You share a link, and the platform shows… nothing. No preview card, a cropped thumbnail, or a headline cut off mid-word. The image that decides whether anyone clicks is the Open Graph image: a 1200×630 card that Facebook, X, LinkedIn, and WhatsApp all read from your page's meta tags. Making one by hand means opening a design tool, setting up the exact canvas, and exporting at the right size.
Pixora's OG Image Generator promises to do it in the browser, for free, with no sign-in: upload a background, type a headline, pick one of three layouts, and download a 1200×630 card plus the meta tags to paste into your page. Rather than take that at face value, we tested it with a purpose-built background and a deliberately long headline — and measured exactly what came out. The exports are genuinely correct. But two of the three layouts produce literally the same file, and a long headline silently breaks something in every layout.
What the tool offers
The tool's page describes three layouts — Ambient Glow, Editorial Split, and Minimalist Card — over an exact 1200×630 canvas, with a live preview, custom headline, category badge, domain, and a "Copy Meta" button for the tags. The page also advertises "Typography" and a "custom author badge," and states that JPG, PNG, and WebP backgrounds are supported. Processing, per the page, happens entirely in your browser with nothing uploaded; that is the tool's own claim, and we did not independently network-test it.
One thing to know before you start: there is no blank-card or template-only mode. The editor only opens after you upload a background image — the entry point is a drop zone reading "Drag background image here to create OG card." If you just want a text card with no photo behind it, this tool cannot start one.
How we tested it
We generated a synthetic 1920×1080 JPEG background (99,417 bytes) with a gradient and shapes, so any cropping, scaling, or blur would be measurable, and uploaded it through the tool's file picker. We then entered a 117-character test headline — "Hands-on test of the Pixora OG Image Generator: three layouts, 1200x630 PNG exports, and meta tags checked end to end" — plus a subtitle, category "TEST", and the default domain, and exported all three layouts. Every downloaded file was checked locally for format, pixel dimensions, byte size, and hash. The headline was deliberately long: real headlines run long, and silent truncation is the failure mode that matters most for a card whose whole job is to be read at a glance.
Test 1: The exports are exactly 1200×630 — but two layouts are the same file
All three downloads are PNG files measuring exactly 1200×630, as promised:
| Layout | Size | SHA-256 (first 16 chars) |
|---|---|---|
| Ambient Glow | 732,074 bytes | a636a408dfa4b4cf |
| Split Card | 225,020 bytes | 6e870ffd488fc3e8 |
| Minimalist Card | 732,074 bytes | a636a408dfa4b4cf |
Read the hashes, not just the sizes: Ambient Glow and Minimalist Card produced byte-identical files — the same SHA-256, the same 732,074 bytes. Not a similar look, the same output. For the inputs we used, picking between those two layouts changes nothing at all. Only Split Card is a genuinely different render, and it is much smaller (225,020 bytes), which fits a layout with large flat areas rather than a full-bleed blurred photo.
That may depend on the inputs — a different background or accent colour could separate them — but on a normal test, one of the three choices is a duplicate. If you are choosing between Ambient and Minimalist, stop deliberating: download either one.
Test 2: A long headline breaks something in every layout
The 117-character headline is where the layouts genuinely differ — and where each one fails in its own way:
- Ambient Glow: the full headline wraps onto three lines, fully visible — no truncation. But the subtitle disappears from the preview entirely. With a short headline the subtitle renders underneath; with a three-line headline it is crowded out. Nothing warns you; the subtitle is just gone.
- Minimalist Card: identical behaviour to Ambient — full three-line headline, no subtitle.
- Split Card: worse. Only about 62 of the 117 characters render ("Hands-on test of the Pixora OG Image / Generator: three layouts,") and the rest is cut off with no ellipsis and no further lines. The subtitle is absent here too.
So the practical rule is simple: keep your headline short enough to fit on two lines in Ambient/Minimalist, and shorter still — roughly 60 characters — in Split Card. And if the subtitle matters to you (it carries the description or author line), check the preview after typing the headline: a long headline deletes it silently in all three layouts.
Test 3: The editor — what is actually there, and what is missing
The editor is a single panel, and its real control list is shorter than the page copy suggests:
- Headline Title (free text; no character limit is shown), Subtitle (labelled "short description or author name"), Category, and Domain (default
pixora.dev), plus an accent colour (default#FF7A45) and the layout dropdown. - No separate author field, no logo upload, and no font controls anywhere — despite the header strip advertising "Typography" and the page copy promising a "custom author badge." Typography is fixed; if you need your logo on the card, it has to already be part of your background image.
Three behaviours worth knowing before you spend time on a card:
- Removing the background image resets the entire editor. Headline, subtitle, category, and layout all revert to defaults. Do not remove the image to "start over" unless you mean to lose everything.
- The category badge updates only after the field loses focus. While you are typing, the preview keeps showing the old category — click elsewhere before judging the result.
- The layout names do not match the documentation. The How-to steps and FAQ call the second layout "Editorial Split"; the actual dropdown calls it "Split Card." Same layout, two names — use the dropdown's name when following a guide.
Minor naming quirks elsewhere: the homepage lists the tool as "Social OpenGraph Card Studio," the tool page calls it an "OG Image Generator," and its breadcrumb reads "← Back to Image Compressor" although this is a standalone tool. Cosmetic, but the kind of thing that makes you double-check you are in the right place.
The meta tags
The "Copy Meta" button works: clicked twice with our test values, it confirmed "Meta Tags copied!" both times. One honest limitation of this test: our browser session could not read the clipboard back, so we cannot reproduce the tool's generated snippet verbatim here — and we will not quote the FAQ's placeholder example (yourdomain.com) as if it were the tool's output. What the tool's own FAQ does say, and what we recommend regardless of generator: paste the tags into your page's <head> and verify the result with Facebook's Sharing Debugger or X's Card Validator before you share the link. A card you have not previewed in the validator is a card you have not tested.
How to use it well
- Prepare your background first, at 1920×1080 or larger. The tool needs an image to start, and a wide, high-resolution source gives the blur and crop room to work.
- Write a headline under ~60 characters if you might use Split Card, and under two lines in the other layouts. Then check the preview: if your subtitle vanished, shorten the headline.
- Do not rely on the subtitle for essential information. It disappears whenever the headline runs long.
- Pick Ambient or Minimalist — not both. On our test they produced the same file, so choose one and move on; only Split Card is a different card.
- Put your logo in the background image if you need one on the card; there is no logo upload.
- Never remove the background mid-edit unless you want to start over — it resets everything.
- Validate before sharing. Paste the meta tags into your page, then run the URL through Facebook's Sharing Debugger (and X's Card Validator if you post there). The download being correct does not guarantee the platform reads it correctly.
Verdict
The core promise holds: a free, no-sign-in tool that turns a background image and a headline into a verified 1200×630 PNG, with three layouts to choose from. The headline finding is that there are really only two layouts — Ambient and Minimalist produced the identical file in our test — and the trap is the long headline: Split Card truncates it without warning, and every layout silently drops the subtitle when the headline runs to three lines. Keep the headline short, check the preview, validate the link, and it does the job in under a minute. Just do not expect typography controls, a logo upload, or an author field: those are advertised, not present.
Methodology and sources
All measurements are our own, run on 5 November 2026. Sample: a synthetic 1920×1080 JPEG background (99,417 bytes, SHA-256 prefix 9474b7a6510d8f48), generated with Pillow. Test values: 117-character headline, subtitle "Test subtitle: verifying the preview, the exports, and the meta output", category "TEST", domain "pixora.dev" (default), accent #FF7A45 (default). Exports verified locally with file inspection: format, pixel dimensions, byte size, and SHA-256 for each layout. The first export attempt in a background browser session was blocked by the browser itself (no file picker appeared); the successful test ran in a foreground session, where upload worked on the first attempt. The tool-generated meta snippet was not captured verbatim because the test browser could not read the clipboard; the article discloses this rather than quoting the FAQ placeholder. "Processes in your browser / never uploaded" is attributed to Pixora; not network-tested.
