Hey HN I built ImageConverter.dev because I got tired of “free” image converter sites that force uploads, or throttle conversions. So I made a tool that runs 100% client-side — meaning your images never leave your device. It’s built for speed, simplicity, and privacy. What it does Convert images between JPG, PNG, WebP Works offline once loaded (PWA support) How it works It uses the Canvas API and WebAssembly to handle conversions directly in the browser. There’s no upload, no tracking, no server costs, and it’s fast even on mid-range devices. Why I built it I wanted an instant, no-ads,…

Hi HN, I’m Linn, the creator of ToolKuai (https://toolkuai.com). Like many of you, I’ve always been wary of "free" online file converters. Most of them are black boxes: you upload your private documents or images to a remote server, and you have no idea where that data ends up or how it’s being used to train models. I wanted to build a suite of tools (Video/Image compressor, OCR, AI Background Remover) that runs entirely in the browser. No files ever leave your machine. The Tech Stack To make this performant enough to rival server-side processing, I leaned heavily into modern…

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…

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…

Picture Kit▲10I’ve been working on a side project for a while and wanted to share it with the HN community to get feedback. The idea started simple: I wanted to do batch image processing entirely in the browser without uploading anything to a server. Most existing tools were either cloud-based (privacy concerns, slow for large batches) or desktop apps that were hard to automate and combine into workflows. A big source of inspiration was macOS Automator. I really liked how you could chain small actions into repeatable workflows, and I wanted something similar for image processing on the web. At first it…
