Free Online Image Converter — WebP & AVIF
ImageForge is a completely free, browser-based image converter and optimizer that converts PNG, JPG, JPEG, GIF, BMP, TIFF, SVG, and WebP images to modern formats like WebP and AVIF. All processing happens directly in your browser — your images never leave your device.
Why Convert Images to WebP or AVIF?
Modern image formats like WebP and AVIF dramatically improve website performance. WebP images are typically 25–35% smaller than equivalent JPEG or PNG files at the same quality level. AVIF, the newest format, achieves even better compression — often 50% smaller than JPEG — with superior quality at lower file sizes. Both formats are now supported by all major browsers.
WebP Format Benefits
WebP supports both lossy and lossless compression, transparency (like PNG), and animation (like GIF). It's developed by Google and is the most widely supported modern image format. Converting your images to WebP is one of the easiest ways to improve Core Web Vitals scores and page loading speed.
AVIF Format Benefits
AVIF (AV1 Image File Format) is based on the AV1 video codec and offers exceptional compression efficiency. It supports HDR, wide color gamut, transparency, and both lossy and lossless modes. AVIF is especially beneficial for photography and complex images where quality preservation matters most.
How to Use the Image Converter
1. Drag and drop your images into the upload zone, or click "Browse Files" to select them. You can also paste images from your clipboard using Ctrl+V (or Cmd+V on Mac). 2. Choose your output format — WebP or AVIF. 3. Adjust quality settings (85 is recommended for most use cases). 4. Click "Convert All" to process all images. 5. Download individual files or all converted images as a ZIP archive.
