FlashKit Tools is a free collection of browser-based utilities. Compress, merge, split and convert PDFs; compress images, remove backgrounds and generate QR codes; run India finance calculators for EMI, SIP, FD, PPF, RD, gratuity, income tax, GST and invoices; plus developer helpers such as a UTM builder, SQL formatter and binary converter. Most file tools process in the browser, and a few use outside services, which the site discloses. No account is required, and the site is ad-supported.
Needed private, no-signup PDF and image tools and India finance tools that work in the browser.
