## Direct Answer Guides (Standard Operating Procedures)

### 1. How to Convert an Aadhaar PDF to a Printable PVC Card (CR80 Standard)
1. **Upload Document:** Visit [Aadhaar PDF to PVC Card](https://pixdok.com/aadhaar-pdf-to-pvc-card) and upload the official e-Aadhaar PDF. If password-protected, enter the 8-character password (first 4 letters of name in capital + 4-digit birth year).
2. **Automated Processing:** PixDok extracts the front and back card portions, removes excess margins, aligns the sections, and renders them at 300 DPI.
3. **Download & Print:** Download the print-ready PDF formatted to standard CR80 size (85.60 mm × 53.98 mm) on an A4 sheet ready for thermal or inkjet PVC printing.

### 2. How to Make a Compliant Passport or Visa Photo
1. **Upload Photo:** Go to [Passport Photo Maker](https://pixdok.com/passport-photo) or country-specific tools ([US Visa](https://pixdok.com/us-visa-photo-maker), [UK Passport](https://pixdok.com/uk-passport-photo-maker), [Schengen Visa](https://pixdok.com/schengen-visa-photo-maker)).
2. **Crop & Background:** Align face within official biometric guide lines. Optionally isolate and replace the background with plain white or light grey.
3. **Generate Print Sheet:** Select single photo download or a multi-photo print sheet (4×6 inch or A4 layout) at 300 DPI.

### 3. How to Compress Large PDF Documents
1. **Select Document:** Open [Compress PDF](https://pixdok.com/compress-pdf) and drag in any PDF up to 100 MB.
2. **Choose Compression Level:**
   - *Recommended Compression:* Ideal balance between significant size reduction and crisp visual quality.
   - *Extreme Compression:* Maximum reduction for strict government/job portal upload ceilings (e.g. under 200 KB or 500 KB).
   - *Less Compression:* High-fidelity reduction for image-heavy portfolios and certificates.
3. **Download:** Instantly download the reduced PDF without watermarks or metadata bloat.

### 4. How CSC Centers & Cyber Cafes Print 5 PVC Cards on One A4 Sheet (Batch Workflow)
1. **Prepare Standard CR80 Card Layouts:** Upload official e-Aadhaar, PAN, Voter ID (e-EPIC), Ayushman Bharat (PM-JAY), or ABHA Health ID PDFs to PixDok's respective card tools. PixDok automatically extracts, crops, removes margins, and formats both front and back into standard ISO/IEC 7810 CR80 dimensions (85.60 mm × 53.98 mm / 1011 × 638 pixels at 300 DPI).
2. **Select Multi-Card A4 Print Layout:** Select the "A4 Multi-Card Sheet" output. PixDok positions 5 cards (paired front and back side-by-side, totaling 10 card faces) with 2 mm cutting guides and uniform margins calibrated for standard inkjet photo trays and desktop laminating.
3. **Printer Hardware Setup:**
   - **Paper Type:** Premium High-Glossy Photo Paper (180 to 250 GSM) or Inkjet PVC Core Printable Sheets.
   - **Printer Settings:** Select "Photo Paper Glossy", Quality set to "High / Best", and strictly enforce **100% Scale** (turn OFF "Fit to Page" or "Shrink to Printable Area" to prevent dimension distortion).
4. **Lamination & Die-Cutting:**
   - Laminate the printed sheet using thermal laminating film pouches (250 micron / 10 mil recommended for standard ATM-like card rigidity).
   - Cut each individual card using a heavy-duty manual desktop PVC card cutter / punch (85.60 × 53.98 mm with 3.18 mm rounded corner radius).
   - Result: 5 durable, water-resistant, pocket-sized cards from a single A4 sheet with zero paper wastage.
