Split PDF
Select a PDF or drag it onto the card to load page thumbnails.
Click thumbnails to select pages — shift+click for a range. Drag selected pages in the strip below to reorder.
Click a selected page to open the annotation preview, then use pen, highlighter, or eraser. Adjust stroke width with the slider. Double-click a selected page for full-screen annotation. All marks export into the output PDF.
Or type pages like 1,1,3-5,7-2 or "all". Optionally set an output filename. Click Extract Pages to download.
Merge PDFs
Select or drag multiple PDFs onto the card. Each file shows a first-page preview and page count.
Drag items or use ▲/▼ to reorder. Optionally set an output filename. Click Merge Files to download.
Tips
Drag files directly onto either card instead of using the file picker.
The active card expands to full width; collapsed card shrinks to a narrow tab — click it to switch.
