About this tool
Exam forms, job portals and government sites often cap uploads at a size such as 50 KB or 200 KB. This tool lowers the quality step by step, and shrinks the dimensions if needed, until the file fits just under your target.
Output is JPG or WEBP because these formats can be compressed to a chosen size. Transparent areas of a PNG become white. If you only need smaller dimensions, use the bulk image resizer. If an app rejects a WEBP picture, convert it with the WEBP to JPG and PNG converter.
Frequently asked questions
How do I reduce an image to 50 KB?
Add your image, tap 50 KB, click Reduce size and download the result.
Will the quality drop?
Slightly. The tool keeps the highest quality that still fits your target, so a larger target gives a better picture.
Why is the result a little under my target?
The tool picks the best quality that stays below the limit, so the final size is close to the target but never above it.
Are my pictures uploaded?
No. Everything is processed in your browser and your files never leave your device.
