Why compress to an exact size?
Many platforms have strict file size limits: email attachments (25MB), web forms (2-10MB), social media uploads, and government portals. Our binary search algorithm automatically finds the optimal compression level to hit your target size — no manual trial and error needed.
How target size compression works
Our compressor uses a binary search algorithm to find the exact quality setting that hits your target file size. It iteratively compresses at different quality levels, measuring the output size each time, until it converges on your target — usually within 5-8 iterations. This is far more precise than guessing with a quality slider.
