Compress an Image to 500KB
Compress to an upload limit
Choose the maximum file size accepted by your form or website.
Set a custom upload limit
Use the unit stated by your form. KB and MB here mean 1,000 and 1,000,000 bytes; the tool's Target size uses 1,024-byte KB.
This sets a compression target, not a guaranteed result size. Run compression, inspect the image, and check the downloaded file's actual bytes. Tight limits can reduce quality or dimensions.
Presets leave a small margin below the limit. Check the result size; a very small limit may require smaller image dimensions.
Supported extensions (expand/search)
Supports many aliases including jpeg.

How to compress an image for a 500KB upload limit
- Choose your image. Target size starts at 488 KB, equivalent to 499,712 bytes.
- Run compression and compare the output preview with the original. Check faces, text and sharp edges.
- Download the output, inspect its actual file size, and confirm the form accepts its format and dimensions.
For a passport, application or listing form with a 500KB maximum, the exact byte limit matters. Decimal 500 KB means 500,000 bytes; 500 KiB means 512,000 bytes. This page starts below the smaller limit.
A size target can reduce quality or dimensions. If the result still exceeds the limit, lower the target slightly or use Image Resize to match the dimensions requested by your form, then compress again from the original. Use Image Compressor for a different size or quality target.
Why is the target 488 KB instead of 500 KB?
A form that uses decimal KB accepts up to 500,000 bytes. The compressor uses 1,024-byte KB, so 488 KB is 499,712 bytes. If your form explicitly permits 500 KiB, you can set 500 instead.
Will every image finish below 500KB?
The setting is a target. Check the downloaded file’s actual byte size and the form’s requirements. A detailed or large image can require a lower target, smaller dimensions, or a different output format.
How do I keep small text readable?
Preview the result at full size before uploading it. If text or edges become unclear, start again from the original and resize to the dimensions required by the form. Keep the original file.
