Merge ID Card Front and Back — For Printing or Online Verification, Free & Private
Merging the front and back of an identification document into a unified, high-resolution file is a frequent requirement for banking KYC portals, job onboarding verification, visa applications, and physical photocopy reproduction. When printed or uploaded haphazardly, misaligned or oversized ID documents are frequently rejected by automated identity verification scanners. This in-browser tool merges driver's licenses, national ID cards, PAN cards, resident permits, and passport cards cleanly at true 300 DPI resolution.
1. Printing at Photocopy Shops & Home Printers
When printing ID cards on standard A4 paper, photocopy shops often struggle with scale distortions. By entering your card's dimensions (defaulting to standard 85.6mm × 54mm or any custom size) and choosing A4 Print Output Mode, your card prints at 100% exact 1:1 real-world physical scale at 300 DPI. You can choose vertical stacking or side-by-side arrangement, leaving ample margin for lamination or folder filing.
2. Online KYC Portals & Verification Uploads
Most institutional KYC verification portals only provide a single file upload input field. Uploading only the front side results in immediate application rejection. Our Compact Output Mode crops tightly around both sides of your card with an optimal 5% border, maintaining barcode and text legibility while keeping file sizes under 2 MB upload limits.
100% Client-Side Privacy Guarantee
Identity documents contain sensitive personal identifiable information (PII) including social security numbers, full names, dates of birth, and biometric photos. Unlike commercial file conversion websites that upload your documents to cloud servers, this tool executes 100% in your local web browser using client-side HTML5 Canvas and WebAssembly. Your images are never transmitted over the internet or saved on any remote database.
Frequently Asked Questions (FAQ)
What card sizes and dimensions can I merge with this tool?
You can merge identification documents of any size worldwide. The tool defaults to the ISO/IEC 7810 ID-1 standard (CR80 format: 85.60 × 53.98 mm / 1011 × 638 px @ 300 DPI) common to driver's licenses, national IDs, and credit cards, but you can enter custom width, height, and corner radius in millimeters, inches, or pixels for passport booklets, badges, voter cards, or employee credentials.
Why do KYC verification portals require both front and back on one page?
Identity verification APIs and automated OCR scanners often enforce a single document upload rule per verification step. The front contains your facial portrait and primary details, while the back contains optical machine-readable zones (MRZ), barcodes, or residential address data. Merging both onto one page satisfies automated validation checklists in a single pass.
How should I print this file at a local photocopy or print shop?
Choose the A4 Print Output Mode and export as a PDF Document. When opening the file in Adobe Acrobat or sending it to the photocopy machine, ensure the print scale is set to "Actual Size" or "100%" (do not select "Fit to Printable Area"). This ensures your printed card matches real physical dimensions down to the millimeter.
Is my uploaded ID card data safe and confidential?
Yes, completely. All image rendering, scaling, card alignment, and PDF/PNG generation runs entirely inside your device's memory via native browser APIs. Your files are processed locally in your browser and are never uploaded or transmitted to any remote server.
