Photo + Signature
Photo & Signature Joiner
Combine your photograph and signature into a single image for exam and government form uploads — with an exact pixel size and KB limit if the portal demands one. Both images are combined in your browser and never leave your device.

Private by design: Both images are decoded and combined inside your browser using the HTML canvas. Neither file is uploaded to any server, so this is safe for ID photographs and signatures.
Join Photo and Signature in One Image Online Free
Photo and Signature Joiner is a free in-browser utility that combines your passport photograph and signature into a single composite image without uploading either file to a server. Many competitive examination portals, university registration systems, and recruitment forms require a unified image file conforming to strict pixel dimensions and a maximum KB file size. Upload both files, choose a vertical stacked or horizontal side-by-side layout, lock your required canvas dimensions, and let the client-side binary search encoder hit your exact KB budget.
How to Join a Photo and Signature in 4 Steps
Add Photograph
Browse or drag your passport photo into the photo input box.
Add Signature
Upload a clean scan or cropped phone photo of your signature.
Configure Limits
Choose layout, lock exact pixel dimensions, and set a target KB limit.
Download Result
Inspect the rendered canvas and download the composite JPEG or PNG.
Government & Recruitment Exam Upload Specifications
Candidate application portals enforce strict validation gates. Submitting incorrect pixel dimensions or exceeding byte limits leads to instant form rejection. Refer to official portal guidelines:
| Examination Portal | Required Layout | Pixel Dimensions | File Size Ceiling | Format |
|---|---|---|---|---|
| Staff Selection Commission (SSC CGL / CHSL) | Stacked (Photo above Sign) | 400 x 500 px (3.5 x 4.5 cm) | 20 KB to 50 KB | JPEG |
| IBPS Bank PO / Clerk / RRB | Stacked or Separate | 200 x 230 px (Photo), 140 x 60 px (Sign) | 20 KB to 50 KB | JPEG |
| UPSC Civil Services / NDA / CDS | Unified / Dual Panel | 350 x 350 min to 1000 x 1000 max px | 20 KB to 300 KB | JPEG |
| State PSCs (UPPSC, BPSC, MPPSC, TNPSC) | Stacked (Composite Card) | 350 x 500 px or 600 x 700 px | Under 50 KB | JPEG |
| Railway Recruitment Boards (RRB NTPC) | Stacked with White Margin | 320 x 400 px | 30 KB to 70 KB | JPEG |
Technical Pipeline: Aspect Ratio and KB Enforcement
Passport photos typically have a 3:4 aspect ratio, while signatures are wide and narrow (often 3:1 or 4:1). The tool computes scale multipliers separately for each image and centers them within allocated canvas sub-regions. Your facial proportions and handwriting curves are never stretched or distorted.
When you enforce both an exact pixel dimension (such as 600 x 700 px) and a maximum file size (such as 50 KB), the tool retains the exact pixel matrix while executing a binary search over JPEG DCT quantization tables to ensure the final payload satisfies portal upload validators.
Rendering source photos onto an HTML5 canvas strips camera model data, device serials, and GPS location coordinates. If you need to verify or scrub individual metadata tags on raw scans before combining them, use our Image Metadata Remover.
Need to check text legibility on your scanned admit card or extract registration numbers from a digital receipt? Use Image to Text (OCR) or scan verification codes directly using our QR Code Scanner.
Why Use TryDocsy to Combine Photo & Signature?
100% Client-Side Privacy
Your biometric photograph and signature never leave your device. All rendering executes in browser memory.
Exact Dimension Locking
Set exact width and height in pixels as mandated by competitive examination guidelines.
Strict File Size Budget
Compresses to 20 KB, 50 KB, or 100 KB thresholds using iterative binary search quality matching.
Stacked or Side by Side
Position signature beneath the photo or side by side with customizable canvas margin spacing.
Zero Distortion Centering
Both images maintain original aspect ratios without stretching, squashing, or skewed proportions.
Free Without Registration
No accounts, no payment paywalls, no email collection, and no watermark stamps on final images.
Frequently Asked Questions
Are my photo and signature uploaded to an external server?
No. Both images are loaded and combined directly inside your browser using the HTML5 canvas element. Neither file leaves your device. There is no account registration, no remote queue, and no temporary cloud storage. This local model keeps passport photographs, ID cards, and official signatures secure.
Which exam and recruitment portals require a combined photo and signature?
Several government recruitment boards (including select SSC, IBPS, RRB, state PSC, and university admissions portals) require a single composite image file rather than separate uploads. Always verify the official notification: if the portal has two separate file upload buttons, submit them individually instead.
How does the tool enforce a strict KB limit such as 20 KB or 50 KB?
Enable the target file size option and specify your required ceiling (for instance, 50 KB). The engine uses binary search JPEG quantization to find the optimal quality factor that satisfies your byte budget. If you also lock exact pixel dimensions, the canvas width and height remain fixed while only compression quality is adjusted.
Which source image formats can I upload?
You can upload JPG, JPEG, PNG, WebP, and BMP images for both the photo and signature inputs. The final merged output downloads as JPG or PNG. When a target KB cap is specified, the tool automatically selects JPEG because PNG uses lossless compression that cannot be scaled to arbitrary file size targets.
What canvas dimensions should I choose if the portal notification is unspecific?
A canvas size of 600 x 700 pixels with a 50 KB cap is standard for stacked layouts. It provides sufficient clarity for identity verification while remaining compatible with restrictive upload filters. If your portal states exact pixel requirements, enter those numbers directly into the dimension fields.
Will my signature look distorted if it is wider than the photograph?
No. The joining algorithm calculates scaling independently for each image to preserve original aspect ratios. Both the photo and signature are centered within their canvas slots without stretching or squashing. You can also adjust the vertical gap slider and background color to match portal requirements.
Can I remove camera metadata before joining my files?
Yes. By default, drawing images onto a browser canvas discards all source EXIF, GPS coordinates, and camera device serial numbers, ensuring the downloaded composite image contains zero personal location tracking metadata.
