Merge PDF files
Combine multiple PDFs into a single document — reorder before merging. 100% in your browser.
This tool runs entirely in your browser. Your file is never uploaded.
よくある質問
Is there a limit on how many PDFs I can merge?
No. HonestPDF has no file-count or daily limits. Merging happens in your browser, so the only limit is your device's memory.
Will the merged PDF have a watermark?
No. HonestPDF never adds watermarks to your documents.
Are my files uploaded to a server?
No. All local tools process your file inside your browser using WebAssembly. You can verify this in the Network tab of your browser's developer tools.
Do I need a subscription?
No. Local tools are free without limits. AI features use one-time credit packs whose balance never expires.
