常见问题
What can I do with the PDF Multi Tool that the single-purpose tools can't?
It puts merging, reordering, rotating, duplicating, deleting, inserting, and splitting in one page grid, so you can do several of them in a single pass without downloading and re-uploading between steps. Every action is covered by undo and redo, so you can experiment before you export.
How do I combine pages from several PDFs into one document?
Upload all the source files and their pages appear together in one grid, in upload order. Drag pages into the order you want, delete the ones you don't need, and click Export PDF to download the result as a single file.
Can I add images as pages?
Drop JPG, PNG, WebP, HEIC, TIFF, BMP, GIF, or SVG files alongside your PDFs and each image becomes a page you can move, rotate, or delete like any other. Blank A4 pages can also be appended with the Add Blank Page button.
How do I split one PDF into several files?
Click the scissors icon on a page to place a split marker after it; a dashed line shows where the document will be divided. Export then produces split-documents.zip containing document - 1.pdf, document - 2.pdf, and so on.
Does rotating pages here reduce quality?
No. Rotation is stored as a page attribute in 90-degree steps rather than re-rendering the content, so text, vectors, and images are untouched. For angles other than 90, 180, or 270 degrees, use Rotate by Custom Degrees.
Can I export only some of the pages?
Tick the checkboxes on the pages you want and use Download selected to get just those pages as selected-pages.pdf. The workspace stays as it is, so you can keep working and export the rest later.
What happens to bookmarks when I export?
The export rebuilds the document page by page, so bookmarks from the source files aren't carried into the new PDF. Page content, including text and images, is copied as-is.
Are my PDFs uploaded when I use the Multi Tool?
No. Page thumbnails are rendered and the final PDF or ZIP is assembled in your browser, and damaged files are repaired locally before loading too. Nothing you drop into the grid leaves your computer.
