A recruitment portal with one box labelled Educational Certificates expects a single file, while the certificates sit in your downloads as separate PDFs: the tenth-class marksheet, the twelfth, the degree, a caste or income certificate. This page joins those PDFs into one document, page after page, in the order you set, so the upload happens once instead of after a hunt for boxes that do not exist.
Add the files, arrange them with the up and down arrows, and press Merge. Every page of every file is copied into the new document. A landscape page stays landscape, an A5 page stays A5; nothing is scaled to match its neighbours. The size on the result card is close to the sum of the files that went in.
How to use it
- Select two or more PDFs at once, or add them one at a time.
- Use the arrows to put them in the order the pages should follow; the × button removes a file from the set.
- Press Merge. The result card shows the page count and the combined size.
- Download, open the file once to check the order, and upload.
What is kept and what is not
Page content, fonts, images and page sizes are carried across exactly as they were. What does not survive is the interactive layer: fillable form fields, and the bookmarks panel that some long documents have, are not copied into the merged file. If one of your PDFs is a form you have typed into, print it to PDF or flatten it first so the typed answers become part of the page artwork.
File size after merging
Merging does not compress anything, so expect the combined file to weigh roughly what the parts weighed together: four scanned certificates of 400KB each give a document of about 1.6MB. That is where portal caps bite, because limits between 100KB and 1MB are common on Indian recruitment portals for scanned certificates in PDF form. If the merged file lands above the cap, open it in the compress-pdf tool, which brings a multi-page scan down in one pass rather than certificate by certificate.
Frequently asked questions
- Is there a limit on how many PDFs I can merge?
- No fixed count. The practical limit is memory: a dozen scanned certificates of a few megabytes each merge without trouble on a recent phone, while hundreds of pages of heavy colour scans may stall. Merge such a set in two or three batches, then merge the results.
- Why did the typed answers in my form disappear?
- Form fields are not carried over; the merged file holds the page artwork but not the layer where typed text lives. Flatten the form first: open it, choose Print, pick Save as PDF as the printer, and merge that printed copy.
- Can I merge JPG photos together with PDFs?
- Not directly, since this tool accepts PDFs only. Turn the photos into a PDF first with the image-to-pdf tool and add that to the list. The merge-images tool is the equivalent for stitching pictures into one picture rather than one document.
- Can I make every page the same size?
- Not during the merge; each page keeps its own dimensions. If a portal preview looks untidy because one certificate was photographed as a tall, narrow page, convert that one to an image, rebuild it with the image-to-pdf tool on A4, and merge the A4 version instead.
