Online Image Compressor

Most online image compressors give you an ambiguous quality slider and leave you guessing what the resulting file size will be. Our precision image compressor uses an automated binary search algorithm to hit your exact target in kilobytes (KB) or megabytes (MB) on the first try.

Frequently Asked Questions about Image Compression

How does exact KB file size compression work?
We use a hardware-accelerated binary search algorithm across canvas compression quality parameters directly in your browser. It continuously tests the resulting file size until it hits as close to your target as possible without exceeding it.
What if my image is too large to fit in the target KB?
If an image cannot fit within your target KB even at the lowest compression quality (0.05), our engine progressively scales down the dimensions in 10% steps until the exact file size threshold is satisfied.
Are images uploaded to any server?
Never. All compression takes place 100% locally on your computer or phone using modern HTML5 Web APIs.
Can I batch compress multiple photos to the same KB limit?
Yes! Drag multiple photos into the tool, set your desired KB target, and download individual files or all of them packaged inside a ZIP file.
