Merge & Split Tools
Joining documents and cutting them apart are the two jobs that come up before almost anything else. Every tool here runs in your browser, so the files never travel anywhere and the combined output is written once, locally, at full quality.
- Combine whole documents, chosen page ranges, or a mix of PDFs and images
- Cut at fixed intervals, at explicit ranges, or all the way down to one page per file
- Build a table of contents and drop the cover sheet again in a single pass

Merge & Split FAQ
Will merging reduce the quality of my documents?
No. Merging copies the original page objects across unchanged, so text stays selectable, images stay sharp, and nothing is re-encoded. If a tool re-renders your pages to images you would notice the file size jump and the text stop being selectable; none of the merge tools here do that.
What is the difference between splitting into single pages and splitting at ranges?
Single-page splitting gives you one file per page, which is what you want for redistributing a long document. Range splitting keeps contiguous blocks together and is better when you are cutting a report into chapters or pulling a section out of a manual.
Is there a file size limit when I merge many documents?
Each input is capped at 10 MB. A merge that would produce something larger than the 10 MB output ceiling is reported before anything is written, so you can split the job into smaller groups and merge the results.
