Browser PDF tools vs server PDF tools
Browser PDF tools keep processing on your device, while server PDF tools upload files temporarily for tasks that need stronger rendering or optimization. FreePDFHelp labels both modes clearly.

Browser-local tools are best for page organization and JPG to PDF conversion. Server tools are used when output quality, validation, compression, or rendering requires native PDF processing.
Examples
Merge PDF, Split PDF, Rotate PDF, Delete PDF pages, and JPG to PDF run locally. Compress PDF, PDF to JPG, and Remove PDF metadata use temporary server processing.
Privacy note
A browser-local label should only be used when files are not uploaded for processing. A server-processing label should explain retention, deletion, and validation.
Common mistakes
Do not assume all online tools work the same way. Do not claim a server-rendered workflow is without uploading. Do not ignore mobile browser memory limits for large local files.

FAQ
Which mode is more private?
Browser-local processing avoids upload for that workflow.
Why use server processing at all?
Compression, rendering, and metadata cleanup are more reliable with server-side PDF utilities.
Are server files permanent?
No. Server files are temporary and have cleanup and delete-now controls.
