Frequently Asked Questions

Are my PDF files uploaded to a server?

No. All PDF processing — merging, splitting, compressing, and converting — happens entirely in your browser using JavaScript. Your documents never leave your device.

What's the maximum file size for PDF tools?

Since everything runs in your browser, the limit depends on your device's memory. Most modern devices handle PDFs up to 100MB without issues. For very large files, try splitting them first.

Can I merge more than 2 PDFs at once?

Yes. You can merge as many PDFs as your browser can handle. Drag and drop multiple files, reorder them, then merge into a single document.

Does PDF compression reduce quality?

Quickr's compression optimizes file size while maintaining readable quality. Text remains crisp. Images are recompressed at a quality level that balances size reduction with visual clarity.

Do the PDF tools work offline?

Yes. Once the page has loaded, all operations work without an internet connection. This makes Quickr ideal for working on sensitive documents in offline environments.
