Upload your PDF files, drag to arrange them in the order you want, then click Merge. Download the single combined PDF. Processing happens entirely in your browser — your files are never uploaded to any server.
The output preserves all content from each source file — text quality, image resolution, embedded fonts, and page dimensions remain as they were in the originals. Each source document becomes a section of the merged PDF in the order you specified.
Job applications. Combining a CV, cover letter, portfolio samples, and reference letters into a single file makes it easier to submit through employer portals that accept one attachment, and ensures the hiring manager receives everything together.
Financial record keeping. Merging monthly bank statements, invoices, or receipts into a single annual document simplifies storage and makes year-end accounting reviews faster.
Scanned document assembly. When a multi-page document is scanned in separate batches — because the document was too thick for one scan run — merging reassembles it into a single file.
Report assembly. Building a presentation pack from sections created in different applications (cover page from Canva, data pages from Excel, narrative from Word) by converting each to PDF first, then merging.
Submission packages. Many government portals, university systems, and legal submission platforms require all supporting documents in a single PDF. Merging before uploading avoids repeated attachment uploads.
Text content and searchability, image resolution, embedded fonts, page dimensions and orientation, hyperlinks within each document, and table structure are all preserved in the merged output. Each source PDF's page content is incorporated exactly as it appears in the original.
Interactive form fields become flattened visual content in the merged output — they appear correctly but are no longer editable as interactive fields. Document-level metadata (title, author, keywords) defaults to the merged file rather than any source document values. Bookmarks and outlines from source documents may not transfer depending on how they were structured.
Consistent page size. If your source PDFs use different page sizes (A4 and Letter, for example), the merged output contains pages of different sizes. This is technically valid but can look inconsistent when printed or presented. For a uniform result, export all source documents at the same page size before merging.
Remove passwords first. Password-protected PDFs cannot be merged directly. Use the Unlock PDF tool to remove restrictions, then merge. Re-apply password protection to the merged result if needed using the Protect PDF tool.
Compress after merging. Large merged files — especially those combining image-heavy source PDFs — can exceed email attachment limits. After merging, run the result through the Compress PDF tool to reduce size before sharing.
Is there a limit to how many files I can merge?
No fixed limit. Very large merges may be constrained by your device memory, but for most everyday use — a dozen files totalling under 100MB — there are no restrictions.
Does the order of files matter?
Yes. The first file in the list becomes the first section of the merged PDF. Drag items in the upload list to reorder before merging.
Can I merge password-protected PDFs?
Remove the password from each file using the Unlock PDF tool first, then merge. Re-apply protection to the result using Protect PDF if needed.
Will the merged PDF be searchable?
Yes, for all source PDFs that contained searchable text. The text layer from each source document is preserved in the merged output.
Are my files uploaded to a server when merging?
No. The merge operation runs entirely in your browser. Your PDF files are read locally and never transmitted to any external server. You can verify this by monitoring your browser's Network tab during the merge.
Can I merge more than two PDFs at once?
Yes. Add as many files as needed in one session. All selected files are merged into a single PDF in the order shown in the file list.
Rifix Merge PDF combines multiple PDF documents into a single file entirely within your browser. No server upload, no registration, no file size limits. Simply add your PDFs, arrange the order, and download the merged result in seconds.
Merging PDFs is useful for combining chapters of a report, joining invoices for a monthly statement, assembling a multi-part tender document, or collecting signed contracts into one archive. Rifix handles all of this without sending a single byte of your documents to a remote server.
Add your PDF files — Click "Add PDFs" or drag and drop multiple files. You can add as many documents as needed.
Arrange the order — Drag and drop files in the list to set the order they will appear in the merged PDF.
Click Merge PDF — The files are combined instantly in your browser.
Download — Save the merged PDF to your device. The original files are untouched.
There is no hard limit — you can add as many files as your browser can handle in memory. For very large merges (50+ files or very large documents), we recommend merging in batches.
Yes. Rifix uses PDF-lib to perform the merge, which preserves page content, fonts, images, and embedded elements from each source file. Interactive form fields and links are retained where possible.
Password-protected PDFs must be unlocked first. Use the Rifix Unlock PDF tool to remove the password, then merge the unlocked files.
Yes. Rifix Merge PDF is completely free. There are no watermarks added to the output, no sign-up required, and no subscription needed.
Never. All merging happens locally in your browser. Your PDFs are not transmitted to any server at any point. This makes Rifix safe for merging confidential documents such as legal contracts, medical records, or financial statements.
After merging, use the Rifix Arrange Pages tool to reorder individual pages within the combined document. You can drag pages into any order before exporting the final PDF.
There is no set limit. You can merge 2 files or 50+ files. The practical limit is your browser's available memory. For very large batches, merge in groups of 20-30 files.
Yes. Drag the file entries up or down in the list to reorder them before merging. The final document follows the order shown.
You need to unlock password-protected PDFs first using Rifix Unlock PDF, then add the unlocked files to the merge.
The merged file is approximately the sum of all input files. If the result is too large, use Rifix Compress PDF after merging to reduce the size.
