Converseen vs GrabzIt

Converseen is a free batch image processor for Windows, Linux, macOS, FreeBSD and other operating systems. It converts, resizes, rotates, flips and compresses images, and renames groups using progressive numbers or prefix and suffix values. Through ImageMagick, it handles more than 100 formats, including DPX, EXR, GIF, JPEG, JPEG-2000, PNG, SVG, TIFF, WebP and HEIC/HEIF. It can turn a full PDF or selected pages into images with chosen dimensions and formats, and extract images from Windows icon files. Converseen is built with open-source frameworks and libraries including Qt and ImageMagick; its source is released under GNU GPL version 3. Linux installation options include source code, AppImage, Snap, Flatpak and distribution repositories. The program does not transfer information to other networked systems. The Free plan is free. Windows and Linux users need Ghostscript configured for PDF processing, and the macOS release is beta and not currently codesigned.

GrabzIt brings web capture, scraping, monitoring, and conversion tools together through APIs, online tools, and browser extensions. Its Web Capture API turns URLs or HTML into PDFs, DOCX files, screenshots, videos, animated GIFs, tables, icons, or rendered HTML. A cloud-based scraper uses a no-code wizard to extract structured data from static and JavaScript-driven sites, including pages behind logins. Results can be exported as Excel, XML, CSV, JSON, HTML, or SQL, or delivered through Dropbox, FTP, a database, a webhook, or email. Web Monitor tracks pages or selected sections and can alert users through email, Slack, or webhook when something changes. GrabzIt lists plugins for WordPress, Drupal, and Joomla, plus Chrome, Firefox, and Edge extensions. The product runs on Android, iOS, Linux, macOS, Windows, the web, and self-hosted setups. Its free plan costs nothing and includes basic features, a monthly scraping allowance, and monitoring for up to 50 webpage changes per month.
