Use Claude Code to Convert Files Instead of Sketchy Online Tools
Next time you need to compress a PNG or convert a webm to MP4, don't reach for a shady online converter and upload your files to a random website. Claude Code has full terminal access — just ask it to do the conversion locally using the tools already on your machine.
# Compress a PNG using macOS built-in sips
sips -Z 1200 image.png --out image-compressed.png
# Convert webm to mp4 with FFmpeg
ffmpeg -i video.webm -c:v libx264 -c:a aac output.mp4
# Resize a whole folder of images at once
sips -Z 800 *.jpg
Just describe what you want in plain English: "compress this PNG to under 500KB" or "convert all webm files in this folder to mp4 and keep the audio". Claude picks the right tool, constructs the flags, and runs it — no fumbling with command syntax required.
This works for image resizing, format conversion, video transcoding, audio extraction, PDF manipulation, and more. If there's a CLI tool that handles it, Claude Code can run it.
No uploads. No trust issues. No sketchy browser extensions. Everything stays on your machine.
If you need a tool that isn't installed, ask Claude to install it first — it can handle that too.

Set up Claude Code as an automated reviewer in your CI pipeline — on every pull request, it reads the diff, checks for bugs, security issues, missing tests, and convention violations, then posts its findings as a PR comment. Your human reviewers get a head start because the obvious issues are already flagged before they look.
Before deploying, tell Claude to read your project — migrations, environment variables, queue workers, scheduled tasks, caching, third-party integrations — and generate a deployment checklist that's specific to your app. Not a generic "did you run migrations?" list, but one that knows YOUR infrastructure and catches the things YOUR deploy can break.
Instead of writing a README from memory or copying a template, tell Claude to read your project and generate one that's actually accurate — real setup instructions from your config, real architecture from your directory structure, real API examples from your routes, and real prerequisites from your dependency files.
