No hard limit — constrained only by browser memory. 20-30 files under 20MB each usually merge smoothly; split large files into batches and merge again if needed.
Does the merged PDF have watermarks or ads?
No. aipzz PDF merge is completely free, watermark-free, with no brand stamps or promotional links. The output matches the source content exactly.
Can I reorder files before merging?
Yes. After uploading, drag to reorder, delete, or preview any file. Final page order is confirmed before the merge runs.
