Merge PDF files into one document in the order you choose: drop them together, drag the list into place, and download a single combined PDF. Each row shows the file’s first page and its page count, so three similar-looking scans are easy to tell apart. It suits the everyday jobs: a job application with a CV, cover letter and certificates, or a year of statements for an accountant. Pages are copied across intact, not re-rendered, so text stays sharp and selectable. Up to 100 files or 2 GB per merge, combined on your own device with nothing uploaded.
How it works
- Drop two or more PDFs at once. Each one is checked as it loads, and a password-locked file is flagged in the list rather than silently skipped.
- Drag the rows into order, or use the arrows. Click a thumbnail to page through that file before you commit, and remove any you added by mistake.
- Press Merge & download. The result line confirms how many files and pages went in, and the size of the merged PDF.
Questions
- Can I combine PDFs in a specific order?
- Yes: the order of the list is the order of the output. Files start in the order you dropped them; drag a row, or use its up and down arrows, to move it. The first file’s pages come first, then the second file’s, and each file keeps its own page order inside the merged PDF.
- Why can’t I merge a password-protected PDF?
- An encrypted PDF cannot be read without its password, and this tool does not ask for one or try to get around it. The file is marked with an error and the merge waits until you remove it. Open it in an app that knows the password, save an unlocked copy, and drop that instead.
- Is there a limit on how many PDFs I can merge?
- 100 files or 2 GB in total per merge, whichever you reach first. Both limits are checked before anything runs, and the message names the one you hit. For more than that, merge in two rounds: combine the first batch, then merge that result with the rest.
- Does my file get uploaded?
- No. The models and all processing run inside your browser on your own device. You can verify this yourself: open your browser’s DevTools, watch the Network tab, and process a file: there are no uploads. After the first visit most tools also work fully offline.
- Is merge/split lossless?
- Yes. Merging, splitting, reordering and rotating copy pages intact: text stays selectable, links keep working, quality is untouched. Only the compress pages re-encode content, and they say so.
- How strong is the password protection?
- Without the password the file cannot be opened. The cipher follows the PDF’s own version: AES-128 for PDF 1.6 and 1.7, and the older RC4 cipher for other versions. Choose a real password: the encryption is only as strong as it.
- Can it compress any PDF to 100 KB?
- No, and it will not pretend to. Image-heavy pages compress well; a born-digital text PDF may already be near its floor. The tool reports the size it achieved rather than silently overshooting.
