A PDF toolkit that keeps every document inside the browser.

Context

Online PDF tools usually require users to upload documents to a remote server. That model creates avoidable friction for contracts, administrative documents, financial files, and other sensitive material.

CompressMyPDF is an Appik Studio product for editing PDFs without transferring the source file away from the user's device.

What we built

• A multilingual web application for PDF compression, conversion, merging, splitting, and rotation.
• A browser-side processing pipeline powered by WebAssembly and Ghostscript.
• A responsive workflow for desktop and mobile browsers, with no account required.
• Clear privacy messaging that explains where and how each document is processed.

Local browser processing

The processing pipeline runs locally in the browser. The selected PDF is read into browser memory, processed by a Web Worker, and returned as a downloadable file. The document itself is not uploaded to an Appik Studio or CompressMyPDF server.

This architecture keeps the product useful for privacy-conscious workflows while avoiding the storage and retention questions created by a conventional upload API.

Product outcome

Users choose a file, select an operation, and download the result from the same browser session.

The tool is free, requires no account, and is available in five languages.
