The tool above is preselected to 800 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.

Instructions for this target
How to compress an image below 800 KB
An event-poster graphic or product image may use an 800 KB internal publishing budget, allowing a little more detail.
Step 2: Adjust settings for 800 KB
Check small lettering and colour gradients after processing. This tool reduces bytes and can resize pixels; it cannot redesign poster text or correct layout mistakes.
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.
Step 3: Verify the download
Select the compress button, inspect the before-and-after previews and check the output size and dimensions. Download only after the size verifies below 800 KB and the image still looks suitable.
A file-size pass does not mean it meets every third-party image requirement.
About this example
The use case above illustrates what someone might do with a 800 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.

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.
