Free Image Tools

Use the Image Resizer tool to set exact pixel dimensions for each platform: 1080x1080 for Instagram posts, 1200x630 for Facebook/LinkedIn shares, 1500x500 for Twitter headers, and 1280x720 for YouTube thumbnails. The tool uses browser-native canvas rendering to maintain quality during resizing. For best results, start with an image larger than your target size and scale down rather than up.

WebP offers the best balance of quality and file size for web images, with 25-35% smaller files than JPEG at equivalent quality. Use WebP for photographs and complex images, SVG for logos and icons (infinitely scalable, tiny file size), and PNG only when you need transparency with no quality loss. The AIBox image converter tools let you switch between formats instantly in your browser.

Use the Favicon Generator to create favicons from text, emoji, or uploaded images. Modern browsers need a 32x32 ICO file for the tab icon and a 180x180 PNG for Apple touch icons. The generator produces all required sizes. For best results, use a simple design with high contrast since favicons display at very small sizes.

Yes. The Image Compressor uses browser-based encoding to reduce file sizes by 40-70% with minimal visible quality loss. JPEG images can typically be compressed to quality level 80 (out of 100) without noticeable degradation. PNG files can be reduced by stripping metadata and optimizing color palettes. All compression happens in your browser so your images are never uploaded to a server.

All image tools on AIBox process files entirely in your browser using HTML5 Canvas and JavaScript APIs. Your images are never uploaded to any server. You can verify this by disconnecting from the internet and using the tools offline (after the page loads). This makes them safe for processing private photos, screenshots with sensitive information, and proprietary design assets.
