About the Image Compressor
A maximum file size is a ceiling, not an exact output size. This compressor first adjusts JPEG quality, then optionally reduces pixel dimensions while keeping the aspect ratio. It measures the downloaded Blob, not an estimate from a Base64 string. Fixed dimensions can prevent a target from being reached; the result reports that limitation instead of promising acceptance by a form.
Why Use This Tool
Frequently Asked Questions
Yes. Enable Maximum file size and select a preset. The result is checked against that maximum; difficult images may need smaller dimensions. A clear message appears if the bounded compression attempts cannot meet it.
