24 alternatives to Merge JPG – Privacy-first and fast image merging tool
Hi HN, I built https://mergejpg.me – a client-side image merging tool that combines multiple JPG images directly in your browser without any server uploads.

The Solution: Complete client-side processing using modern browser APIs. Your images never leave your device. Technical Details: - Built with Next.js 15 and TypeScript - Uses HTML5 Canvas API for image manipulation - Progressive loading for…

Hi HN, I have been working on a set of PDF tools that does all the processing directly in the web browser. From time to time I needed to do some simple PDF manipulations like merging PDF files. Sometimes the files contain my personal data and I was not comfortable using other online services where the file usually is uploaded to a remote server. Behind the scenes there is a small library written in C++ doing the changes to the PDF files. I am using the Emscripten compiler to compile it to WebAssembly that is running in the browser. It was a very good learning for me and it was easier than I…

Smallimg▲7Hi HN, I built a free image compression tool called Smallimg.cc that runs entirely in the browser. The main motivation was privacy. I was never comfortable uploading potentially sensitive images to a third-party server just for compression. This tool solves that by using JavaScript and WebAssembly to perform all the processing on the client-side. Your files are never transferred over the network. Key features: Total Privacy: Your images never leave your computer. Incredible Speed: No upload/download time, just instant processing. Full Control: You can adjust quality, resize, and convert…

Pahadify▲12Hello HN, I am a solo developer based in INDIA. I wanted to share Pahadify, a lightweight image editing utility I've been working on. The Problem: I was tired of simple image tools that require uploading private files to a server or downloading heavy 500MB+ software just for basic edits. The Solution: I built this as a completely client-side PWA (Progressive Web App). Technical Details: Stack: Pure HTML, CSS, and JavaScript (No heavy frameworks). Size: The entire application is approximately 1.5MB. Privacy: All processing happens in the browser; no image data is sent to a backend. I built…

It’s fast, free, and doesn’t require any sign-up. Just upload your files, and it merges them into one clean JSON output. I made this because I kept running into small but annoying JSON merging tasks while working on side projects — especially when dealing with API responses, config files, or datasets. Most existing tools were either CLI-only, full of ads, or had weird size limits. So I built my own.
