Lower is smaller. 92% looks identical to the original.
This converter needs JavaScript. It runs entirely in your browser and nothing is uploaded.
Looking for video or audio? Those live on the video pages. Word, Excel and other documents need a server-side engine, so I don't offer them — CloudConvert handles those.
Private by design
Files are read and written on your device. The page never uploads them, so there is nothing to delete later.
No limits, no watermark
Convert as many files as you like, as often as you like. There is no queue and no daily cap.
Fast and offline-capable
Your browser does the work, so a batch finishes in seconds and keeps working without a connection.

About merge pdf
Contracts come as three attachments, the cover letter is separate from the CV, the scanner made a file per page. Merging PDFs is one of the most common document chores there is, and almost every free tool for it wants you to upload the files to a server first. For contracts, medical records, and tax paperwork that is a bad trade.
This page merges PDFs entirely in your browser. Drop the files, put them in order with the arrows, and click Merge. Every page from every file is copied into a new PDF in that order. Bookmarks and form fields are not carried across, but page content, images, and text remain exactly as they were.
There is no page limit, no daily quota, and no watermark, because there is no server doing the work.
Frequently asked questions
Can I merge password-protected PDFs?
Not while they are locked. Open the file in a viewer, save an unlocked copy with the password removed, and merge that.
Are fillable forms and bookmarks preserved?
Page content is preserved exactly, but interactive form fields, bookmarks, and links between pages are not copied into the merged file. If you need those, merge in a full PDF editor.
Is there a limit on file size or number of files?
Up to 50 files per merge, each up to 100 MB. Very large merges depend on your device’s memory since the work happens locally.
Can I merge only certain pages from each PDF?
Use the Split PDF tool first to pull out the pages you want from each file, then merge the results.
