Several PDFs into one
Merge PDF files
Combine certificates and mark sheets into a single PDF, in your order. Text stays text — and nothing is uploaded.
Why lossless matters here.
Most online mergers re-render every page, which turns a typed mark sheet into a blurry image and
can make small print unreadable at exactly the moment someone official needs to read it. This one
copies the pages across untouched. If you also need to hit a size limit, it tells you what the
clean merge weighs before offering to compress — see also

Questions
How do I merge PDFs for a government application?
Add each file, drag them into the order the portal asks for, and merge. Applications commonly want "all documents as a single PDF" — a mark sheet, a category certificate and an ID proof in one file. The order is the order you see on screen.
Does merging reduce the quality?
No. Pages are copied between documents rather than re-drawn, so text stays selectable and scans keep their original image data. That is different from most online mergers, which re-render everything.
What if the merged file is over the portal’s size limit?
Set a size limit before merging and the tool tells you the lossless size first. If that is over the limit it offers to squeeze it, and says plainly that squeezing converts every page to an image — fine for a scan, not for a typed document. You can always take the lossless file instead.
Are my documents uploaded anywhere?
No. The merge happens inside your browser. There is no upload endpoint, and the Content-Security-Policy on this site blocks the page from sending data anywhere. That matters more than usual for certificates and mark sheets.
Can it merge a password-protected PDF?
No. An encrypted PDF is refused with a clear message rather than producing a broken file. Remove the password in your PDF reader first, then merge.
