The Story Behind GreetingCardGo

When you want to send someone a heartfelt birthday wish, a thank-you note, or a holiday card, the common options often fall into two extremes:

Generic plain text messages on chat apps, which feel rushed and lack personal touch.
Complex graphic design software (like Photoshop or bloated multi-purpose design suites), where choosing fonts, layout spacing, and exports feels overwhelming for non-designers.

To bridge this gap, we built GreetingCardGo — a web-based, template-first digital greeting card generator designed to let anyone create polished, personal cards in under two minutes.

Image Compression & Privacy: Why You Shouldn't Upload Private Photos to Online Tools

Every day, millions of people drag photos into online compression tools without thinking about where those images actually go. The answer, for most popular tools, is: to someone else's server.

For generic photos this may be acceptable. For private images, it's a risk worth understanding.

Your image is uploaded via HTTPS to the tool's servers (or a third-party CDN)
The image is processed by their algorithm on their hardware
The compressed result is returned to your browser for download
The original and/or processed image is stored temporarily (duration varies by policy)
Depending on the tool, your image data may be logged, analyzed, or used for model training

Most reputable tools delete files within 1–24 hours. But "temporarily stored" still means your image existed on their infrastructure — subject to their security practices, their data residency, and their privacy policy.

Which Images Should You Never Upload?

🛂 Passport & ID photos — Biometric data. Use a local tool.
🏥 Medical images — May be subject to HIPAA or GDPR
🏢 Unreleased product designs — Proprietary IP
📋 Signed contracts & legal documents — Confidential PII
💳 Financial statements — Account numbers, balances
👤 Photos of children — Parental responsibility
🔐 NDA-covered client work — You may be contractually prohibited

Tool-by-Tool Privacy Comparison

Tool	Processing	Uploaded?	Safe for Private Photos
TinyPNG	Server-side	✅ Yes	⚠️ Use with caution
Compressor.io	Server-side	✅ Yes	⚠️ Use with caution
iLoveIMG	Server-side	✅ Yes	⚠️ Use with caution
Squoosh	Browser (WASM)	❌ Never	✅ Safe
ImgMin	Browser (Canvas API)	❌ Never	✅ Safe

How to Verify a Tool Processes Locally (30 seconds)

You don't have to take anyone's word for it:

Open the image compression tool in your browser
Open DevTools (F12 / Cmd+Option+I on Mac)
Click the Network tab and clear the log
Drop an image to compress
Watch the Network tab — if your image is sent anywhere, you'll see it here

For browser-only tools like Squoosh or ImgMin, you'll see zero upload requests. Your image never leaves your browser.
