Tips for a clean merge
- Rotate sideways scans first with https://thetoolss.com/tool/rotate-pdf
- Compress a huge result with https://thetoolss.com/tool/compress-pdf

Privacy vs typical “upload and wait” sites
Many popular PDF sites upload your document to a remote server. TheToolss is built so core PDF merges stay on your device in the browser. That is better for sensitive invoices, ID scans, and school work.
