One file, many pages
Merge PDFs when the portal refuses "multiple attachments"
College admission dashboards, HR portals, and visa checklists often want degree + marksheet + ID in a single upload field. Students email me screenshots of errors like "only one file allowed" while holding four separate PDFs. This merger runs in the browser — pick files, drag order if needed, download one combined PDF.
Merging does not shrink size. A 1.5MB file plus a 1.2MB file becomes roughly 2.7MB. If the cap is 2MB, merge first, then compress to 2MB.
Page order matters
How reviewers expect bundles to look
| Application type | Suggested order |
|---|---|
| Job application | Cover letter → resume → certificates |
| College admission | Application form → marksheets → ID proof |
| KYC bundle | Match the numbered list on the bank screen exactly |
Starting from photos?
JPG pages need a PDF step first
Merger accepts PDFs, not raw gallery JPGs. Convert each photo with Image to PDF, compress heavy pages with 200KB compressor before conversion if scans are huge, then merge here.

Mistakes
Why merged files get bounced
- Blank page inserted between scans — delete in a PDF editor before merge.
- Upside-down phone photos — rotate in gallery first.
- Same page added twice — common when people re-export marksheets.
