Vimzify brings 183 genuinely useful tools together in one place, organised into eight categories so you can find the right one in seconds. Every tool runs entirely in your browser โ nothing is uploaded to a server โ which means your images, documents and text stay private, and results appear instantly with no waiting in a queue.
Image Tools cover the jobs people do every day: converting between JPG, PNG, WebP and AVIF, compressing photos for websites, resizing and cropping for social media, and extracting colour palettes. PDF Tools merge, split, rotate and convert PDFs without the watermark traps of typical โfreeโ sites.
Calculators handle everything from BMI, age and loan payments to scientific and unit conversions. Text Tools include the word counter, case converter and text-to-speech, while Developer Tools cover JSON formatting, Base64, hashing, UUIDs and regular expressions. SEO & Web Tools and the Utility category round out the set with generators, checkers and everyday helpers.
