Prevux icon Prevux 1.0 – with tabs, glass toolbar, slideshow and much more

Images and PDFs.
Just like on the Mac.

View, mark up, sign and fill in – as familiar as Preview on the Mac.
Now on Linux. Free, open source and entirely without internet.

Install for free All features
Prevux with three documents in tabs: a hiking guide as a PDF with the markup toolbar, highlighter, circle, arrow and label on a photo

A move.
Not a fresh start.

Prevux adopts the layout, tools, keyboard shortcuts and even the menu names of Preview – “File”, “Save”, “Crop”. If you come from the Mac, you will find everything where your hand looks for it. And if you have never used Preview, you simply get a calm, tidy program for images and PDFs.

Edit

Show
what matters.

Mark up, fill in, sign, adjust – without a second program.

Shapes, arrows, text.
And a loupe.

On photos as on PDFs. The loupe magnifies a spot and shows with a line where it comes from. Everything stays editable, even after saving.

Photo with circle, arrow, label and loupe

Sketches that
turn out nicely.

A wobbly circle becomes a clean circle, a shaky arrow a straight one. With a graphics tablet or pen, the line gets thicker the harder you press.

PDF with highlighter, circle and arrow

The page flows on
beneath the toolbar.

The toolbar is made of glass: as you scroll, the document shimmers softly through it. Zooming and scrolling glide smoothly to where your mouse pointer is. Prefer it plain? “Reduce transparency” in the settings.

Fill in. Sign.
Done.

Fields, checkboxes and pop-up lists right in the PDF, with Tab to the next field. You draw your signature – or photograph it on paper, and Prevux turns it into clean lines.

Filled-in form with signature

Many images.
One size.

Select several images and adjust them together: fit them to common sizes, in pixels, percent or centimetres – with or without resampling.

Sidebar

Always know
where you are.

Thumbnails, table of contents, bookmarks and search results – one click and you are on the right page.

Prevux sidebar

Several files open at once? The sidebar shows them all. Drag pages with the mouse to a new place – even from one PDF into another.

Features

And so much more.

The little things that make Preview so useful – rebuilt piece by piece.

Tabs

Many files in one window. Ctrl Tab moves on, and a tab can be dragged into a window of its own.

Bookmarks

Remember important pages with Ctrl D – they stay even after you close the file.

Slideshow

Show images and pages full screen – arrow keys to go on, Esc to go back.

Versions

Every save creates a version. “Revert To …” brings back an earlier state.

Adjust Size

One image or several at once: fit them to common sizes, in pixels, percent or centimetres.

Remove Background

One click and the subject stands free – to reuse as a PNG with transparency.

Scanner and camera

“Import from Scanner” – also over the network and with a document feeder straight to PDF. Or take a photo with the camera.

Colour profiles

Assign a profile and soft proof: see beforehand how your image will look on the printer.

Lock a file

Locked files cannot be changed by accident. Duplicate, rename and move right from the title.

Opens more than images and PDFs

Prevux opens Markdown, text files, HTML pages and e-books as neatly typeset documents – for reading, marking up and saving as PDF. The sidebar shows animated GIFs frame by frame.

Location

Shows where a photo was taken – and removes the location on request before you pass it on.

Privacy

Your documents
stay yours.

Contracts, ID cards, bank statements, doctors’ letters: what you open in a PDF program is often the most private thing of all. That is why nothing leaves your computer with Prevux.

Redacting means deleting

Redacted text, graphics and pixels are really removed from the PDF when saving – not just covered with a bar.

Live Text stays local

Text recognition in photos and scans runs on your computer. No image is uploaded anywhere.

This site too

No cookies, no third-party fonts or services, no access logs. The JavaScript on this site runs only in your browser and sends nothing.

Install

Get started. For free.

For Ubuntu and other Linux systems with GTK 4 and libadwaita 1.8 or later.

Ubuntu

Developed and tested on Ubuntu 26.04 LTS
Terminal
$ sudo apt install python3-gi gir1.2-gtk-4.0 gir1.2-adw-1 python3-venv git
$ git clone https://github.com/veritasX1/prevux.git
$ cd prevux
$ ./install.sh

Prevux then appears in the applications menu and under “Open With”. To have it open all PDFs and images from now on:

Terminal
$ xdg-mime default io.github.veritasx1.Prevux.desktop application/pdf image/png image/jpeg image/webp image/tiff image/gif image/bmp

Optional: tesseract-ocr for Live Text (English included), sane-utils for scanners.

Version 1.0. The interface is available in German, English and French; Russian is planned. Bugs or ideas? Welcome in the issue tracker.
