PDF combiner

A PDF combiner is an online tool designed to merge multiple separate PDF files into a single document. Rather than managing scattered invoices, reports, or project files, you use this tool to merge them into one organized flow. This process is essential for streamlining digital administration, ensuring that related documents stay together when shared or archived.

Unlike our document creator, which helps you draft and format original content from scratch, Wixel’s free PDF combiner focuses strictly on the organization of existing files.

Why this matters: Sending a single attachment is often more professional than sending five separate emails. It reduces the risk of a recipient missing a file and ensures the narrative of your document follows the specific order you intend.

Pro-Tip: Use Wixel’s free PDF combiner to archive monthly records. Merging four weekly reports into one monthly file reduces clutter and simplifies file retrieval later.

To combine PDF files, the process involves uploading your source documents, arranging them, and saving the new master file. Wixel’s interface allows you to handle this manually or via AI chat.

Step-by-step guide:

1. Upload: Navigate to the tool and upload your PDFs. You will need to sign in to access the workspace.

2. Add files: If you need to include more documents after your initial upload, simply click "PDF Tools" then "Combine PDFs" to attach them.

3. Arrange: Use the visual Pages Panel to drag pages into your preferred sequence.

4. Merge: Once organized, click "Share" then "Download" to save the unified document.

If you’re applying for a job, you can draft your CV using our resume builder, export it, and then use our PDF combiner to attach your cover letter and portfolio. This ensures the recruiter receives your full application in one tidy package.

Yes, you can merge PDFs online without a subscription. Wixel offers a free tier that allows users to access essential tools, including the PDF combiner, at no cost. This plan is designed to give users a chance to explore and trial Wixel, making it ideal for performing quick admin tasks.

While the “Wixel Free” plan includes access to the entire platform, it is governed by a credit system for AI-generated tasks, providing a number of free credits every week. This ensures that while standard merging is accessible, you also have the opportunity to test AI features—like generating images or video clips.

If you’re planning an event, for example, after designing a card with our invitation maker, you might merge it with a map and an itinerary PDF to create a complete guest information packet.

Our PDF combiner is completely free. Merging, reordering, and organizing files—whether done manually or via AI chat—are non-generative actions, meaning they do not use any credits.

Credits are only deducted for generative tasks, like asking the AI to write new content. This allows you to combine professional assets, like our resume templates, with your other documents without worrying about usage limits.

When you use our PDF combiner, security is managed through account isolation and encryption. Unlike basic web tools that process files anonymously, Wixel requires you to sign in to open your file. This ensures that your documents are locked to your private account rather than being exposed in a temporary, public-facing session.

Once uploaded, your files are fully encrypted and stored securely in your personal project area. This allows us to keep your files accessible indefinitely—so you can return to annotate or edit them on any device—while ensuring they remain private and readable only by you.

The ability to combine PDF files effectively relies on precise page ordering. Wixel provides a visual "Pages Panel" at the bottom of the screen, giving you granular control over the document structure.

How it works:

• Visual grid: All pages from your uploaded PDFs are displayed as thumbnails.

• Drag and drop: You can click and hold any page to move it to a new position in the sequence.

• Delete: If a specific page is irrelevant (e.g., a blank page from a scanned invoice), you can quickly remove it.

The workflow is similar to our video maker, where you arrange clips on a timeline to tell a story. Here, you are sequencing static pages to ensure the final document flows logically from introduction to appendix.

Yes, you can combine PDF files that have different dimensions. It is common to merge an A4 text document with a letter-sized chart or a smaller receipt scan. The combiner compiles these pages into a single file, preserving the original dimensions of each page.

Why this happens: PDFs are container formats that support mixed page sizes within a single document. This means you don’t need to manually resize every page before uploading.

While the file will technically function with mixed sizes, it may look disjointed to the reader. To maintain a professional appearance—similar to ensuring consistency with our social media templates—we recommend checking the Pages Panel. If a page looks drastically out of scale, you may want to adjust it separately before downloading.

The process of merging PDFs is designed to be quick. For standard text-based PDFs, the combination happens almost immediately after you click “Merge”.

Factors influencing speed:

• File size: Merging high-resolution scans will take longer than simple text documents.

• Page count: A 100-page report requires more processing time than a 3-page contract.

• Connection: Your upload speed plays a role in how quickly the source files reach the workspace.

Just as our background remover isolates subjects in moments, the PDF combiner is built to minimize waiting time. Once the files are uploaded, the actual merging action typically completes without a significant delay, allowing you to download your file and move on to the next task.

To merge PDF files while maintaining high visual fidelity, it is crucial to ensure your source files are high quality before uploading. The combiner itself creates a lossless container—it doesn’t degrade the text or images during the merging process unless you specifically choose to compress the file later.

Best practices:

• Source material: Avoid using screenshots or low-resolution scans if possible.

• Vector text: Use PDFs generated from text editors (like Word or Docs) rather than flattened images, as these remain crisp at any zoom level.

Pro-Tip: If one of your PDFs contains a blurry scan, the combiner cannot fix it. In such cases, you might first use our image enhancer to improve the clarity of the original image file, convert that image to PDF, and then merge.

Yes, our PDF combiner is accessible via mobile browsers, allowing you to manage documents on the go. The interface is responsive, meaning you can upload files from your device’s storage, rearrange pages, and download the merged PDF directly to your phone or tablet.

Mobile workflow:

1. Open the Wixel PDF Combiner in your mobile browser.

2. Tap to upload files from your "Files" or "Downloads" folder.

3. Use touch gestures to reorder pages in the Pages Panel.

4. Download the merged file to share via email or messaging apps.

This capability is particularly useful for remote work or quick admin tasks. Just as you might use our Instagram story templates to create mobile-first content, our mobile PDF combiner allows you to handle document admin without a desktop.
