FAQ

Is this tool free?

Completely free, no usage limits, no signup required.

Can I reorder PDFs?

Yes, drag the PDF cards in the grid. Card order = merge order.

How many files?

Up to 20 PDFs, max 30MB each, total max 150MB.

Are encrypted PDFs supported?

Not yet. Please unlock encrypted PDFs first. We'll identify which files are encrypted.

Are my files safe?

Files are only used for merging and auto-deleted after completion.

How can I process a scanned PDF without obvious quality loss?

Start with the original scan, avoid repeated recompression, and enable any image- or OCR-friendly mode when available. After processing, preview text edges, tables, and image detail before exporting the final PDF.

Is this tool suitable for preparing PDF files for email attachments?

Yes. Email-ready PDFs usually need the right balance of file size, compatibility, and loading speed. Compress or convert first, then confirm fonts, margins, images, and page count still look correct.

What is the difference between this online PDF tool and desktop software?

Online tools are usually faster for one-off tasks and lightweight workflows because there is nothing to install. Desktop software is stronger for batch automation, complex layouts, and enterprise pipelines. For quick conversion, compression, merging, and export, online is usually the fastest path.

Do I need to sign up, download, or install anything?

Most Gotokit tools are designed to open directly in the browser without a separate install. If a tool has a quota, browser requirement, or third-party dependency, the page copy will state that clearly.
