What it does
Every other free PDF tool uploads your file and promises to delete it later. LightUtils cannot upload it. The site ships a Content Security Policy with connect-src 'none', so the browser itself forbids this page from making any network request. Verify it in DevTools in ten seconds. 36 tools for PDF, image, video, audio and CSV. No account, no watermark, no daily limit, no size cap, because there is no server cost per file. Full English and Thai.
Free tools that run in your browser: compress and merge PDFs, shrink video, convert images, clean up audio, generate QR codes. Nothing is uploaded, ever.
Nothing is uploaded. Nothing is stored. Nothing costs money. 57 tools for PDF, images, video and CSV. Every one of them finishes in this tab, on your own machine. Convert to WebP, JPEG or PNG, resize, and cut the file size. The photo never leaves your device. Crop to any size or aspect ratio, by dragging or by typing exact pixels. The photo never leaves your device. Cut a subject off a single-colour background and save it as a transparent PNG. Nothing is uploaded. Photos, screenshots and PDFs into a single document, in the order you choose. Photos and screenshots into one PDF, in the order you choose. Nothing is uploaded. Join PDFs into one, in the order you choose. Nothing is uploaded.…from lightutils.com

Clipto MCP▲655Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy.
