Frequently Asked Questions
What is 100KB good for?
100KB images are ideal for web forms, profile pictures, email attachments, and any platform with strict file size limits.
Will the image look good at 100KB?
For photos under 2MP, yes. For larger images, some softness may be visible at 100KB. The quality slider lets you find the right balance.
Can any image be compressed to 100KB?
Most JPG and PNG images can reach 100KB. Very high resolution photos (20MP+) may need to be resized first for best results.
What formats are supported?
JPG, PNG, and WebP. SVG and GIF have different compression mechanisms.
Is the compression lossless?
No — to hit a specific file size target, lossy compression is used. The tool binary-searches for the optimal quality setting.
