v1.2.0-beta.1
Handle PDF and image conversion from a desktop app when internet access is unreliable or uploading files is off the table.
Use Orenvo PDF when the friction is not the PDF task itself, but the website you would normally have to trust.
Convert PDFs locally
Offline
Convert supported formats without an internet round-trip.
Avoid browser queues
Skip the upload/download loop that slows down urgent document tasks.
Keep control
Work from local folders and save the result where it belongs.
Why this workflow
Online converters are fragile in exactly the places people need documents done: travel, office networks, locked-down environments, or slow connections. Orenvo PDF gives the everyday merge, compress, and image conversion tools a local home.
Problem fit
For private paperwork, unreliable internet, or ad-heavy browser tools, Orenvo PDF gives the everyday PDF workflow a desktop path first.

Add files from local folders and set the output.
Process the job from the desktop app, even when the connection is unavailable.

Why Orenvo PDF
Merge, compress, and convert inside one desktop app
Work through local folders instead of web forms

Privacy and control
The workflow is intentionally direct: open local input, choose the needed settings, and save local output. That matters when a network connection is unavailable or inappropriate for the document.
Supported merge, compression, and conversion jobs run inside the installed app.
No account is required on Windows, macOS, or Android.
There are no per-tool limits, and exports have no watermarks.
FAQ
After installation, supported merge, compression, and conversion jobs can run without a connection on Windows, macOS, or Android.
It fits field laptops, locked-down office networks, travel days, private paperwork, or any workflow where a browser tab should not decide whether the job gets done.
