hey folks! been building this collection of free tools over the past week or so. started with just JSON formatter and regex tester, kept adding stuff people asked for.
the most recent addition is an EXIF metadata viewer/remover β drop in a photo and it shows you all the hidden data (GPS, camera model, etc) then lets you download a clean copy. kinda crazy what photos leak tbh.
everything runs client-side β no server, nothing uploaded, no tracking. built with vanilla html/css/js, hosted on github pages. code's a bit messy but it works π€·ββοΈ
would love feedback on what tool to build next. thinking maybe a file hash generator or SSL cert checker?
