DigiKitApp is a free online toolkit for merging PDFs, editing images, developer utilities, SEO checks, and calculators. It's built for individuals and small businesses; no account is needed and files are never uploaded to a server, everything runs directly in your browser.

What does DigiKitApp do?

With DigiKitApp's 172 free tools you can merge, split, and compress PDFs; resize images, convert formats, and remove backgrounds; use developer tools like JSON, regex, and hash generators; and run calculators for VAT, income tax, net-to-gross salary, and other Turkey-specific and everyday needs.

Are my files safe?

Almost every DigiKitApp tool processes your file in your browser; PDFs, images and text are not uploaded to a server, and nothing is left behind when you close the page.
