Convert images to WebP, JPEG, PNG, AVIF, or ICO instantly with visual comparison and zero server uploads.
Upload single or multiple images (JPEG, PNG, WebP, GIF, AVIF, ICO up to 50 MB each).
Selecting the right image format involves understanding structural capabilities:
| Format | Compression Type | Alpha Transparency | Animation | Primary Use Case | |---|---|:---:|:---:|---| | WebP | Lossy & Lossless | ✅ Yes | ✅ Yes | Modern web production (25–35% smaller than JPEG/PNG) | | AVIF | Advanced Intra-frame | ✅ Yes | ✅ Yes | Next-generation web imagery with extreme byte efficiency | | PNG | Lossless (Deflate) | ✅ Full 8-bit Alpha | ❌ No | UI icons, vector logos, and screenshots requiring pixel precision | | JPEG | Lossy (DCT) | ❌ No | ❌ No | Photographs and complex gradients where small size matters | | GIF | Lossless (LZW 256 Color) | ✅ 1-bit Index | ✅ Yes | Simple web animations and retro graphics | | ICO | Uncompressed / PNG | ✅ Yes | ❌ No | Browser favicons and Windows desktop application icons |
When converting from formats with alpha transparency (PNG, WebP) to formats that do not support transparency (JPEG, BMP), our engine prevents black-box artifacts by automatically compositing the image over a clean white background.
Scenario: Optimizing a transparent company logo for a Next.js production website.
File: company_logo.png (Size: 1.2 MB, PNG-24 with Alpha)
Converted: company_logo.webp (Size: 145 KB, 87.9% Savings, Alpha Intact)
Preserves clean transparent background while drastically reducing file weight.
Scenario: Converting a downloaded WebP image for compatibility with legacy desktop print software.
File: product_render.webp (Size: 320 KB)
Converted: product_render.jpg (Size: 450 KB, 100% Compatibility)
Generates a universally compatible JPEG with white background fill.
Compress JPEG, PNG, WebP, AVIF, and GIF images locally in browser memory. Reduce file sizes by up to 85% with zero quality loss or server uploads.
Resize image width and height dimensions by exact pixels, percentages, or social media presets with aspect ratio locking and bicubic resampling.
Convert images between WebP, PNG, JPEG, AVIF, GIF, BMP, and ICO formats in batch with alpha channel protection and quality control.
Crop images with custom aspect ratio bounding boxes (1:1, 16:9, 4:3, 9:16), circular avatar masks, and rotation controls in real time.
Pick exact pixel colors from any uploaded image with a precision magnifier loupe, HEX/RGB/HSL conversions, and WCAG contrast analyzer.
Extract dominant color palettes, harmonious swatches, and UI themes from photos and graphics using Median Cut and K-Means color quantization.
Add customizable text and logo watermarks to photos in batch with opacity controls, tile patterns, font styling, and drag-and-drop positioning.
Generate complete website favicon packages including multi-resolution ICO files, Apple Touch icons, Android Chrome icons, and HTML header tags.
Convert images (PNG, JPG, SVG, WebP, GIF) into Base64 Data URIs for inline HTML/CSS, or decode Base64 strings back to downloadable image files.
Inspect image width, height, aspect ratio, megapixels, DPI, color space, and camera EXIF metadata with privacy privacy warnings in real time.
