pdftotext -raw -eol dos corrupted.pdf output.txt Librarians and archivists use pdfimages (with -png ) to extract figures from scientific papers stored in a 32-bit NAS:

for f in *.pdf; do pdfimages -png "$f" "$f%.pdf"; done A headless Raspberry Pi 1 (32-bit ARM, but similar constraints) running an x86 emulator like QEMU-user can use pdftohtml to generate static HTML for intranet servers:

docker run -it --rm i386/debian:stretch bash apt update && apt install -y poppler-utils pdftotext -v # Should show poppler-0.68.0 (Debian 0.68.0-1) For the ultimate control and optimization, or when your distribution no longer supports 32-bit, compile from source. Prerequisites (x86 system or cross-compilation) Install build dependencies:

While it may not be the latest release, version 0.68.0 for the x86 (32-bit) architecture occupies a crucial niche. It represents a stable, feature-complete snapshot that continues to power legacy systems, embedded devices, and conservative enterprise environments. We will explore what Poppler is, the significance of this particular build, its core utilities, installation methods, compilation from source, and why the 32-bit x86 version still matters today. Poppler is a PDF rendering library based on the Xpdf-3.0 code base. Created by Kristian Høgsberg, its primary goal is to provide a lightweight, high-performance set of tools and APIs for extracting, manipulating, and displaying PDF content.
