Guides and comparisons
How to get more out of the tools you already have.
How to Generate Bulk QR Codes from an Excel or CSV File
Generating one QR code is easy. Generating four thousand, each carrying different data and saved under its own file name, is a different problem — and most online tools either charge for it or ask you to upload the spreadsheet first. Here is how to do it locally on Windows, and what to get right before you start a run you cannot undo.
Batch Convert Images on Windows: HEIC, WEBP, AVIF and PDF Without Uploading
Online converters cap your batch, make you upload every file, and handle one job at a time. Here is how to convert, resize, compress, watermark and strip metadata from a whole folder of images on Windows — locally, in one pass, with no limit on how many files you throw at it.
How to Merge Hundreds of Excel and CSV Files Into One Clean Workbook
Copy-pasting forty spreadsheets into one file is not merging — it is hoping. Here is what actually goes wrong when you combine Excel and CSV files by hand, and how to do it properly in one pass: header mismatches caught and reported, duplicates removed across files, text numbers converted, and every row tagged with the file it came from.
Common questions
Are these applications really free?
Yes. There is no trial, no paid tier and no account. Each application is
published under an open-source licence and the source is on GitHub, so you can read it or build it yourself.
Do I have to install anything?
Most tools are a single portable
.exe. Download it, double-click it,
and delete it when you are done. Nothing is written to the registry.Why does Windows SmartScreen warn me?
SmartScreen flags any executable it has not seen often, including
unsigned open-source builds. Every release is scanned before publishing and the SHA-256
checksum is listed on the download page so you can verify the file you received.
Do the apps send anything over the internet?
No. The applications process files locally and make no network calls.
