About Target Size Image Compression
This tool is designed for exact upload limits such as image under 50KB, 100KB, or 200KB. It works well for forms, exam portals, job sites, and profile-photo rules where file size matters more than using a single default quality setting. Compression happens in your browser so your images stay on your device. Whether you are optimizing for the NBN, preparing myGov submissions, or sharing files across Australia's vast distances, this tool keeps your files light and quick to transfer — even on regional, fixed-wireless, and satellite connections, with no upload required.

Frequently Asked Questions
Can I compress an image to exactly 100KB?
Often yes, especially for JPG and WebP files. If the exact target cannot be reached because of the original format, dimensions, or quality limits, the tool shows the closest best-effort result.
Which image formats are supported?
The tool supports common image formats including JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, and HEIC.
Should I allow format change?
Allowing format change can make it easier to hit smaller targets because formats like JPG or WebP are often more size-efficient than PNG. Keep the original format when you have strict format requirements.
Is this image size reducer private?
Yes. Image processing happens locally in your browser, so your files are not uploaded to a server.
