Image Compressor & File Size Resizer
Shrink a photo by quality, or tell it the file size you need (for example 50 KB) and it finds the best quality that fits. Optionally set exact pixel dimensions too.

Getting a photo to an exact size
In “Target file size” mode the tool tries many quality levels and keeps the highest quality that still fits under your limit. If even the lowest quality is too big, it shrinks the picture a little at a time until it fits. For exam forms, set the width and height your form asks for and a maximum such as 50 KB; use “Make the file at least” when the portal also demands a minimum. PNG is lossless, so its size can’t be controlled — use JPG or WebP for a size target.
About the Image Compressor & File Size Resizer
The Image Compressor shrinks a picture to an exact file size, such as under 50 KB or 200 KB, or by a quality setting. You can also set exact width and height. It is designed for forms and portals that limit upload size, and for making web pages lighter.
JPG and WebP are lossy formats, so lowering quality reduces file size at the expense of fine detail. In target size mode the tool tests many quality levels and keeps the highest one that fits your limit, and it reduces dimensions if even the lowest quality is too big. PNG is lossless, so its size cannot be controlled. Transparent areas are filled with a background colour you choose when you export to a format without transparency.
How to use it
- Upload the image.
- Choose to compress by target file size or by quality.
- Set the maximum size, output format and, if needed, width and height.
- Press Compress, check the preview and download.
Tips and good to know
- Choose JPG for photos and WebP for the smallest files.
- When you set both width and height, choose between fit inside, exact stretch, or crop to fill.
- Keep your original in case you need a larger version later.
