Perguntas Frequentes
- Is it safe to merge PDFs online?
- Yes. Unlike most online PDF tools, this one runs entirely in your browser. Your PDF files are never uploaded to any server. All merging happens locally using pdf-lib JavaScript library.
- Is there a file size limit?
- There's no hard limit since processing happens in your browser. However, very large PDFs (100+ MB) may be slow depending on your device's memory. For most documents, merging is instant.
- Can I reorder PDFs before merging?
- Currently, PDFs are merged in the order you select them. For custom ordering, use our PDF Page Reorder tool after merging, or select files one by one in your preferred order.
- Does this replace Adobe or iLovePDF?
- We are a lightweight, privacy-first merge. We do not offer every feature of desktop editors or large suites — only client-side merge with no account.
