How to Merge, Split & Convert PDFs Without Uploading Files
OmniSave PDF Studio runs 100% inside your web browser using WebAssembly and PDF-Lib. Confidential contracts, invoices, bank statements, and university assignments never leave your device.
Select Merge PDFs, Images to PDF, or Extract / Split PDF from the top bar.
Drag and drop your PDFs or images, reorder them with the up/down arrows, or choose your page range.

Why Local Browser PDF Processing Beats Traditional Online PDF Sites
Most free PDF websites require you to upload sensitive tax forms, signed contracts, or ID scans to their remote cloud servers, and then lock basic features behind daily limits or expensive monthly subscriptions.
OmniSave PDF Studio processes your documents directly in your device's RAM. Merging a 50-page report or converting 20 receipt photos into an A4 PDF takes less than a second and uses zero upload bandwidth.
