Combine PDF files into one document
Job applications, visa files, tax paperwork and invoices usually have to go in as a single PDF. Drop in all your files, put them in order, and you'll get one clean document with every page intact — text stays selectable and images keep their original quality.
The number next to each file shows exactly where it lands in the final PDF, so there's no guessing before you download.
Merge password-protected PDFs
This is where most merge tools fail: add a locked bank statement and you just get an error. Here, a password box appears next to that file. Type the password once and it's merged with the rest — and the combined PDF opens without a password.
No sign-up, no watermark, no daily limit
You can merge up to 50 files (about 300 MB) at a time, with no page limit and nothing stamped on your pages. Need more than that? Merge in batches, then merge the results. Merging also keeps you within the file limits of AI study tools; see NotebookLM vs ChatGPT.
Because merging happens on your device, there's no upload wait either — even large files are combined in a few seconds.
