About
How it helps
This image compressor is optimized for target-size workflows such as 20KB, 50KB, 100KB, and 200KB. It focuses on exact upload constraints used by application portals instead of generic percentage compression.
The tool runs entirely in your browser. Files are not uploaded to the server for the default flow, which reduces privacy risk and removes backend processing cost.
For high pass rates on strict limits, the engine uses both quality search and dimension downscaling. Quality-only compression often fails at very small targets like 20KB, so the resizing loop is essential.
Use the dedicated target pages for query-specific guidance such as signature workflows, range-based limits, and exam-form upload patterns.
FAQ
Frequently Asked Questions
+Does this tool upload my images to a server?
No. Compression runs locally in your browser for this workflow.
+Can I target exact sizes like 20KB or 50KB?
Yes. You can set a specific KB target and download the compressed result immediately.
+Why do some images still look blurry at very low KB?
Very strict limits require aggressive size reduction. Cropping and right-sized dimensions are critical to preserve readability.
