The privacy-first tool that runs entirely in your browser. No server uploads. Choose to organize files with smart renaming or keep original names intact.
Load this website, then turn off your internet/WiFi. You can still compress and rename unlimited images because everything happens locally on your device.
Designed for speed, security, and flexibility.
New! You are in control. Enable smart renaming to organize files by date, or disable it to keep your original filenames exactly as they are.
We don't need your data. The app runs locally using WebAssembly/JS. Feel free to disconnect your internet while using the tool.
If renaming is ON, we automatically detect 8-digit dates (YYYYMMDD) in filenames and format them perfectly in the new name.
Toggle renaming ON for organization, or OFF to keep originals.
Everything you need to know about PurePixel.
Yes. PurePixel uses browser-based technologies (WebAssembly and JavaScript) to process images directly on your device. Once the page is loaded, you can disconnect from the internet and it will continue to work perfectly.
You have full control. You can adjust the quality slider from 0-100%. Usually, a setting of 80% provides significant file size reduction with virtually no visible difference in quality.
PurePixel currently supports JPG, PNG, and WebP formats. It can compress these formats and even convert them to optimize for web usage.
Our algorithm looks for common date patterns (like YYYYMMDD) in your filenames. If found, it preserves them while organizing the rest of the name into a clean "IMG_Sequence_Date" format. If no date is found, it uses the current date.
