How to get a photo under 50 KB without losing quality
50 KB is the most common limit for photos on online application forms — big enough for a clear face, small enough for slow connections. Photos straight from a phone camera are 2–5 MB, so they need to be compressed about 50 to 100 times.
This tool does it in the gentlest way: it first lowers the JPG quality, and only if that isn't enough it reduces the width and height, then raises the quality again as high as 50 KB allows. A 50 KB photo is usually around 800–1500 pixels wide — sharp on any screen.
Photo still rejected? Check the form's other rules: JPG format, the exact size in pixels or cm, the DPI and sometimes a minimum size like 20 KB. Set them under Dimensions → Exact size. For signatures try compress to 20KB; for documents, compress to 100KB.
