• Exporting a print-ready A4 PNG and PDF entirely in the browser

  For the PDF we lazy-load pdf-lib only when someone asks for a PDF, so it never weighs on the first page load. The page is A4 in points (595.28 × 841.89), and the image fills it exactly. - Source: dev.to / 12 days ago

• API Workflow Automation Vercel: Connect Document Processing to Your Tech Stack

  Bundle size is the first. When you install a native PDF library, you're pulling in compiled binaries. Vercel's function bundle limit is 250 MB uncompressed. A library like pdf-lib stays small, but anything that links to a system binary (Ghostscript, poppler, native Tesseract) blows past that ceiling quickly and degrades cold-start times for every function in the deployment. - Source: dev.to / 17 days ago

• How I built a free PDF editor that keeps your fonts and never uploads your file

  This is the part most editors skip. With pdf-lib I decompress the page's content stream and walk it operator by operator, tracking where every piece of text lands:. - Source: dev.to / 25 days ago

• Merge PDFs in the browser with pdf-lib, and what it silently drops

  You can merge PDFs entirely in the browser with pdf-lib. No server, no upload, about ten lines. We use exactly this in a small tool, so here is the whole thing, plus the two things it silently drops, which I checked rather than assumed. - Source: dev.to / 27 days ago

• Resizing PDF pages with pdf-lib without losing links, bookmarks and form fields

  I build Filewhisk, a set of file tools that run entirely in the browser, and this week I added "resize PDF pages": change every page to A4, US Letter or any size. The obvious way to do that with pdf-lib takes about ten lines. It also quietly deletes every link and bookmark in the document. - Source: dev.to / 28 days ago

• Merging PDFs in the browser without uploading anything: what I learned building a free tool for Argentine paperwork

  Pdf-lib to create and modify PDFs (merge, split, rotate, images to PDF, remove pages). - Source: dev.to / about 1 month ago

• pdf-lib is silently deleting characters from your users' data

  I generate invoices in a Node serverless function with pdf-lib. It is a good library. It also quietly destroyed a client's company name, threw nothing, logged nothing, and produced a PDF that opened perfectly. - Source: dev.to / 2 months ago

• I Built a PDF Toolkit That Runs 100% in the Browser — No Server, No Uploads

  Pdfcevir does everything in the browser using pdf-lib and pdf.js. No file ever leaves your device. There's no backend processing the PDF — the JavaScript running in your tab does all the work. - Source: dev.to / 4 months ago

• How to Detect Tampered PDFs (Forensics Tutorial)

  I use pdf-lib for structural parsing. It handles the xref table and object access well. For raw binary analysis — finding byte offsets, scanning for marker strings — I work directly on the ArrayBuffer. - Source: dev.to / 6 months ago

• I shipped a website-to-PDF SaaS on WordPress — here's the stack

  PDF assembly: pdf-lib for multi-page PDFs (each page becomes its own PDF page). DOMPDF for single-page fallback. - Source: dev.to / 6 months ago

• I Built a Free Invoice Generator, Resume Builder, and Cover Letter Generator That Don't Require Signup

  With browser-based tools, the architecture makes privacy the default. There's no server to send data to. The pdf-lib library generates the PDF in a Web Worker, the browser creates a Blob URL, and the download happens through a local anchor click. Your data exists in browser memory until you close the tab. - Source: dev.to / 6 months ago

• pdf-lib Is an Under-Appreciated Gem: A Tiny PDF API in TypeScript

  The right abstraction is an HTTP service with four endpoints: /merge, /split, /rotate, /info. Small, boring, self-hosted, readable in an afternoon. I wrote one and called it pdf-merge-api. The punchline is that the entire thing is about 600 lines of TypeScript and zero native dependencies, because pdf-lib is an under-appreciated gem. - Source: dev.to / 7 months ago

• I Built a Free Browser-Based PDF Merger That Never Uploads Your Files

  If you're a developer who works with PDFs programmatically, pdf-lib is genuinely excellent. The docs are solid, it handles most PDF operations you'd need, and it runs in Node.js too if you need server-side processing. - Source: dev.to / 7 months ago

• Show HN: Printable Classics – Free printable classic books for hobby bookbinders

  Not yet and it's a little messy now to be honest. The pipeline itself is in node.js and uses mostly pdf-lib (https://pdf-lib.js.org/) and ebook-convert (https://manual.calibre-ebook.com/generated/en/ebook-convert.html) For epubs, I split the book into chapters and run ebook-convert on each chapter individually, adding an extra page if needed to make the number of pages even. Then I combine all the chapters and do... - Source: Hacker News / 9 months ago
