Drop several images at once for batch processing
Up to 50 MB per file
Combine several PDFs into a single document in the order you choose — scanned IDs, an invoice plus its receipts, a contract and its appendices — so you can send or upload one clean file instead of a pile of attachments. JustFileKit merges entirely inside your browser, so nothing is uploaded to a server and no copy of your documents is left behind.
Three steps: drop in all your PDFs at once, reorder them in the list, then process and download the merged file. Every page keeps its original content and quality because nothing is re-encoded — text stays selectable, images stay sharp. You can merge up to 50 files at once, with a 50 MB limit for each file.
Frequently asked questions
- Can I control the page order?
- Yes. Once you drop the files in, they appear as a list you can rearrange. The final PDF follows that list from top to bottom.
- How many PDFs can I merge at once?
- Up to 50 PDFs per job, with a 50 MB limit for each file and no daily usage cap.
- Do my files get uploaded?
- No. Merging happens locally in your browser and your documents never leave your device, which makes it safe for contracts, IDs, and anything else you wouldn't want sitting on someone's server.
- Will the quality drop after merging?
- No. Merging just stacks the existing pages into one file without re-encoding them. Text stays selectable, images keep their original resolution, and the file size is roughly the sum of the originals.
