LazPaint Download Formats: Installer vs Archive vs Portable vs AppImage

LazPaint 7.3 is distributed in several formats, and the right one depends on whether you want a system-wide install, a no-install folder you can run anywhere, or a single self-contained file. In short: Setup/installer installs LazPaint into your system; archive (no install) is a zipped build you unpack and run directly; Portable is a Windows build meant to run without installation; Deb package integrates with Debian-based Linux systems; and AppImage is a single-file Linux build that runs without installation.

The download page lists builds by operating system — Windows, Linux, Linux (Qt5), Linux ARM, UNIX, and MacOS — so the first step is matching the format to your OS and to how much system integration you want.

Installer vs. no-install archive

These two options exist for the same operating systems but behave differently:

On Windows, the Setup covers both 32-bit and 64-bit in one download. The archives are split: there is a separate 32-bit archive and 64-bit archive, each with no install.

On Linux, the same split applies: 32-bit and 64-bit Deb packages for installation, and 32-bit and 64-bit archives for running without installing.

The practical difference is system integration versus portability. An installer typically registers the app with your OS, while an extracted archive just gives you files you launch yourself — and you can delete the folder to "uninstall" it.

Portable (Windows)

Portable is listed only under Windows, as "Portable (32-bit and 64-bit)." It is a single download covering both architectures and is intended for running LazPaint without installing it — useful on a USB drive or a machine where you can't install software. If you just want a no-install Windows build and don't care about the 32/64-bit split, Portable is the simpler choice than picking an archive.

Deb package vs. archive (Linux)

For Linux, the page offers both Deb packages and archives:

• Deb package (32-bit / 64-bit) — for Debian-based distributions, installed through your package system.
• Archive (no install) (32-bit / 64-bit) — extracted and run directly, no package manager involved.

Choose the Deb package if your distribution uses .deb packages and you want LazPaint managed like other installed software. Choose the archive if you're on a non-Debian system, want to avoid installing, or prefer to keep the app self-contained in one folder.

AppImage (Linux)

AppImage 64-bit is listed as a separate Linux option. An AppImage is a single executable file that runs without installation, which makes it a good fit when you want one portable file rather than a folder of extracted files or a system package. It is listed for 64-bit Linux only.

Linux (Qt5) and Linux ARM

Two additional Linux categories exist:

• Linux (Qt5) — Qt5 variants of the same Deb package and archive options (32-bit and 64-bit for each). Use these if you specifically need the Qt5 build rather than the default Linux build.
• Linux ARM — 32-bit and 64-bit archives, no install. These are for ARM-based devices, where the standard x86 Linux builds won't run.

UNIX and MacOS

• UNIX — FreeBSD 64-bit archive (no install) and OpenBSD 64-bit archive (no install). Both are no-install archives.
• MacOS — a MacOS 64-bit download and a MacOS brew option, for installing via Homebrew.

Quick decision guide

• Windows, want it installed: Windows Setup.
• Windows, no install: Portable, or the 32-bit/64-bit archive if you need a specific architecture.
• Debian-based Linux, installed: Deb package (32-bit or 64-bit).
• Linux, no install, one file: AppImage 64-bit.
• Linux, no install, folder: archive (32-bit or 64-bit).
• ARM Linux device: Linux ARM archive (32-bit or 64-bit).
• FreeBSD/OpenBSD: the matching 64-bit UNIX archive.
• macOS: the MacOS 64-bit download or brew.

One thing the page does not state is pricing or any login requirement for these downloads, so treat availability and any conditions as things to confirm on the page itself rather than assuming they are unrestricted.
