Image conversion, compression, and editing — 13 free tools, all processing client-side for maximum privacy. No sign-up, no limits, no data collection.
CodelithLabs Image Tools let you resize, compress, crop, convert, and filter images entirely in your browser using the Canvas API and Web Workers. Your images never leave your device — perfect for sensitive or proprietary visuals.
Image processing is typically associated with heavy desktop software like Photoshop or server-dependent online tools that upload your photos to remote servers. CodelithLabs Image Tools break this pattern by running every operation directly in your browser using the HTML5 Canvas API and Web Workers for non-blocking performance.
Our Image Compressor uses intelligent quality reduction algorithms to shrink JPEG and PNG files by up to 80% while maintaining visual fidelity — essential for web developers optimizing page load times and meeting Core Web Vitals thresholds. The Image Resizer supports exact pixel dimensions, percentage scaling, and preset social media dimensions (Instagram square, Twitter header, Facebook cover, LinkedIn banner). Image Cropper offers freeform and fixed-ratio cropping with real-time preview.
Format conversion tools handle JPG-to-PNG, PNG-to-JPG, and Image-to-Base64 transformations instantly — useful for embedding images in CSS, emails, or data URIs. Our Image Filters apply artistic effects using Canvas pixel manipulation: grayscale, sepia, blur, brightness, contrast, and saturation adjustments with live preview. The Privacy Blur tool lets you redact faces and sensitive regions before sharing screenshots, and the Image Watermark tool overlays custom text or logos with adjustable opacity and positioning. All processing is 100% client-side — your images never leave your device.
