Privacy-focused browser-based image converter with batch processing and offline support
Published Mar 21, 2026
🔴 Problem Identified
People need to convert image formats (especially HEIC from iPhones) but don't want to upload private photos to unknown servers. Existing online converters require file uploads, raise privacy concerns, and often don't support newer formats like HEIC. Users also need batch processing capabilities for multiple images.
💡 Proposed Solution
A web application that uses WebAssembly to convert and compress images entirely in the browser. Supports multiple formats including HEIC, processes up to 200 images in batches, works offline as a PWA, and includes quality comparison tools. No uploads, accounts, or server processing required.
