Help improve UNQIRO
Allow anonymous usage statistics? UNQIRO would count only which tool was used, whether it finished and which links between the tools and the Format Lab were followed. Your files, text and results are never included, and this use is not counted.
How the size is reached
The tool keeps the highest quality that fits 1 MB and reduces the dimensions only when it has to, without cropping. JPG, PNG and WebP keep their format. Any other size: Compress Image.
Frequently asked questions
Will the image be exactly 1 MB?
No, and it should not be. The file is 1 MB or less, as close to the limit as reasonably possible, so a form with that limit accepts it.
Why is my image smaller in pixels afterwards?
When a lower quality alone would leave visible blocks, the tool also reduces the dimensions, keeping the proportions. The result shows the new dimensions.
Can a PNG reach 1 MB?
PNG is lossless, so it only gets smaller with fewer pixels. If 1 MB would make it too small to be useful, the tool says so instead of making the file. A JPG or WebP of the same picture fits much more easily.
Will I see a difference after compressing to 1 MB?
Usually not on a normal screen: 1 MB leaves plenty of room for detail. Compare the preview of the result with your image before saving.
