What it does
Most online image tools force you to upload your sensitive passports, IDs, and tax documents to a random cloud server. You have no idea who is storing your data or where it goes. GASO Studio is different. We built a suite of professional image tools—including Smart Compress, Biometric Crop, ID Combiner, and Format Converter—that run 100% locally in your web browser using WebAssembly (WASM). Your files never leave your device, meaning your sensitive IDs and personal photos stay private, forever.
Edit PDFs, extract tables to Excel, compress, resize, and convert images directly in your browser. Zero server uploads. 100% private and offline.
Resize, merge, format, convert, etc.—build your perfect workflow locally at lightning speed. Zero server uploads. 100% private. Reduce file size to exact KB while maintaining maximum visual fidelity. AI face detection aligns passport, visa, and ID photos to strict standards. Pack multiple passport, visa, and ID photos onto A4 or 4x6 paper for printing. Seamlessly merge the front and back of your ID into a single print-ready document. Add text, signatures, and annotations to your PDF documents securely in your browser. Merge multiple PDFs, split documents, delete pages, and rotate. Change dimensions, aspect ratios, or add white padding for e-commerce. Instantly convert HEIC, WEBP, PNG, and…from gasostudio.com

Homebrew 6.0.0▲1,481Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
