Free Online Image Compressor — Compress PNG, JPEG, WebP & HEIC
ImageCompress is a free, browser-based image compression tool that reduces file sizes without uploading your images to any server. All processing runs 100% client-side using WebAssembly and MozJPEG, so your photos stay private on your device. Compress PNG, JPEG, WebP, and iPhone HEIC images instantly with no sign-up required.
Smart Compression Modes
Choose from three modes: Auto mode detects whether your image is a photo or graphic and picks optimal settings. Manual mode gives you full control over compression quality from 1% to 100%. Target mode lets you set a maximum file size in KB — perfect for email attachments, website uploads, or social media posts with strict size limits.
Batch Processing & Resize
Upload multiple images at once to compress them in batch. Download all results as a single ZIP file. Resize images before compression by percentage or exact pixel dimensions with aspect ratio lock. Strip EXIF metadata to remove GPS location and camera data for smaller files and better privacy.
iPhone HEIC to JPG Conversion
Drag and drop HEIC photos from your iPhone or iPad. They are automatically converted to JPEG and compressed in your browser. On Safari, HEIC files are decoded natively for faster processing. No app installation needed — works on any device with a modern browser.
Privacy & Security
Unlike other online image compressors, ImageCompress never uploads your files. Your images are processed entirely in your browser using WebAssembly-powered MozJPEG encoding. No server, no cloud storage, no data collection. Your photos remain completely private and secure on your device.
