I’m a remote IT professional who recently relocated from Texas to Hawaii. My family has a background in the legal field, and even in 2026, we still deal with a surprisingly high volume of physical mail.
I got fed up with fighting Microsoft Word's margin settings just to print a single envelope. Most online tools either look like they're from 1998 or require you to upload your sensitive address list to their servers. So I built toEnvelope.com to solve my own frustration.
CORE FEATURES
1. WYSIWYG Editing: You edit directly on the virtual envelope. No "fill-form-and-preview" cycle. What you see is exactly what hits the paper.
2. Physical Hardware Tips: I’ve ruined enough envelopes to know that software is only half the battle. I added a 'Preview Mode' with specific tips (like using the manual tray or rear output) to prevent envelopes from curling.
3. Broad Size Support: From the standard #10 to business reply (#9) and invitation sizes (A2, A6, A7).
4. The Feedback Loop: I’ve included an anonymous tool to collect printer model data. Since every printer has its own alignment quirks, I’m hoping to crowdsource a compatibility matrix for offset adjustments.
PRIVACY AND DATA HANDLING
1. Local Processing: The PDF generation and address rendering are 100% client-side. Your addresses never touch my server.
2. Minimal Telemetry: I use Cloudflare Functions to collect basic, anonymous usage events (like "envelope printed") so I can see which sizes are actually being used. No third-party ad trackers.
3. Opt-in Feedback: If you choose to leave your email for a follow-up in the feedback tool, that data is sent to a private CF Function only with your explicit consent.
A QUICK STORY ABOUT MY "FIRST CLIENT"
My family members were my first users, and they had a very specific requirement: sending legal docs to Canada using DL envelopes which required specific logic. I spent a good chunk of time building a conditional trigger for that niche case, even though we rarely use DL for domestic US mail. It was a good reminder that satisfying the needs of your "first client" is often the most important part of the journey.
There are no signups or paywalls. I’m curious to hear about any weird printer quirks you’ve encountered or if there are other common sizes I should add.
