A deep dive into everything SaveAs+ can do.
One-Click Format Conversion

- Works with <img> tags, CSS background images, and canvas elements
- Converts using the browser's native Canvas API for maximum speed
- Supports images from any origin via Chrome extension permissions
- Automatically handles CORS and cross-origin image fetching
Format | Size | Dimensions | Scale
Smart Hover Overlay
Hover over any image to see its real format, natural dimensions, displayed dimensions, file size estimate, and scale factor. The overlay appears in a sleek, non-intrusive tooltip.
- Shows original format (PNG, JPG, WebP, GIF, AVIF, SVG, etc.)
- Displays natural width x height vs rendered dimensions
- Estimates file size from the image source
- Shows display scale (e.g., 2x for retina images displayed at half size)
Four Output Formats
Choose between four image formats to match your exact needs. Whether you're saving a screenshot, a photo, or optimizing for web — there's always the right option.
- PNG: Lossless compression, perfect for screenshots and pixel art
- JPG: Lossy compression, ideal for photographs with small file sizes
- WebP: Modern format with excellent quality-to-size ratio
- AVIF: Next-generation format with the best compression available
Privacy First
SaveAs+ processes everything 100% locally in your browser. No image data, browsing activity, or personal information ever leaves your machine. We can't see what you save — and we don't want to.
- Zero network requests to external servers
- No analytics, telemetry, or usage tracking of any kind
- No cookies, no accounts, no sign-up required
- All conversion uses the browser's built-in Canvas API
Smart Filename Preservation
SaveAs+ tries to preserve the original filename when saving. No more 'download.png' or 'image(1).jpg' cluttering your Downloads folder. You get clean, descriptive filenames by default.
- Extracts filename from the image URL path
- Strips query parameters and hash fragments
- Appends the correct extension based on your chosen format
- Falls back to a descriptive name when the URL has no filename
Transparency Handling
When converting transparent images to JPEG (which doesn't support transparency), SaveAs+ automatically composites the image onto a white background. No unexpected black backgrounds.
- Detects transparent pixels before JPEG conversion
- Applies a clean white background fill automatically
- Preserves transparency when saving as PNG, WebP, or AVIF
- No visual artifacts from alpha channel removal
