page ranges?
Use commas between selections and hyphens for inclusive ranges, such as 1-3,5,8-10.
Does splitting alter page content?
No. Selected pages are copied into new PDF documents without rasterizing their text or graphics.
