24 alternatives to ToolKuai – Privacy-first, 100% client-side media tools
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…

Hello HN, I've used a lot of image converter websites to run for my daily jobs, but they required uploading my assets on their servers which I didn't like. I decided to build it myself and publish as a website for everyone to use at no cost (since the conversion happened on your browsers) I'd live to hear your thoughts about it. Cheers,

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…

Hi HN! I've created [UFreeTools](https://www.ufreetools.com/), a collection of developer utilities (60+ tools and growing) that's completely free, ad-free, and runs entirely in the browser. No data leaves your device - everything is processed locally. ## Background As a developer, I found myself constantly searching for simple utilities like JSON formatters, UUID generators, and color pickers. Most existing options were cluttered with ads, required sign-ups, or sent data to servers. I wanted clean, fast tools that respected privacy. So I built UFreeTools as a modern SPA using…

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…
