The Invitation Card Maker is 100% client-side. Each element — a line of text, a decorative ornament, a shape or a photo reference — is a plain typed object held in the page, and a pure engine draws them onto an in-browser HTML5 <canvas>. When you upload a photo it is read straight into an in-memory Image via an object URL and drawn on-device, so it never leaves your computer and is never sent anywhere. Each side keeps its own background photo. The decorative ornaments are generated locally as vector paths — there is no stock imagery and no CDN. Export renders the same scene to a canvas at full print resolution and saves it with canvas.toBlob, and the 2-page PDF is assembled locally with pdf-lib from your own rendered pages, so every file is produced on your device. The only optional network use is loading an elegant display or script font you pick from Google Fonts, and consent-gated ads; system fonts and everything else work offline once the page is cached. Close the tab and the design is gone unless you exported it.

The most popular invitation size is 5×7 inches, also called A7 — it gives room for an elegant design, slips into a standard A7 envelope and almost always mails with a single stamp. Smaller options include 4×6 in (a postcard/photo size) and A6 (105×148 mm), and a square 5×5 in card reads as modern. The tool offers all four at their true trim size and 300 DPI, in portrait or landscape. For a professional print shop you should add the standard 3 mm / 0.125 in bleed yourself — turn on the print guides to see the bleed line and a safe-margin line, and keep the names and key details inside the safe area so nothing is trimmed off. For home printing you can print the exported image or PDF directly onto card stock.

Every element is its own layer you can drag, resize from eight handles, rotate, re-stack, duplicate and delete. Text layers cover the invitation fields (event title, host or couple’s names, date & time, venue/address and RSVP/details) with a choice of elegant fonts — offline system serifs plus optional Google display and script faces such as Great Vibes, Playfair Display, Cormorant Garamond and Dancing Script — and full control of size, weight, colour, alignment, line-height, letter-spacing and italics. The ornament library is drawn entirely in-browser as brand-neutral vectors (no stock art, no watermark): frames and corner brackets, botanical laurels, wreaths and sprigs, a leaf divider and a calligraphic flourish, interlocking wedding rings, a heart, a boho arch, confetti and a star — each recolourable and freely resizable. A segmented control switches between the front and the back (great for a map, registry, RSVP card or thank-you), and each side keeps its own background — solid, gradient, tiled pattern or your own photo.

You can export the visible side as a full-resolution PNG or JPEG (or a half-size copy for web/email), copy the image straight to your clipboard, or build a print-ready 2-page PDF that contains the front and the back at their true physical size, assembled locally with pdf-lib. The same render routine draws the preview and the export, so what you see is what you download. One honest caveat: exports are raster images in the screen’s RGB colour space, while commercial presses use CMYK ink with a smaller gamut, so bright, saturated colours can look slightly duller or shift in print — request a printed proof for colour-critical jobs and design a touch more conservatively. The presets are true trim sizes at 300 DPI, so add the 3 mm / 0.125 in bleed yourself (the guides show it) if a print shop requires it. Elegant display fonts load once from Google Fonts and, if you export before they finish, fall back to a system font — the tool waits for fonts to be ready first, but give a slow connection a moment.
