Compress Image to 100KB Online
Need to upload an image under 100KB for forms, applications, or websites? The fastest way is to resize dimensions first, then apply balanced compression. This keeps text and edges readable while reducing file size.
Start With The Right Dimensions
Most large files are oversized in pixel dimensions. For many uploads, reducing width to around 1000 to 1600 pixels before compression gives the best quality-to-size result.
Compress Gradually, Not Aggressively
Use medium quality first, then check output size. If the file is still above 100KB, lower quality in small steps.
This avoids obvious blur and block artifacts while helping you hit strict upload limits.
Verify Before Download
Always preview fine details like text, faces, and product edges before downloading.
If quality drops too much, increase quality slightly and reduce dimensions a bit more.
To apply these steps quickly, open the compressor at /compress-image and iterate in small adjustments.
