What This Project Does

PixelShift converts images between formats in bulk, directly on your machine. No internet connection required. No upload. No account. You select your files, pick an output format, and convert. Everything happens locally.

It also strips GPS coordinates and metadata from every file before saving - Privacy Mode is on by default. Every iPhone photo contains your exact location. PixelShift removes it before the file leaves your machine.

See It in Action

Watch how PixelShift converts a batch of iPhone HEIC photos, strips the GPS metadata, and saves everything to a folder - in seconds.

Who Uses It

The iPhone User

You took 100 photos but cannot share them because they are in HEIC format. Drop them in, hit JPEG, done.

The Privacy-Conscious Parent

You want to post a photo of your kids but do not want the hidden GPS coordinates to reveal your location. Privacy Mode removes it.

The Office Worker

Your company asked you to convert employee photos. Using an online converter uploads private files to a random server. PixelShift is fully offline - GDPR compliant.

The Website Builder

You have 50 high-quality photos that are 10MB each, too large to upload. Use the Resize tool to shrink all 50 at once.

How We Will Work Together

  1. Discovery - You tell me your workflow and what you need. I assess the scope and give you an honest estimate. No commitment needed.
  2. Scope - I send you a written scope: what gets built, what gets tested, when it ships, and what it costs. You approve it or we adjust.
  3. Build - I adapt PixelShift to your specific needs. You get progress updates every 2 to 3 days.
  4. Handoff - You test the tool. I fix anything that does not work. Final payment on delivery. Seven days of support included.
  5. You run it independently - The tool is yours. You have the code and the documentation. No dependency on me to keep it running.
