About This Tool
Photo Timestamp and GPS Stamper embeds permanent chronological and geospatial verification details directly into the pixel data of inspection and fieldwork photographs. It is built for construction supervisors, insurance adjusters, field technicians, and compliance auditors who must document site conditions with visible, tamper-evident date, time, and location credentials.
### Watermark Placement and Typography The tool renders your photo onto an HTML5 canvas at its native resolution, preventing blurriness or downsampling. It calculates text sizing dynamically to ensure legibility on both low-resolution mobile snapshots and high-resolution camera files: - **Proportional Font Size:** Computed as Math.max(16, Math.round(canvas.width * 0.022)) using bold monospace lettering. - **High-Contrast Styling:** Each text line is rendered with a 20% black stroke boundary (strokeText) overlaid with safety industrial yellow (#FFE600 fillText). This dual-tone styling remains readable over bright sky, dark asphalt, or patterned foliage. - **Three-Line Stack:** - TAG: Project code, claim number, or inspection label (bottom line). - GPS: Latitude and longitude coordinates (middle line). - DATE: Full calendar date and timestamp string (top line).
### Worked Example: Commercial Job-Site Inspection Stamp Suppose a field supervisor needs to certify structural rebar placement using a 4000 × 3000 pixel job-site photo: 1. **Load Source File:** Select site-rebar-east-wall.jpg (4000 × 3000 px). 2. **Configure Parameters:** - Date & Time: 2026-11-01 14:45:00 - GPS Location: 34.0522° N, 118.2437° W (Los Angeles, CA) - Claim / Tag: PROJECT #9042 / REBAR INSPECTION 3. **Typography and Position Calculations:** - Canvas dimensions: 4000 px wide by 3000 px high. - Dynamic font size: 4000 × 0.022 = 88 px bold monospace. - Outline border width: 88 × 0.2 = 17.6 px black stroke. - Vertical line separation: 88 × 1.35 = 118.8 px. - Line coordinates: - Tag line (bottom): X = 24 px, Y = 2976 px (3000 - 24). - GPS line (middle): X = 24 px, Y = 2857.2 px (2976 - 118.8). - Date line (top): X = 24 px, Y = 2738.4 px (2857.2 - 118.8). 4. **Save Output:** The canvas exports a 4000 × 3000 pixel JPEG at 92% quality rating with burned-in proof stamps in 110 ms.
### In-Browser Processing Details All watermarking operations execute locally within your web browser using HTML5 Canvas 2D methods. Photos selected from your filesystem are read into memory using FileReader data URLs and exported directly to your download folder. No photographic assets or location strings are transmitted to remote servers.

- 2
Enter or edit the Date & Time string to reflect when the photo was captured.
- 3
Input the GPS decimal or degrees latitude and longitude coordinates.
- 4
Enter the project identifier, inspection tag, or insurance claim reference.
- 5
Verify text readability in the preview display and click Download Stamped Photo to save your JPEG.
Frequently Asked Questions
Does this tool resize or compress my original photo dimensions?
No. The canvas matches your input image natural width and natural height pixel-for-pixel before stamping text lines.
Why are the text lines rendered in yellow with a black border?
Safety industrial yellow (#FFE600) with a heavy black outline ensures the stamp remains easily readable against dark shadows and bright reflective backgrounds.
Are my inspection photos uploaded to an external server?
No. The image is loaded into your local browser memory via FileReader and stamped entirely on your device canvas.
What format does the stamped image export in?
The finished stamped image is exported as a standard JPEG file at 92% compression quality.
