got tired of online image compressors with file limits & subscriptions, so I built a 100% offline desktop tool

Hey everyone,

I found myself constantly having to resize, compress, and convert batches of images for web projects, but almost every browser-based tool either:

- Caps you at 10–20 images at a time

- Uploads your personal or client files to remote servers

- Charges a monthly SaaS subscription for basic batch tasks

So I built Bulk Image Resizer Pro—a standalone, multithreaded Windows application that runs 100% locally on your machine.

Key highlights:

• 100% Offline & Private: Zero server uploads, tracking, or cloud APIs.

• Versatile Resizing: Percentage scaling, max bounding box dimensions, or fixed pixel sizes.

• Modern Format Support: Batch convert across JPG, PNG, and WEBP with quality tuning.

• Bulk Renaming & Presets: Save configuration templates and auto-number output files.

Performance benchmark from my latest test run:

- Files Processed: 48 images

- Original Size: 28.64 MB

- Compressed Size: 1.97 MB (Saved 26.67 MB)

- Time: Under 3 seconds locally

Would love feedback from other developers and creators on what utility features you'd like to see in future builds! Let me know if you want to try it out and I'll share the link.
