What counts as an operation?
An operation is one completed use of a tool, such as merging a set of PDFs, compressing one PDF, or resizing one image. Browsing tools, selecting files, changing settings, validation errors, and failed processing do not use an operation.

Processing and current limits
This supported operation runs in your browser after you select an input. Free use allows 25 MB files and shares 20 completed operations per day across tools. Pro removes those product limits, but browser memory and device performance can still limit large files.
Review security and data handling and current limits before processing a sensitive or important original.
