Compress Image to 300KB online
Use this free tool to reduce an image file size to around 300KB for online forms, applications, exam portals, profile uploads, and document submissions.
How to use this tool
- Select or drop your image in the upload box.
- Choose the required KB size, width, height, and output format.
- Click process and download the ready-to-upload result.
Why this helps
Many portals reject images because the file size, format, or dimensions do not match their upload rules. This tool gives clear before-and-after details so you can check the final file before submitting it.
Privacy note
The image tool runs in your browser where supported. That keeps the workflow fast and avoids unnecessary server uploads for normal image processing.
