How to Compress Sensitive PDFs Without Uploading Them
Contracts, scans, statements and internal reports can contain information that should not be sent to an unknown processing server. Local PDF compression keeps the document on your device while reducing image-heavy pages.

What upload-based compression means
A conventional online compressor transfers the complete PDF to remote infrastructure, processes it and returns another file. Even when a provider promises deletion, the workflow still requires disclosure to that provider and may create temporary copies, logs or backups.
How browser-based PDF compression differs
BrowserCompress downloads the application code, then reads and processes the selected PDF locally. File contents and filenames are not included in analytics requests. You can inspect the browser Network panel while processing to confirm there is no document upload.
Understand the output limitation
The PDF compressor renders pages as images to achieve meaningful reductions for scans and visual reports. The result looks similar on screen, but text will no longer be selectable or searchable. Keep the original and use this method only when that tradeoff is acceptable.
A safer compression checklist
Confirm you have authority to process the document, retain an original backup, select a suitable resolution and quality, review every page after compression, and remove the downloaded copy from shared devices when finished.
