Compress Image to 300KB Online — Free

Reduce any image to under 300KB without an obvious drop in quality. A 300 kilobyte target suits larger, detailed photos that you still want to keep reasonably small for uploads and web pages.

Required photo dimensions and file sizes differ between forms and change over time. This tool helps you hit a common target, but always verify the exact requirement on the official form or notification before you submit.

How to compress to 300kb

  1. Drop your image in, or click to browse and select it.
  2. The tool automatically finds the highest quality that still fits under 300KB.
  3. Check the live preview and the final file size.
  4. Download your optimised image — ready to upload.

FAQ

Frequently asked questions

Very little for most images. 300KB is generous enough that the compressed photo is usually indistinguishable from the original on screen.

No. We never store, share or look at your images — every file is discarded the moment processing finishes and nothing is saved. That makes it safe even for sensitive documents like passports, ID cards and bank statements.

Yes. There is no cost, no watermark and no account needed. Anonymous users get a generous daily limit, which is plenty for everyday use.
