How Local Processing Works

1

Selected in Browser Memory

When you select or drop a file, your browser creates a temporary local Blob / ArrayBuffer pointer directly in your device's RAM.

2

Processed Client-Side

Our client-side engine (HTML5 Canvas & Client JavaScript) processes the data directly using your computer or phone's CPU.

3

Saved Directly to Your Downloads

The resulting output is downloaded immediately to your device. When you close or refresh the tab, memory is cleared automatically.

Verify It Yourself

Open your browser's Developer Tools (F12 or Ctrl+Shift+I), switch to the Network tab, and convert any file. You will see zero network POST requests carrying file data.

Optimizing Images for Social Media Platforms

Every major social media platform (Instagram, YouTube, LinkedIn, X/Twitter, WhatsApp) enforces specific aspect ratio and pixel dimension standards. Uploading images with incorrect dimensions leads to automatic compression artifacts, awkward cropping, or blurred banner headers.

Understanding Fitting Modes

  • Cover Mode: Scales the image to fill 100% of the target canvas area while maintaining aspect ratio, centering the graphic and cropping excess edges.
  • Contain Mode: Scales the image so the entire graphic is visible within the frame, padding remaining letterbox areas with your selected background color.
  • Stretch Mode: Forces the image to conform to the exact target dimensions regardless of original aspect ratio.

Client-Side Canvas Rendering & Privacy

All image resizing and canvas operations are executed in real time inside your browser tab using the HTML5 2D Canvas API. Your files are processed on your device and are never uploaded.

Frequently Asked Questions

What social media aspect ratio presets are included?

Our tool includes exact dimension presets for Instagram Square (1080x1080), Instagram Portrait (1080x1350), Instagram Story/Reels (1080x1920), YouTube Thumbnail (1280x720), LinkedIn Banner (1584x396), and WhatsApp Profile DP (500x500).

What is the difference between Cover, Contain, and Stretch fit modes?

Cover fills the entire preset dimension by scaling and center-cropping the image without distortion. Contain scales the image to fit entirely within the bounds, filling empty space with a solid background color. Stretch stretches the image to fit the exact dimensions.

Are my social graphics uploaded to any server?

No. All scaling, cropping, and canvas rendering happen 100% locally inside your web browser memory. Your files are processed on your device and are never uploaded.

What output image formats are supported?

You can export your resized social graphics as WebP (optimized for web speed), JPEG (maximum compatibility), or PNG (crisp text and vector graphics).
