Why Use This Platform?

Verifiable Local Privacy & Binary Precision

Most online converters upload your confidential shipping labels, family photos, and CSV databases to remote server queues. Vexolora processes your files directly inside your browser's volatile memory (RAM) using standard Web APIs (ArrayBuffer, DataView, DOMParser, and HTML5 Canvas).

✓ Zero Server File Storage: Core tools never upload your files—verify it yourself in your browser's Network tab.
✓ True Binary Header Editing: Our 300 DPI Scrubber writes 9-byte PNG pHYs chunks and JPEG JFIF headers without re-encoding pixels.
✓ Batch & ZIP Ready: Process up to 100 images at once and download a single standards-compliant ZIP archive.

Standard Image Sizes & Aspect Ratios for Instagram, YouTube Thumbnails, and Etsy Listings

Uploading the wrong aspect ratio to Instagram, YouTube, or Etsy causes automatic platform cropping that cuts off product edges or text overlays. Below is the quick-reference dimension matrix built directly into the Vexolora Image Resizer and 1080×1080 Square Resizer.

1. Master Social & Marketplace Dimension Table

Platform & Placement	Pixel Dimensions	Aspect Ratio	Recommended Format
Instagram Square Post / Carousel	`1080 × 1080 px`	1:1	JPG (Quality 92)
Instagram Story / Reels / TikTok Cover	`1080 × 1920 px`	9:16	JPG / PNG
YouTube Video Thumbnail	`1280 × 720 px` (under 2 MB)	16:9	JPG / PNG
Etsy & Shopify Zoomable Product Photo	`2000 × 2000 px`	1:1	JPG (sRGB)
8×10 in Print-on-Demand Artwork (300 DPI)	`2400 × 3000 px`	4:5	PNG (300 DPI pHYs)

2. Avoid Distortion with Keep Ratio + White Pad

When resizing a vertical product shot into a 1080×1080 or 2000×2000 square in our Image Resizer, keep Keep Ratio + White Pad enabled. If your product photo also needs its studio backdrop cleaned up first, run it through the Background Remover.
