Tips for Better Social Media Images

Make every pixel count with these creator-tested best practices.

Always Use the Exact Dimensions

Platform algorithms may crop or compress images that don't match recommended sizes. Exact dimensions ensure your image displays as intended on all devices.

Colour-Match Your Brand

Use the Custom background fill to match your brand colours. Consistent colour usage across posts builds instant visual recognition in crowded feeds.

Use Blur Fill for Portraits

When resizing a portrait photo for a landscape preset (like YouTube Thumbnail), use Blur background to fill the side bars with a stylish, matching background.

Export JPG for Social, PNG for Print

JPG at 90% quality is the ideal format for social media uploads — small file size, fast upload. Use PNG for designs with transparency or text-heavy graphics.

Keep Key Elements in the Safe Zone

Some platforms (Instagram, Facebook) overlay UI elements near the edges of cover photos. Keep faces, logos, and text away from the outer 10% of the frame.

Test Before You Post

Download your image, open it on your phone, and check that text is readable and faces are centred before uploading to the platform.

About This Tool

Canvas-Based Rendering

All image processing uses the browser's native HTML Canvas API. There is no image uploaded to any server. Your files are read locally via FileReader and rendered at the exact platform resolution.

Drag to Reposition

After uploading, drag directly on the preview canvas to reposition your image within the frame. Use the Zoom slider to scale, and Fit / Fill buttons for quick framing.

Full-Resolution Export

The preview on screen is scaled down to fit your display, but the download is always at the full preset resolution. A 1080×1080 Instagram Post will be downloaded as a 1080×1080 pixel image.

100% Private

Your images never leave your device. No accounts, no cloud storage, no analytics on your content. The tool works offline once the page is loaded.

Frequently asked questions

Quick answers about this free online tool.

No. Everything runs entirely in your browser using the HTML Canvas API. Your images are never sent to any server, logged, or stored anywhere. They exist only in your current browser tab and are gone the moment you close it.

You can upload PNG, JPG/JPEG, WebP, and GIF files. The browser's FileReader API handles loading, so any format your browser supports can be used. Note: animated GIF frames are not supported — only the first frame will be used.

Blur fills the canvas with a blurred, scaled version of your uploaded image. This is perfect for portrait-oriented photos placed in landscape presets (like YouTube Thumbnails) — instead of white bars on the sides, you get a stylish blurred background matching your image colours.

JPEG and WebP exports use lossy compression. The Quality slider controls the compression level — 90% is recommended for social media (small file, high visual quality). PNG export is always lossless and produces the highest quality but larger files.

Yes. The canvas is always rendered at the full preset resolution (e.g., 1080×1080 for Instagram Post). The smaller preview you see on screen is just a CSS-scaled display. The downloaded file will always be at the exact platform dimensions.

Fit (zoom = 100%) scales your image so the entire image is visible within the canvas — you may see background colour on the sides or top/bottom. Fill scales the image to completely cover the canvas — the image may be cropped on the edges. Drag to reposition after filling.

Switch between platform presets using the preset grid on the left. Each time you switch, the zoom and position reset so you can reframe the image for that platform's dimensions. Download each one separately.
