How it works
The compressor starts with a 250 KB target and attempts to export the selected image with smaller file size while keeping a usable visual result.
This target is useful for strict form uploads, small web thumbnails and situations where mobile bandwidth matters.
Privacy
ResizeKit does not send the selected file to a server. The browser handles preview, compression and download locally.
Limitations
A detailed photo may need resizing before it can fit under 250 KB. PNG output may remain larger because PNG is not quality-compressed like WebP or JPG.
Compress under 250KB FAQ
Why does my image stay above 250KB?
The original dimensions, detail and format may be too large for compression alone.
Can I keep transparency?
PNG and WebP can preserve transparency, but WebP is usually smaller.
Does ResizeKit store my image?
No. It uses temporary browser memory and does not store uploaded files.
