How to Make Your CV and Certificates Into One PDF for Ajira Portal 2026 **Written by: Frank, GridPDF User | Last Tested: September 30, 2026 on Ajira.go.tz | For: Watanzania wanaomba kazi serikalini** Last week my cousin in Dodoma was crying. Ajira Portal kept saying **"Invalid File"** and **"File Size Too Large"** when she tried to upload her CV, Degree Certificate, and Birth Certificate. She had 6 separate photos from a stationery in Nane Nane. Ajira wants ONE PDF under 2MB. This is the exact method that got her application submitted in 3 minutes on her phone. I use this for 20+ people every month. Why Ajira Portal Rejects Your PDF? (The Real Reason) I checked Ajira.go.tz requirements today. They require: 1. **One PDF only** - Not 5 files 2. **Maximum 2MB** - Most stationery scans are 8-15MB 3. **Clear QR and Text** - If your transcript QR is blurry, system auto-rejects If you upload many files, you will see "Upload Failed" forever. What You Need to Prepare for Ajira Portal Before you merge, prepare these in this exact order - this is the order PSRS wants: 1. Application Letter (Barua ya Maombi) 2. CV / Resume 3. Academic Certificates (Degree, Diploma) 4. Birth Certificate 5. NIDA Copy **Important:** Do not merge original photos. First convert each photo to clear PDF. Step-by-Step on Your Phone (No Laptop) **Step 1: Convert Your Photos to PDF** If you have photos of certificates, go to [GridPDF JPG to PDF Tool](gridpdf.com/image-tools/jpg-to-pdf). Upload all photos, it will make them clear PDF without watermark. I tested - other tools add "iLovePDF" watermark and Ajira rejects watermarked CVs. **Step 2: Arrange and Merge Into One PDF** Go to [GridPDF Merge PDF Tool] GridPDF.com/merge-pdf). Upload in this order: Application Letter > CV > Certificates > Birth Cert > NIDA. Click "Merge". Our tool will auto-compress to 1.5MB to pass Ajira 2MB limit. **Step 3: Check Before Uploading to Ajira** Open your final PDF and check: - Is your name on CV readable? - Is your Degree QR code scannable? - Is file size below 2MB? (You can check on our site after merge) My cousin's final file: From 14.7MB (6 photos) to 1.84MB (1 PDF) - Ajira accepted immediately. 3 Mistakes That Make Ajira Portal Say "Invalid File" **1. Merging Screenshots:** Don't screenshot your NIDA. Use real PDF. Screenshots become blurry. **2. Using CamScanner Free:** It adds watermark. Ajira system detects watermark as fraud. **3. Wrong Order:** If you put NIDA first and CV last, the officer may not see your CV. Always Application Letter first. FAQ - Maswali Yanayoulizwa Sana Ajira Portal **Q: Ajira Portal inasema "File too large" hata baada ya ku-merge?** Use our [Compress PDF Tool](gridpdf.com/compress) after merging. Set to "Under 2MB for Ajira". It will reduce from 5MB to 1.8MB without losing certificate clarity. **Q: Nawezaje kuunganisha Cheti cha Kuzaliwa na NIDA kwenye PDF moja?** Tumia Merge tool. Weka Birth Certificate page 1, NIDA page 2. Watu wengi wanapata shida kwa sababu wanatuma picha mbili tofauti. Ajira inataka moja. **Q: Je, ni salama kuweka vyeti vyangu mtandaoni?** Ndiyo, kama unatumia tool ya hapa nyumbani. GridPDF haifadhi vyeti vyako. Files zinafutwa baada ya saa 1. Sisi tuko Tanzania, hatutumi server za nje kama tools za India. Vyeti vyako havitauzwa. **Q: Ajira Portal login inagoma baada ya upload?** Hakikisha PDF yako sio scanned upside down. Mfumo wa Ajira wa 2026 unasoma QR, ukiwa upside down inagoma. Final Advice From Someone Who Helps People Daily Usikimbilie stationery saa 2 usiku kabla ya deadline ya Ajira.
