Why use a browser-based merge pdf?
Desktop PDF editors like Adobe Acrobat cost money and must be installed on every machine you use. Online mergers are free but typically upload your files to a server — a real concern when the documents are contracts, medical records, or anything confidential.
LoveMyFile merges PDFs entirely in your browser using pdf-lib, a pure-JavaScript library that reads and writes PDF structures without sending anything over the network. The combined file is assembled on your device and downloaded directly, so there is no server copy, no retention period, and no privacy policy to read.
Because nothing is uploaded, merging is also faster for large files — you skip the upload wait and the download wait. The only bottleneck is your computer's processor, which handles the assembly in seconds for typical documents.

Common issues and fixes
- The merged PDF is larger than the individual files combined.
- This is normal — the merger preserves all embedded fonts and images from every source file. If size matters, run the merged file through the Compress PDF tool afterwards to strip redundant data.
- Some pages appear rotated or upside-down after merging.
- The merger respects the rotation stored in each source PDF. Use the Rotate PDF tool first to fix orientation on the problem file, then merge again.
- I cannot drag files into the dropzone.
- Make sure your browser supports drag-and-drop (all modern browsers do). You can also click the dropzone to open a file picker as a fallback.

Frequently asked questions
How many PDFs can I merge at once?
As many as your browser memory comfortably handles, typically dozens of files. The combined PDF is assembled locally and downloaded directly, with no upload step in between.
Will the merged PDF keep bookmarks and links from the original files?
The merger preserves the page content of every source PDF. Internal links and bookmarks that point to pages within the same source file are kept; links that reference external URLs are also preserved.
Can I merge PDFs that have different page sizes?
Yes. Each source file retains its original page size in the merged output. If you want uniform page sizes, resize or crop each file first before merging.
Do I need to install anything to use these PDF tools?
No installation required. Every PDF tool is browser-native and runs on modern browsers (Chrome, Edge, Firefox, Safari) without plugins, extensions, or desktop apps.
Does this upload my file?
No. Your file stays on your device the whole time. LoveMyFile runs entirely in your browser, so nothing is uploaded to a server, queued in the cloud, or copied off your computer.
Is this free?
Yes. Every tool is free and unlimited — no account, no paywall, and no daily caps. Because the work happens locally in your browser, there are no per-file or per-page charges.
Does it work offline?
Yes. Once the page has loaded, the tools run entirely in your browser, so you can disconnect from the internet and keep working. AI-powered tools download a small model on first use and then also run offline.
