将多个页面合并到一张纸上
每张纸合并 2 或 4 个页面——适合讲义和草稿。
使用方法
上传您的 PDF，选择 2 合 1 或 4 合 1，然后下载结果。页面会按原始顺序从左到右、从上到下排列。
多合一排版适合什么场景？
用更少的纸打印讲义、草稿或审阅稿——2 合 1 会把两个原始页面并排放在一张纸上，4 合 1 则以网格形式容纳四个页面。
多合一排版会改变阅读顺序吗？
不会——页面会按原始顺序从左到右、从上到下排列，因此纸张的阅读顺序与原文档一致。
Will N-up make the text smaller and harder to read?
Yes — since more original pages share one sheet, each shrinks proportionally. It's best for draft/reference copies, not documents that need to stay full-size legible.
Can I do 6-up or 9-up, more than 4 pages per sheet?
Not currently — this tool supports 2-up and 4-up layouts.
Does N-up add borders between the combined pages?
Pages are placed edge to edge in a grid without added borders or gutters, matching the original page boundaries.
Is this the same as booklet printing or imposition for folding and stapling?
No — this just places pages in a simple grid, in their original reading order. It doesn't reorder pages for saddle-stitch folding the way dedicated booklet-imposition tools do. If you need sheets that fold into a bound booklet, you'll want a tool built specifically for that.
Can I choose a different output sheet size, like A3 or Letter?
Not right now — every sheet comes out as A4, regardless of your original page size. There's no option to target A3, Letter, or Legal.
Does 2-up rotate the sheet to landscape?
No — the sheet stays A4 portrait. For 2-up, your two pages sit in narrow columns side by side rather than spread across a wide landscape sheet.
What print settings should I use for the output?
Print at 100% / actual size, and turn off "Fit to page" or "Shrink oversized pages" in your print dialog. The output is already sized to full A4 sheets, so scaling it again just shrinks everything further.
