Most student portals cap each upload at a certain size and often require a single PDF for the whole assignment. If you have multiple scans, screenshots, or exported files, merge them into one document before submitting. GekiPDF lets you combine up to 20 files per run, drag to reorder pages, and keep original quality—no re-encoding, so your text stays sharp.
Your files stay private: no signup needed, no watermark added, and uploaded files are deleted after one hour. Each file can be up to 50 MB, and you get 40 conversions per hour per IP address. That's enough for most students' needs—just drag your PDFs in order, hit merge, and download the combined file ready for the portal.
Frequently asked questions
Can I merge more than 20 PDFs?
No, the tool accepts up to 20 files per run. If you have more, split them into two merges and then combine those results (each under the limit) in a second pass.
Will merging reduce the quality of my pages?
No. The tool copies pages without re-encoding them, so text and images remain exactly as they were. Mixed page sizes (e.g., A4 and letter) are kept as-is.
How long do my files stay on the server?
Uploaded files are deleted after one hour. You can download your merged PDF immediately after processing; there is no account or storage on our side beyond that time.
