Common questions
My image is still being rejected by the portal after compression.
Check the portal's official notification for the exact KB limit and dimensions. If the portal requires specific pixel dimensions (e.g., 200×230px), you may need to resize the image first. This tool handles file size only, not dimensions.
Does this tool work on mobile?
Yes. KBCompress works on any device with a modern browser: Android, iOS, desktop. No app installation required.
Can I compress multiple images at once?
Currently, one image at a time. Batch compression is on the roadmap.
