Good to know

The last file may have fewer pages. Reorder, rotate, or remove pages before export; selecting pages alone does not exclude the others.

PDF Splitter help

Split into files

Set the pages per file and download a ZIP of numbered PDFs. Borders and file labels identify each group. All remaining pages are exported, not just the selection.

Manage files

Choose files starts a batch. Replace files or dropping new files replaces it; Add files keeps the current batch. Unchanged duplicates are skipped when adding. Canceling the picker leaves your work intact. Delete removes a file or page; Clear all empties this tool. Deletes also clear edit history. Undo and Redo still work for reordering and rotation.

Select pages

Click a thumbnail to select it. Shift-click selects a range; Ctrl-click (Cmd-click on Mac) toggles individual pages. Ctrl/Cmd+A selects all; Escape clears the selection. Export includes all remaining pages unless you choose Selected pages only in Flatten PDF.

Supported files

Import PDFs, browser-readable images, Word .docx, or plain text. Save older .doc files as .docx or PDF first. Word conversion is approximate and image-based; fonts, fields, and pagination may change. For accurate layout, export a PDF from Word first.

Keep your original

Review important work before printing. PDF bookmarks, attachments, signatures, accessibility tags, links, forms, and other interactive features may not survive. Cropping and flattening are not secure redaction.

Privacy and navigation

Files are processed on your device, not uploaded or sent to ads. Only theme and import preferences are saved. Download before changing tools, refreshing, or closing: each page starts fresh, including browser Back and Forward. Clearing files releases the app's references, but browser memory cleanup is not secure erasure. Original files and downloads remain on your device.

PDF and Word libraries load from public CDNs and need internet. Photo cropping and ZIP creation use local browser features and bundled code. Ads stay in separate sandboxed frames. Privacy details.

Import settings

These settings affect new image and Word imports. Existing PDF page sizes are never changed.

Standard paper uses automatic portrait/landscape orientation and fits the entire image without cropping.
Need an exact Word layout? Save as PDF in Word first. Browser DOCX conversion can change fonts and pagination, and produces image-based pages.
