About This Tool
This page is designed for one of the most common real-world file tasks: reducing an image so it fits a strict upload limit without guessing over and over again. Instead of asking you to estimate quality settings manually, the tool targets the file size directly.
That makes it useful for official forms, university portals, exam websites, employment applications, and anywhere else that rejects files above a narrow KB limit. Upload the image, choose the target, and download a version sized for submission.
Why People Use It
- Preset targets like 20 KB, 30 KB, 50 KB, 100 KB, and 200 KB plus custom sizes
- Preview-driven workflow so you can verify the result before submitting it elsewhere
- No account, no watermark, and no long multi-step export flow
Typical Use Cases
- Fitting profile photos into job application limits
- Reducing image uploads for government or education forms
- Creating smaller copies for email attachments and chat sharing
- Preparing photos for websites that cap upload size aggressively

Common Questions
Can I resize an image to 20 KB, 50 KB, or 100 KB exactly?
Yes. The tool is built around target file size, not just width and height. You can use presets such as 20 KB, 30 KB, 50 KB, 100 KB, and 200 KB or enter a custom value.
Does the image keep the same dimensions?
The tool first tries quality adjustments and only reduces dimensions when needed to reach very small targets. That balance helps preserve readability while still fitting strict upload rules.
Are my uploaded images stored?
No. Files are processed only for the current request and are not kept as a permanent upload library.
