The self-hosted, open-source PDF toolkit offered 50+ tools, consistent cross-device access via browser, no file uploads to third parties, and no premium gates. However, the full version's JVM-based Spring Boot architecture consumed significant memory — problematic on a resource-constrained 8-year-old laptop already running 20+ containers. The solution was switching to the ultra-lite version capped at 1GB RAM, sacrificing a few rarely-needed features. The takeaway: self-hosted doesn't mean lightweight, and the real cost of replacing commercial software is understanding the infrastructure trade-offs. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why does Stirling PDF use so much memory on my home server even when idle? The full Stirling PDF image (frooodle/s-pdf:latest, about 1.6GB) runs as a complete Spring Boot app server, so the JVM keeps everything resident in memory and its garbage collector does not release RAM back to the OS after a job. Underneath it bundles PDFBox, LibreOffice, Tesseract, and QPDF, making the app-server layer the source of overhead rather than the actual PDF processing. _For memory-tight homelabs, daily.dev surfaces real-world resource trade-offs before you commit hardware to a new self-hosted tool._ ### How can I reduce Stirling PDF's memory usage on a low-resource server? Switch to the ultra-lite version of Stirling PDF and cap its memory allocation, for example at 1024 MB via the compose file. This drops a few features but avoids the JVM heap behavior of the full Spring Boot app server, which keeps consuming memory it does not return to the OS after processing jobs. _Homelabbers tuning container memory limits can track practical fixes like this through daily.dev._ ## Similar posts on daily.dev - [I ditched Adobe Acrobat for a self-hosted PDF editor that uses less memory than my browser](https://daily.dev/posts/i-ditched-adobe-acrobat-for-a-self-hosted-pdf-editor-that-uses-less-memory-than-my-browser-5gyrtqjes) · XDA Developers · 0 upvotes · 0 comments - [I tried 2 Docker-based PDF editors to replace Adobe Acrobat, and only one stood out](https://daily.dev/posts/i-tried-2-docker-based-pdf-editors-to-replace-adobe-acrobat-and-only-one-stood-out-dmf2z2ihd) · XDA Developers · 1 upvotes · 0 comments - [I stopped trusting online PDF tools after finding out what one Docker container does offline](https://daily.dev/posts/i-stopped-trusting-online-pdf-tools-after-finding-out-what-one-docker-container-does-offline-xtpmd2411) · XDA Developers · 1 upvotes · 0 comments - [I don’t pay for Adobe Acrobat, Foxit PDF, or Nitro PDF, I use this free self-hosting tool to edit my PDFs](https://daily.dev/posts/i-don-t-pay-for-adobe-acrobat-foxit-pdf-or-nitro-pdf-i-use-this-free-self-hosting-tool-to-edit-my-lx1voazvr) · XDA Developers · 0 upvotes · 0 comments - [I stopped uploading PDFs to random websites after finding this free desktop app](https://daily.dev/posts/i-stopped-uploading-pdfs-to-random-websites-after-finding-this-free-desktop-app-nlg8h7pmt) · XDA Developers · 0 upvotes · 0 comments --- Tags: [#docker](https://daily.dev/tags/docker), [#self-hosting](https://daily.dev/tags/self-hosting), [#homelab](https://daily.dev/tags/homelab) [View this post on daily.dev](https://daily.dev/posts/i-replaced-adobe-acrobat-with-stirling-pdf-but-the-real-cost-wasn-t-what-i-expected-irt4utbhu) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"I replaced Adobe Acrobat with Stirling PDF, but the real cost wasn't what I expected","url":"https://daily.dev/posts/i-replaced-adobe-acrobat-with-stirling-pdf-but-the-real-cost-wasn-t-what-i-expected-irt4utbhu","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/i-replaced-adobe-acrobat-with-stirling-pdf-but-the-real-cost-wasn-t-what-i-expected-irt4utbhu"},"datePublished":"2026-08-02T10:03:30.673Z","dateModified":"2026-09-14T07:40:23.308Z","description":"A developer shares how they accidentally replaced Adobe Acrobat with Stirling PDF after installing it on a home server out of curiosity.
