Image Compressor: Shrink File Size Without Losing Quality
Whether you're hitting an upload limit, speeding up a website, or just tired of photos eating up storage, ConvertBrio's image compressor reduces file size while keeping images visually sharp. You control the quality level directly, so you can find the exact balance between file size and clarity for your use case — including a target-size mode for forms that demand an exact maximum.
How Image Compression Works
Upload your image and adjust the quality slider — lower values produce smaller files with more visible compression, higher values keep more detail at a larger size. ConvertBrio re-encodes the image at your chosen setting and shows you the result immediately, so you can compare before downloading.
Reducing an Image to a Specific Size (Like 100 KB)
Many government forms, job applications, and ID upload systems cap file size at a specific limit, often 100 KB. ConvertBrio's compressor can target that exact ceiling, adjusting quality and, if necessary, dimensions until the output fits — sparing you the trial-and-error of manually guessing a quality percentage.
How Much Can You Compress Without Noticing?
Most photos can lose 40-60% of their file size before the difference becomes visible to the naked eye, since JPG and WEBP compression is tuned to discard detail the eye is least sensitive to first. Start near the top of the quality range and lower it gradually while checking the preview, rather than guessing a low number up front.
Privacy and Batch Compression
Every upload is encrypted in transit and automatically deleted from ConvertBrio's servers within 24 hours. Free use covers one image at a time up to 25 MB; paid plans add batch compression for anyone processing large photo libraries or galleries at once.

Compress Image FAQ
Common questions about compressing and reducing image file size.
How do I reduce an image to under 100 KB?
Upload the image to ConvertBrio's compressor and set your target size to 100 KB. The tool adjusts quality — and dimensions if needed — until the file fits that limit, which is ideal for forms and ID uploads with strict size caps.
Will compressing my image make it look worse?
At moderate compression levels, most people can't tell the difference. Quality loss becomes noticeable only at more aggressive settings, so it's worth checking the preview as you adjust the slider rather than compressing to the smallest possible size by default.
Can I compress multiple images at once?
Compressing one image at a time is free with no account required. Batch compression for many images in a single pass is available on ConvertBrio's paid plans.
