Compress an image to 500 KB
For passport photos, job applications, government forms and email. Pick a photo — it is resized and compressed right here on your device. Nothing is uploaded.
Target: · output is JPG
Whole folders, PNG/WebP, or let your AI do it?
GUI Hub Essentials compresses and resizes entire folders at once, keeps your originals, outputs JPG, PNG or WebP, and can be driven by Claude or Cursor (“make every photo in this folder under 500 KB”). 3 free uses; $9 once.
How it works
Your browser redraws the photo and tries lower JPEG qualities (and, if needed, smaller dimensions) until the file is under 500 KB, keeping the best quality that fits. It works offline once the page has loaded.
