3

Best fit for

  • Accountants sending reports and client packets
  • Recruiters sharing resumes, offers, and handoff docs
  • Consultants or sales teams sending proposals by email

Start with medium compression

The current tool performs lossless structural optimization. A smaller output is not guaranteed, so compare the reported byte counts.

Compress the final file, not the draft stack

Merge or split first, then optimize the version you plan to send and retain the original when the result is not smaller.

Check size before you resend

Use the smallest readable copy when your recipient is getting the file by email, not through a document portal.

Understand the processing boundary

Supported workflows process document bytes in the browser without uploading them to LocalPDF for processing. This does not secure your device, browser extensions, downloads, storage, or later sharing.
