Guides & tutorials
Practical guides on JSON, images, PDFs and developer productivity, written by Wahaj Ansari, Founder & Editor.
How to Split a PDF by Chapters or Sections
Splitting a PDF by chapter is a page-range problem, not a guessing game. Learn how to find each chapter start, handle the front-matter page offset, build exact ranges, and name the output files so the chapters stay findable.
PNG vs JPG vs WebP for Social Media Uploads
Every social platform recompresses your image after you upload it. Learn which format survives that second compression best, the exact pixel sizes for Instagram, Facebook, X, and LinkedIn, and the simple export workflow that keeps photos sharp and graphics readable.
How to Reduce PDF File Size Without Losing Quality
A PDF that is too large to email is usually large for one reason: the images inside it. Learn how to tell whether your file is a text PDF or a scanned PDF, what DPI actually does to file size, and the exact workflow that shrinks a file without turning its text blurry.
