Compression Performance
CrunchPix uses the browser-image-compression library with a configurable quality slider (1 to 100). The `initialQuality` parameter maps directly to the slider value divided by 100, and compression runs in a single iteration (`maxIteration: 1`) to prioritize speed.
Key characteristics:
Actual compression ratios depend on the source image, chosen format, and quality setting. Converting a large PNG to WebP at quality 60, for example, typically yields a 70-85% reduction. JPEG-to-JPEG at quality 80 typically yields 30-50% reduction depending on the original's compression level.

FormatFlip accepts 10 input formats but outputs only 3 (PNG, JPG, WebP). CrunchPix handles 4 input formats with 3 output options. SvgMint is SVG-only on input but can rasterize to 4 formats plus optimized SVG output.
Resizing Capabilities
SizeCraft provides 48 built-in presets organized across 10 platform categories: Instagram, YouTube, Twitter/X, LinkedIn, Facebook, TikTok, Pinterest, E-commerce, Email, and Ads. Six presets are available on the free tier (Instagram Post, Instagram Story, YouTube Thumbnail, X Post, LinkedIn Post, and Facebook Post). The remaining 42 presets plus custom dimensions require Pro.
Four crop modes are supported:
1. Center crop -- Crops from the center of the image to fit the target dimensions
2. Fill color -- Places the image on a solid-color background, maintaining the full image within the frame
3. Blur fill -- Fills empty space with a blurred, enlarged version of the source image
4. Smart crop (Pro) -- Uses the browser's FaceDetector API to center the crop on detected faces
Additional Pro features include WebP and AVIF output, 2x retina exports, quality controls, multi-image runs (up to 20 images), custom presets, and ZIP download.
