The most straightforward way to convert SVG files to PNG is using ImageMagick or Inkscape. Both are widely available in standard repositories and handle the conversion reliably. Using ImageMagick (convert/magick) ImageMagick provides the magick command (the modern equivalent to the older convert utility): magick input.svg output.png For basic conversions, that’s all you need. To control…
There are several tools available for extracting images from PDFs on Linux, each with different strengths depending on your use case and the PDF structure. pdfimages (Poppler Utils) The most straightforward approach is using pdfimages from the poppler-utils package: pdfimages document.pdf image This extracts all images and saves them as image-000.ppm, image-001.ppm, etc. By default,…
XSANE is a graphical scanner interface for Linux that provides straightforward scanning capabilities. When you scan documents or images, the JPEG output files can be surprisingly large depending on your settings. Here are practical methods to reduce the file size. Adjust JPEG Quality in XSANE The most direct approach is to lower the JPEG quality…
Finding quality free images for your website means balancing availability, licensing, and actual usability. While generic image search works, specialized repositories are faster and legally safer. Google Image Search (with license filtering) Google Images remains useful for locating free content, but the licensing filter is critical. Use the Advanced Search and filter by usage rights…
When submitting images to publishers or print shops, you’ll often need CMYK color space instead of RGB. The conversion is straightforward on Linux using ImageMagick’s convert command. Basic conversion The simplest approach uses the -colorspace option: convert from.tif -colorspace CMYK to.tif This works, but CMYK TIFF files can be quite large. Add compression to keep…

PowerPoint exports slides at 96 DPI by default, which is too low for professional printing. Print shops typically require 150 DPI for acceptable quality or 300 DPI for high-quality output. The UI export options in PowerPoint don’t reliably control the actual output DPI—you need to change a registry setting on Windows or use alternative methods…
MPlayer reached end-of-life years ago. Its active fork, mpv, maintains all screenshot functionality with identical or simpler syntax. This guide covers mpv, which handles both single captures and burst sequences. Enable Screenshot Support Screenshot support is built into mpv by default — no filter loading required. However, you can customize behavior by adding configuration to…
MPlayer and mencoder are obsolete. FFmpeg and mpv (the actively maintained fork of MPlayer) are the standard tools for video manipulation on Linux systems today. While some MPlayer syntax still works in mpv, FFmpeg is more performant, better documented, and handles modern codecs reliably. This guide covers practical tasks using FFmpeg and mpv, with mpv…
