Frequently Asked Questions

How many PDFs can the merge tool combine at once?
Multiple files — 20 or fewer is recommended for smooth performance. Order follows file selection and can be adjusted by dragging; great for contracts, reports and scans.
How do I merge multiple PDFs into one?
Upload the PDFs, drag to reorder, click Merge, and the combined file downloads automatically. Everything runs locally; nothing uploads.
Will merged PDFs garble or lose pages?
No. Standard PDF merging preserves every page, layout, image and font — no lost pages, garbling or format changes.
Is online PDF merging safe?
Safe. All processing runs locally in your browser; files never upload, suitable for contracts, bids and theses.
Is the PDF merge tool free?
Yes — no registration, no file limits, no watermark. Built for office workers, students and admins with frequent document work.
Are there file size limits?
Keep single files under 100MB for smooth processing. Larger files may work with enough browser memory; compress first for very large sets.
Can I merge different file formats?
Currently PDF-to-PDF. To include images or Word files, convert them to PDF first with our image-to-PDF tool.
Does merging compress PDF quality?
No. Merging preserves original page quality and clarity with no compression — output matches source quality.
