Is RefineDoc really free to use?expand_more

Yes, RefineDoc is 100% free with no hidden charges, subscription requirements, or daily limits. We built this as a utility-first tool for everyone.

How does 'no upload' compression work?expand_more

We use WebAssembly which allows your browser to run high-performance code. The compression engine runs locally in your browser tab, processing the file without ever sending data to a server.

Will the quality of my PDF decrease?expand_more

Our 'Recommended' setting is designed to find the perfect balance. It optimizes image resolution and removes unnecessary metadata while keeping text crisp and vector graphics sharp.

Are my files safe?expand_more

Absolutely. Since your files never leave your computer, no one else can see or access them. This makes RefineDoc safer than traditional cloud-based converters.

Is there a file size limit?expand_more

There are no artificial limits. The only limit is the available RAM on your device, meaning you can often compress files that cloud services would reject for being too large.

Can I use RefineDoc offline?expand_more

Yes! Once the page is loaded, the tool works completely offline since all the processing happens in your browser locally.
