What it does
ShrinkPDF is a set of 7 free PDF tools (compress, merge, split, rotate, convert to images, reorder pages) that run entirely in your browser. Nothing is ever uploaded to a server, which matters when you're compressing a payslip, tax filing, or signed contract. No signup, no file size caps, no watermark, no premium tier. Open the page, drop your file, and it's processed instantly on your own device using pdf-lib, an open source library.
Compress large PDF files for free. No file size limit. No login required. Files processed locally — never uploaded to any server.
Reduce PDF size by up to 80% — free, with no file size limit. Unlike Smallpdf or iLovePDF, your file never leaves your browser . No upload. No server. Completely private. ⚠️ This PDF could not be compressed further — it may already be optimised. Try switching to a stronger compression level. Actual file sizes from documents users commonly compress — tested in-browser, no server involved. Results vary by document type and content. Image-heavy files compress more; text-only PDFs compress less. Why? → Not sure which compression level to use, or why your PDF is so large in the first place?

Talanoa▲343Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

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!
