OGP Image Generator | Create Social Media Images in Your Browser

What this OGP image generator can do

Create social-sharing images at 1200 × 630, X post, 16:9, square, or custom dimensions. Add a title, subtitle, label, brand, logo, solid color, gradient, or background image without uploading your assets.

Steps to Create an OGP Image

1. Choose an Image Size That Fits Your UseFor web article sharing images, start with 1200×630. Use the presets for post-specific images or square assets.
2. Enter a Heading to Convey in the ImageDon’t cram the full article title; condense it to a length that makes sense even in a scaled-down view.
3. Set Background and TextChoose a color scheme or background image, and check the contrast between the heading and background in the preview.
4. Check the Safe Zone and Scaled-Down ViewKeep headings, logos, and faces inside so important information remains even if edges are cropped.
5. Choose FormatChoose PNG for text and graphics, JPEG for photos when you need smaller file size, or WebP if your target environment supports it.
6. Set the public URL in the meta tagEnter the absolute URL after uploading the image to your site, and place the generated tag in the head section.

Recommended OGP Image Sizes and Uses

Social network specs, display frames, and cropping methods can change. Even the same image may appear differently in timelines, profiles, messages, and search results. Don’t place important text or logos at the edges, and check the actual shared view after publishing.

Practical guidelines for readable headings

Keep the main message concise and check the preview at a small display size. The tool fits text by grapheme and avoids leaving common punctuation at awkward line starts.

Brand names, URLs, and long unbroken strings may still overflow. Shorten the text or reduce the maximum font size when the fit warning appears.

Background image cropping and focal point

The background image is displayed to fill the output frame, so parts with different aspect ratios are cropped. Use “horizontal focal point” and “vertical focal point” to move the crop area based on where you want to keep, such as a person’s face, product, or building. The left-right split layout places the photo on the right and reserves heading area on the left.

When overlaying white text on a photo, increase the “darkness of the veil.” The veil is the percentage of the image covered in black, which keeps the photo’s impression while making text easier to read. We also show the minimum contrast measured at multiple points in the drawn text area, but don’t rely solely on the number—visually check the area behind the text.

How to Use the Trim Safe Zone

The safe area is a guideline in case the social network or theme crops the image edges. Enabling this check shows a frame inside the preview. This frame is not drawn on the saved image. Place elements like headings, dates, and logos—whose meaning would change if cropped—inside the frame.

Even inside the safe area, there is no guarantee of full display on all services. Some services use circular thumbnails, tall cards, or their own center crops. If you use the same image for important ads or announcements across multiple platforms, it’s safer to create separate images at each platform’s dimensions.

Contrast Between Text and Background Colors

Contrast is measured after drawing solid colors, gradients, decorations, and background photos onto the canvas, sampling multiple points in the heading area, and showing the minimum ratio against the text color. A common guideline is 4.5:1 or higher for normal-sized text and 3:1 or higher for large bold text. Since photos vary in brightness by location, check both the number and the preview.

If contrast is insufficient, you can change the text to white or a dark color, darken the background, strengthen the overlay, or place a solid area behind the text. Just adding a strong shadow or outline to text can cause the outline to collapse at small sizes. Prioritize readability through color and area contrast.

How to choose PNG, JPEG, or WebP

JPEG has no transparency, so this tool composites onto a white background before saving. After saving, open the file and check for missing text, blurry images, color, and file size. Even at high quality, a small original background image will become rough when enlarged.

Notes when setting OGP meta tags

Set og:image to the absolute URL of a published image that viewers’ browsers can fetch. Local file names or URLs visible only in the admin panel won’t work. Set og:image:width and og:image:height to the actual image dimensions, and in og:image:alt, briefly describe what the image shows, not just mechanically repeat the text in it.

This tool generates og:type, og:title, og:description, og:url, og:image, image dimensions, alternative text, and summary_large_image X card tags. If your CMS or SEO plugin already outputs the same tags, don’t duplicate them; register the image and text in its settings screen. After publishing, check the page HTML and each service’s card preview to confirm the reflection.

Processing without sending images, logos, or input

Background image and logo loading, canvas drawing, text measurement, auto line breaks, cropping, and PNG/JPEG/WebP conversion all happen in your browser. Selected images, headings, URLs, and meta tags are not sent to WiseChecker servers, external APIs, or image generation AI.

Reloading the page clears your input, loaded images, and results. Even internal images with confidential information can be processed without sending off-device, but you must check where you save the files, who you share them with, and your cloud sync settings. Also, background images, logos, and fonts have copyright and trademark terms.
