What is PDFscaler?
PDFscaler is a free online toolkit for working with PDF files. It lets you merge PDF files, compress PDFs, split documents, and convert PDFs to Word, JPG, PowerPoint, and Excel. Tools also cover converting Word, PowerPoint, Excel, JPG, PNG, and HTML files to PDF, plus PDF editing features such as page numbers, watermarks, cropping, annotations, and form filling.
The site also includes image tools for cropping, resizing, compressing, blurring, merging, and removing backgrounds, along with a set of calculators and utilities such as EMI, SIP, age, BMI, word counter, password generator, QR code generator, and JSON formatter. It is aimed at anyone who needs quick document and image tasks without installing software.
The main difference, according to the page, is privacy. Files are processed inside the user's web browser and are said never to be sent to servers, with no account signup, no logging of file content, and no document caching. The tools are described as free with no watermarks or usage limits.

We decided basically to retreat to move forward — there are a lot of assumptions stacked here and we don't really know how many of these are true. Where's a simple place to start, and then proceed from there, meticulously brick by brick?
Retreat to move forward: simplify to a provable foundation before layering strategy
V1 Sports' switch to free trial was an epistemological reset as much as a monetisation change. Years of turnover had left the team running on unverified stacked assumptions. The decision to go back to basics — list only what you are certain is true and build deliberately from there — is a reproducible framework for any app that has accumulated strategy debt without a clear thesis it can still defend.
There's a play for whatever you're stuck on.
