Resize Image to Target Size (KB)
Compress Image to Custom KB – Set Your Own Target Size Online
Not all users want fixed file size targets. Sometimes, you need a photo that’s exactly 123KB or under 300KB — especially when working with resumes, PDFs, online forms, or custom CMS uploads.
Our Compress to Custom KB tool gives you full control. Simply enter the size you want in KB, and the tool compresses the image as close to that value as possible.
Why Use a Custom KB Compression Tool?
- Upload sites with exact file size caps (e.g., 99.5KB max)
- Compress for email attachments with tight limits
- Reduce image size before combining into a PDF
- Make all images in a set uniform in size
- Upload product images with max-size rules
Features:
✅ Input any target size in KB
✅ Smart image scaling + quality adjustment
✅ Compress JPG, PNG, WebP, SVG, BMP, and more
✅ Works 100% offline in your browser
