PDF Merge up to 20 files
Combine several PDFs into one document without uploading them anywhere. The merging library loads only when you press Merge — the page itself ships no PDF code.
No files yet. Add two or more PDFs and they will be merged in the order shown.
Questions we get a lot
Is there a file size limit?
Up to 20 files, 100 MB each. The real limit is your device memory: a stack of 100 MB files is read into the tab all at once, and a phone will give up earlier than a laptop.
Does merging re-compress the pages?
No. Pages are copied into the new document as they are — same resolution, same embedded fonts, same file weight. If two input files contain the same font, both copies are kept.
What happens to bookmarks and form fields?
Page content is copied faithfully. Document-level bookmarks (the outline) and interactive form fields are not carried over — this is a page merger, not a PDF editor.
Why was my password-protected file skipped?
Encrypted PDFs are refused rather than silently merged with blank pages. Open the file in a reader, save an unencrypted copy, then add it again.
Will it handle scanned PDFs?
Merging works on any PDF regardless of content. Text extraction and OCR are separate tools and are not part of this one.
