Merge PDF files and photos under an exact KB limit (100, 200, 500 KB)
Combine semester marksheets, Aadhaar front and back scans, or multiple certificates into a single ordered PDF—and automatically compress the merged file under the exact KB limit your portal demands.

Why Government Form Applicants Need a Size-Aware PDF Merger
Almost every Indian recruitment, scholarship, and counselling portal gives you one upload slot per document category—and pairs it with a strict byte ceiling:
- UPSC Civil Services & NDA (
upsconline.nic.in): Supporting certificates (caste, EWS, PwBD, degree/marksheets) must be uploaded as a single PDF between 50 KB and 300 KB. - National Scholarship Portal (
scholarships.gov.in): Every mandatory attachment is capped at 200 KB. - IBPS, SBI & Banking Document Upload: Multi-page certificates and experience proofs must be combined into one A4 PDF under 500 KB.
- GST Registration (
gst.gov.in): Proof of principal place of business (electricity bill + rent agreement) or multi-page appointment letters must be merged under 100 KB to 1 MB.
If you have four separate semester marksheets or the front and back of an identity card stored as separate PDFs and photos, a normal PDF merger just concatenates their bytes—leaving you with a 2.5 MB file that the portal immediately rejects.
Merge + Compress in a Single Client-Side Pass
This tool eliminates the two-step shuffle between a merger and a compressor:
- Mixed Input Queue (PDF + JPG/PNG): You do not have to convert phone photos to PDF before merging. Drop
.pdffiles alongside.jpgor.pngimages in one go, and reorder them with the up/down arrows. - Lossless Vector Copy When Under Budget: If you merge two lightweight text PDFs and their combined weight already sits below your KB target, the tool copies the original vector pages directly so text remains selectable and zero quality is lost.
- Automatic Multi-Page Budget Allocation: When the combined pages exceed your target KB (for example, 4 scanned marksheets totalling 3.2 MB that must fit under 300 KB), the engine renders the pages at print resolution and runs a binary search over JPEG encoding until the entire multi-page PDF lands just underneath your ceiling.
Practical Tips for Multi-Page Certificate Uploads
- Put the summary or final-year page first: Scrutiny officers often preview only Page 1 on their dashboard before opening the full PDF. Place your consolidated degree or final marksheet on Page 1, followed by earlier semesters.
- Crop dark table edges before merging photos: If one of your inputs is a phone photo of a certificate sitting on a dark wooden table, trim the table away first so the shared kilobyte budget is spent on the text.
How it works
- Drop two or more PDF files and/or JPG/PNG images into the box above (all files stay on your device).
- Use the ↑ and ↓ buttons beside each row to arrange the exact page sequence (for example, Aadhaar front first and address side second).
- Type your portal's maximum file size in the PDF size box (such as 200 KB, 300 KB or 500 KB) or tap a quick-size pill.
- Choose 'Standard' quality for multi-page text certificates or 'Print' quality when merging ID cards with QR codes.
- Click 'Merge files into one PDF' and download your combined, size-verified PDF document.
Common questions
merge pdf under 200 kb — can I combine two PDFs and compress them at the same time?
Yes. Standard PDF mergers simply stitch files together, so two 180 KB certificates become a 360 KB file that fails a 200 KB portal rule. Our tool merges the pages first and then runs a multi-page quality binary search so the combined PDF lands safely below your 200 KB, 300 KB or 500 KB ceiling.
Can I merge one PDF file and one JPG photo into a single PDF?
Yes. You can mix `.pdf` documents and `.jpg`/`.png` camera photos in the same queue. Any image is automatically placed onto a clean A4 page and combined with your PDF pages in the exact order you set.
How do I combine Aadhaar card front and back into one PDF under 100 KB or 200 KB?
Select both the front image/PDF and the back image/PDF, verify that the front side is item #1 in the list, type 100 or 200 in the KB box, and press Merge. The resulting two-page PDF will sit comfortably under your limit.
How many semester marksheets can fit inside a 500 KB merged PDF?
At 150–200 DPI, four to six A4 semester marksheets fit comfortably inside a 500 KB PDF with every subject code and grade clearly legible. For eight or more pages, choose 'Smaller file' in the quality dropdown.
Are my marksheets or identity documents uploaded to any server?
Never. Both the PDF assembly (via self-hosted pdf-lib) and page rendering (via pdf.js) run 100% inside your web browser. Your documents never leave your phone or computer.
