OpenHow to choose
Two operations that sound similar can produce very different files. Before starting, decide whether selectable text, transparency, aspect ratio, metadata, links or a digital signature must survive.
Merging and splitting copy pages; image conversion renders their appearance; compression can rewrite resources and, in demanding cases, rasterise. Keep the source when signatures, forms, outlines or accessibility matter.
Resizing changes pixel dimensions, while compression and conversion change how pixels are stored. For the web, it is usually most effective to set the right dimensions first and then adjust format and quality.
A random password still needs a manager and MFA. A QR code needs a physical test and a stable destination. Reviewed guides include these checks so the output remains useful beyond this screen.
All 65 tools in the public catalogue have a dedicated guide in English and Spanish. Identifier, IBAN and payment-card generators produce synthetic validation data only and display clear usage limits; languages without editorial review remain outside the index.
