📐 How Does Canvas Padding & Scaling Work?

1. Scale Factor: Scale = Min((TargetW × (1 - 2 × Pad%)) ÷ ImgW, (TargetH × (1 - 2 × Pad%)) ÷ ImgH)

2. Centering Offsets: X = (TargetW - (ImgW × Scale)) ÷ 2, Y = (TargetH - (ImgH × Scale)) ÷ 2

3. Zero-Crop Guarantee: Scales down the longest dimension to fit inside the inner padded safe zone while filling the outer border with your selected solid or edge-sampled background.

How to make non-square supplier photos square without cutting off product?

Standard image croppers chop off top/bottom product edges. Our normalizer uses non-destructive canvas letterboxing: it centers your rectangular photo inside a 2048×2048 square container and pads the remaining space with matching white, cream, or auto-sampled background color.

How to batch add white border padding to product images for Shopify grid?

Drag and drop up to 100 product images. The client-side HTML5 canvas engine automatically applies 2048×2048 square padding, standardizes alignment across your entire catalog, and exports an instant ZIP archive in high-quality WebP format.

Why is 2048x2048 WebP the recommended standard for Shopify in 2026?

Shopify recommends 2048×2048 pixels for sharp zoom functionality on high-DPI desktop and mobile retina screens. WebP compression provides 30% smaller file sizes than JPEG/PNG, boosting Google Core Web Vitals and page load speed.

Can I auto-sample background color from supplier product photos?

Yes. Enable the Auto-Sample Eye Dropper to sample edge pixels from supplier photos (e.g. #F8F9FA off-white) so the canvas padding blends seamlessly without visible seam borders.

Are my high-resolution product photos uploaded to a third-party server?

No. All canvas transformations, pixel padding, and ZIP packaging execute 100% client-side in your browser memory. Your proprietary product photography remains strictly private.

BLUF • Direct Reference Rule

Non-destructive canvas scaling calculates bounding dimensions via scale = min((Target_Width × (1 - 2 × padding)) ÷ Source_Width, (Target_Height × (1 - 2 × padding)) ÷ Source_Height), with centered coordinates posX = (Target_Width - Source_Width × scale) ÷ 2. For Shopify product grids, pad raw supplier images onto uniform 2048×2048 square WebP canvases to eliminate jagged collection alignments.

📖 Terminology Decoded (Plain-English Glossary)

Beginner Friendly

● Aspect Ratio (1:1 Square)

The mathematical relationship between width and height. A 1:1 ratio is a perfect square, creating uniform, aligned product cards across store grids.

● Canvas Padding

The clean white or transparent border buffer placed around a photo so rectangular images become square without cutting off the product.

● WebP Format

Google's modern web image format that shrinks file sizes by 30% compared to JPG without losing visual sharpness on mobile and Retina screens.

● 2048 × 2048 Master

Shopify's recommended square resolution that enables crisp customer zoom and pinch-to-zoom on product display pages.

● Edge-Sampling Background

An algorithm that samples the outermost pixel color of a supplier photo to fill outer margins seamlessly without mismatched seams.

● Client-Side Processing

Images are resized and converted directly inside your browser using HTML5 Canvas with zero images uploaded to any remote server.

Mathematical Equation

Price = [COGS + Shipping + CPA + $0.30 - (ShipCharged × 0.971)] ÷ (1 - 0.029 - TargetMargin%)

Country-Specific Regulatory & Operational Rules

Stripe US / Shopify Payments base rate: 2.90% + $0.30 per successful charge.
Statutory Processing Tax: 0% VAT/GST on payment processing fees.
