Compress under 100KB, without the upload step
Application forms and profile uploads sometimes have a strict 100KB limit. This tool makes a local JPEG copy and reduces quality or dimensions to approach that limit. The source remains untouched, and the result card displays the measured output size so you can verify it before uploading the copy to another service.
Small, simple images generally compress more easily than detailed photographs. The tool cannot promise that every image will fit while retaining acceptable quality. If a result is still above the limit, use a smaller source image or a lower quality setting and compare the preview.
The browser performs the work on your device, without a remote upload or account. Once you download the result, check the exact file size and any destination requirements such as dimensions, file type, or background color. Keeping a separate original is recommended whenever the image may be reused at full resolution.
Files are decoded and processed on your device. They are not uploaded to an ImageKit server, and the original files are never overwritten.

Frequently asked questions
Will every image be under 100KB?
Not always. Very detailed images may need stronger resizing or a lower-quality setting; verify the measured output.
Does the tool keep the original?
The original file is not changed. The processed result is a separate download.
Is processing private?
Your image stays in this browser tab. Processing runs locally on your device; the image file is not sent to an ImageKit server.
