kbmjj123/BulkPicTools ? reverse-engineered prompt

Build me a simple, polished website for a privacy first batch image tools app.

It should let people drag and drop a lot of images, then crop, compress, resize, rotate, flip, or convert them right in the browser without uploading anything. Make the experience feel fast and easy, with clear sections for the main tools like bulk image cropper, compressor, and converter, plus a few common presets like JPG, PNG, WebP, HEIC, passport photo, 2x2, Instagram, Facebook, and YouTube thumbnail sizes.

I want the page to explain that everything runs locally and offline, and that files never leave the device. Include a clean homepage, a tools grid, helpful instructions, and a download area for the finished files. Keep the design modern and friendly, with good mobile support and room for lots of images at once. If you need to check current browser or image handling docs online, feel free to.
