You have 15 invoice PDFs from last month, each its own file. You need one combined PDF for your accountant, sorted by date. GekiPDF's merge tool accepts up to 20 files per run and lets you drag them into the exact order you want before combining.
The merge is lossless: pages are copied, not re-encoded, so your invoice text stays sharp and file size stays close to the sum of the originals. Mixed page sizes (A4, letter) are kept as-is. No signup, no watermark, and files are deleted from our servers after one hour.
Frequently asked questions
Can I reorder invoices after uploading?
Yes. After adding files, drag each thumbnail left or right to set the order. The final PDF follows that sequence exactly.
What happens if an invoice is larger than 50 MB?
Each file must be under 50 MB. If yours is bigger, use compress-pdf first to reduce it below the limit.
How many conversions can I do per hour?
Up to 40 merges per hour per IP address. That covers most monthly batches; if you hit the cap, wait a few minutes and try again.
