toolsholic is a collection of 130+ everyday tools — PDF editing, image compression, file conversion, text comparison, developer utilities, calculators and business documents — that all run entirely inside your browser. Nothing you open is ever uploaded. There is no server doing the work, so your file simply never leaves your machine. You can confirm it by turning off your internet: every tool keeps working. What is in it: · 45 PDF tools — merge, split, compress, rotate, crop, sign, redact, watermark, page numbers, repair · 30 image tools — compress, resize, convert, crop, upscale · 13 developer utilities — JSON formatter, regex tester, JWT decoder, hashing, encoding · 11 converters, 11 text tools, 10 calculators, 9 business document generators Why it is built this way: Most "free" online tools upload your file, add a watermark, cap your file size, or ask you to sign up. All of those exist because processing files on a server costs money and needs recovering. If the processing happens on your own device, none of it is necessary — so there is no watermark, no daily limit, no account, and no catch. It also means it works on a plane, and there is nothing for a corporate network to object to, since no data is transmitted at all. You can pin the tools you use to the top of the homepage, and request anything that is missing. Free, no sign-up, and it stays that way.
