The Most Private Way to Compress Images Online
Compressing photos should not require sacrificing your privacy. FileFit brings enterprise-grade image optimization directly to your local browser. No cloud servers, no data collection, just lightning-fast compression.
Why Client-Side Compression?
Traditional online image compressors force you to upload your files to their servers. This uses your internet bandwidth, wastes time waiting for uploads and downloads, and most importantly, puts your personal photos at risk of being stored or leaked.
FileFit flips this model upside down. We download the compression engine to your browser. Your images never leave your device.
Lossless vs. Lossy
Our tool uses intelligent lossy compression for JPEG and WebP files. This means it removes microscopic color details that the human eye cannot perceive, drastically reducing the file size (often by 70% or more) without making the image look blurry or pixelated.
For PNG files with transparency, we apply optimized compression to reduce the color palette while maintaining sharp edges.
Frequently Asked Questions
How do I reduce my photo size to exactly 50KB or 100KB?
Simply use the "Target Size" slider in the workspace above. Our engine will use a dynamic binary search algorithm to iterate through different quality settings until it finds the exact compression ratio needed to hit your target file size perfectly.
What file formats are supported?
We currently support full client-side compression for JPG, JPEG, PNG, and WebP images. You can also upload a PDF to extract and compress its internal images!
Is there a file size limit for uploads?
Because everything happens in your browser's memory, the only limit is your device's RAM. Most modern laptops and phones can easily handle compressing images up to 50MB directly in the browser without crashing.
