A Government Portal Wanted One File. I Had Seven. Here Is What I Built.

The scholarship form was straightforward enough. Fill in your details, attach your documents, submit. Standard government portal stuff.
Except for one requirement buried in the instructions: "Upload all documents as a single PDF file."
I had seven separate files. My application form. Mark sheets. Caste certificate. Income certificate. Bank details. Photograph. Aadhar copy. All individual PDFs and JPGs sitting in different folders on my phone.
Combining them into one file — I had absolutely no idea how to do it.
The Search That Went Nowhere
I searched online for how to merge PDF files for free. The results looked promising. I clicked the first one. Uploaded my files. The tool processed them. I clicked download.
Sign up to download your merged PDF.
I tried the next result. This one worked — but added a watermark across every page. A scholarship application with "PDF24 — Free Trial" stamped on each page is not going to impress anyone reviewing it.
Third site. Uploaded all seven files. The site processed for a few minutes, then showed an error. My files were gone. I had to start over.
I downloaded an app. It merged the files but the output was 47MB — the portal had a 5MB limit. The app had a compression feature, but that was behind a premium subscription.
"I spent more time trying to merge seven files into one than I had spent filling out the entire scholarship application. A task that should take thirty seconds was taking hours."
Why This Problem Exists Everywhere
After going through this, I realized the problem was not unique to me. Government portals across India — scholarship applications, job applications, college admissions, scheme enrollments — almost all of them have single-file upload requirements. And almost nobody knows how to merge PDFs easily.
The tools that exist either:
Require you to create an account before downloading
Add watermarks to the output
Upload your files to their servers — a serious privacy concern for official documents
Charge for basic features like downloading or compressing
Fail silently and lose your uploaded files
Building the PDF Merger
I already had several tools running on TaskGuru. Adding a PDF merger was something I kept putting off because merging PDFs is technically more complex than it sounds — you need to handle different PDF versions, page sizes, embedded fonts, and image quality.
But after my own scholarship form experience, I stopped putting it off.
The tool I built uses pdf-lib — a JavaScript library that runs entirely in your browser. Your files never get uploaded to any server. The merging happens locally on your device, which means:
Complete privacy
Your certificates, ID proofs, and financial documents stay on your device. Nobody else sees them.
No file size surprises
You can see the output size before downloading and decide if you need to compress it separately.
No watermarks
The output PDF is clean. No trial stamps, no service branding, nothing except your actual content.
Drag to reorder
You can drag your uploaded files into the correct order before merging — so your documents come out exactly as you need them.
Who Needs This Tool Most
If you have ever faced any of these situations, this tool was built for you:
Students submitting scholarship or college applications on government portals
Job seekers who need to combine a CV, cover letter, and certificates into one file
Professionals submitting proposals or reports as a single document
Anyone dealing with government forms that require multiple documents in one upload
Small business owners combining invoices, receipts, or contracts for clients
The scholarship form situation from my own experience — that exact problem — is what this tool solves. In about thirty seconds, without an account, without paying anything, without your documents touching anyone else's server.

How do I merge PDF files for free?▼
Go to TaskGuru's free PDF merger, upload your PDF files, arrange them in order, and click Merge. The combined PDF downloads instantly. No signup, no payment, no watermark. Everything runs in your browser — your files never get uploaded to any server.
Can I merge PDF files without installing software?▼
Yes. TaskGuru's PDF merger works entirely in your browser — no software download or installation required. It works on Windows, Mac, Android, and iOS using Chrome, Safari, Firefox, or Edge.
Is it safe to merge sensitive documents online?▼
With TaskGuru, yes — because your files never leave your device. The merging happens locally in your browser using JavaScript. Most other online PDF mergers upload your files to their servers, which is a serious privacy risk for official documents like certificates, ID proofs, and financial records.
How many PDF files can I merge at once?▼
TaskGuru's free PDF merger supports merging multiple PDF files in a single session with no file count limit. You can drag and drop to reorder the files before merging.
Why do government portals ask for a single PDF file?▼
Government portals typically have a single file upload field to simplify document management on their end. Instead of processing multiple attachments, they require everything — application form, certificates, ID proof, photographs — combined into one PDF file.
