Frequently Asked Questions
Are PaperPilot tools completely free to use?
Yes. All 17 PDF tools on PaperPilot are 100% free with no hidden fees, paid tiers, or required account sign-ups.
What file formats are supported?
PaperPilot supports standard PDF (.pdf) documents, as well as JPG, JPEG, PNG, and WebP images for conversions, form filling, text diffing, and page extraction.
What is the maximum file-size limit?
For optimal in-browser memory performance and device responsiveness, we support files up to 100 MB per PDF and 50 MB per image.
Are my documents uploaded to a remote server or cloud?
No. All PDF processing (compressing, merging, splitting, watermarking, rotating, converting, and text diffing) runs completely in your web browser's memory using WebAssembly and JavaScript. Your documents remain safely on your personal device.
How does PDF compression work here?
Our compression engine optimizes PDF object streams, cleans redundant metadata, and re-encodes embedded raster images according to your chosen compression preset. If a PDF is already compressed vector text, we preserve its original quality without degradation.
Does PaperPilot work on mobile devices and tablets?
Yes. PaperPilot is designed to be fully responsive and works smoothly across mobile Safari, Google Chrome, Firefox, and tablet browsers without installing any app.
Why might a PDF occasionally fail to process?
A file might fail if it is encrypted with a password, corrupted, or contains malformed internal objects. We recommend removing password protection or opening and re-saving the file prior to running tools.
