PixelDOC - Images & Docs File Optimizer

100% Offline Image, PDF & Document compressor, converter & target size scaler. Compress to exact KB/MB without quality loss.

PixelDOC is an all-in-one browser tool designed to compress, resize, and optimize images, PDFs, and documents directly on your computer. Many government portals, job application forms, and educational websites enforce strict file size limits (such as requiring uploads under 100 KB or 500 KB). PixelDOC solves this challenge with precision target-size scaling and on-device processing. Unlike standard web converters that transfer confidential documents to remote cloud servers, PixelDOC functions entirely within your browser. None of your data or files ever leave your device. Key Capabilities: Exact Target Size Compression Specify a custom target file size in kilobytes or megabytes. PixelDOC automatically calculates the optimal compression balance to ensure your file meets strict upload thresholds without unnecessary quality loss. File Size Increaser & Padding Some submission portals require files to meet a minimum size requirement. PixelDOC can safely adjust file sizes to satisfy upload criteria while preserving document integrity. Side-by-Side Visual Comparison Inspect image sharpness and compression fidelity before downloading. The built-in dual-layer slider divider lets you compare the original and optimized previews side-by-side. Batch Workstation Process multiple files at the same time using the fullscreen workstation. Optimize entire queues and save your finished items individually or as a single ZIP archive. Universal Format Support Easily convert between popular image types, document formats, and spreadsheets right inside your browser session. On-Device Privacy & Security All processing runs locally through modern client-side browser engines. PixelDOC also strips sensitive camera metadata and geolocation tags from images before saving, and continues working even when completely offline. Ideal for job applicants submitting resumes, students uploading coursework, and professionals handling confidential records.
