About the result
The chosen dimensions stay fixed. For JPEG and WebP, the tool reduces image quality to approach your file-size limit. PNG export keeps its lossless format, so its size may remain above the target. Results that miss the limit are clearly labelled. One KB means 1000 bytes.
Questions about this tool
Will it change my requested dimensions to meet the size limit?
No. Dimensions stay fixed. If quality adjustment cannot meet the limit, the tool tells you. You can then choose smaller dimensions or a different format.
How can I avoid cropping a signature?
Choose Fit whole image. It adds white padding when the image and requested output have different shapes.
