Deep Dive: Image Compressor - Reduce Size
Shrink image file sizes by up to 95% without compromising visual fidelity. I engineered this tool to perform high-performance quantization directly within your browser. By utilizing the V8 engine and hardware-accelerated Canvas APIs, FileMint strips unnecessary metadata (EXIF/GPS) and optimizes the underlying pixel buffer stream.

Quick Start Guide
Select those chunky photos from your gallery or desktop and drag them right into the tool. You can even drop a whole batch at once.
Adjust the quality slider. I usually set it around 75% or 80%. It gets the file size way down while keeping the photo looking crisp. Go lower if you’re really desperate for space.
Watch the "Saved Space" counter update as you move the slider. It’s pretty satisfying to see that you’ve "saved 6MB" in like 2 seconds.
If you want to convert while you compress, you can switch from PNG to a slim JPG right here. It’s a double win for space saving.
Hit "Download All" and get your new, slimmed-down images in a neat package. You’re ready to upload without the "File too large" errors.

Technical Architecture
Canvas Quantization
We use the HTML5 `canvas.toBlob()` method with a variable encoder quality. This performs a sophisticated quantization process on the pixel data, reducing the bit-depth of less important colors to save significant space.
EXIF Stripping
When we redraw your image on the canvas, all the "invisible" data like GPS coordinates, camera model, and timestamps are naturally left behind, which is a great side-benefit for your digital privacy.
Browser-Native Encoding
By using the browser’s built-in encoders, we get hardware-accelerated performance that is far faster and more efficient than any cloud-based API could ever be for small to medium sets.
