Step 1: Check the size and format
The tool above is preselected to 450 KB. Choose one JPEG, PNG or WebP image from your device. If a service specifies JPG or another supported type, use the Output format control to match it.
Private exact-size compression
Use this page to make an image fit under, below, less than, up to or maximum 450 KB. It is useful for document uploads, profile images and email attachments when you need a specific target size without sending the image to a server.
Private image compressor
Choose one image, set the limit, and download a verified result. Your original is never changed.
Use this only when a form requires your image to be between two file sizes.
Resize image
Enter a width, a height, or both. No crop or fill is applied in this step.
Choose an image to preview planned dimensions.
Aspect ratio is off. Exact width and height may distort the image.

Instructions for this target
A promotional event image with a short headline may work inside a 450 KB publishing budget, subject to the text remaining clear.
The tool above is preselected to 450 KB. Choose one JPEG, PNG or WebP image from your device. If a service specifies JPG or another supported type, use the Output format control to match it.
Preserve sufficient dimensions for the intended display. If letters become blurry, a sharper original or different format helps more than another compression pass.
If you enter a width or height, use Resize and compress and keep Keep aspect ratio checked to avoid stretching. Resize only does not enforce a file-size limit.
Select the compress button, inspect the before-and-after previews and check the output size and dimensions. Download only after the size verifies below 450 KB and the image still looks suitable.
A file-size pass does not mean it meets every third-party image requirement.
The use case above illustrates what someone might do with a 450 KB budget. It is not a claim that any named organisation requires this exact limit. Check your receiving service's published maximum, accepted format and required dimensions.
Nearby exact sizes
Medium KB targets often balance acceptable visual quality with common upload limits. The workbench keeps the selected target editable if you need a nearby exact size.
