Compressing Images to Under 50 KB
For 50 KB we convert each image to WebP around Q80 and resize large sources to about 1280 px. This is ideal for batch thumbnails, mobile images, and consistent small-size galleries across mixed formats. The auto-detection handles each input appropriately, applying format-specific settings behind the scenes. Quality stays good at thumbnail sizes. Use it when you need a folder of varied images to share one small, uniform size budget.

Frequently Asked Questions
How does it handle animated GIFs in a batch?
Animated inputs are converted to animated WebP to preserve motion while meeting the size budget, dropping frames only if necessary.
Can I keep each image in its original format?
Yes, choose original-format output, though WebP usually meets the 50 KB budget with better quality than re-compressing legacy formats.
