What to expect at this size
These are measured figures, not estimates. Five photographs were run through this page's own engine and the results written down.
The range is what varies between an easy photograph and a hard one: a flower against a blurred background compresses far better than a street full of signage.

Why do forms ask for this size?
Choose 500 KB when you want a smaller attachment or your destination names this limit. For several attachments, check their combined size.
For a web page, also match the image dimensions to its display size; a file size target alone does not determine loading performance.
What is the difference between resizing and compression?
The main difference between resizing and compression is the measurement you change. Resizing changes width and height in pixels. Compression reduces file size in bytes.
A photo can have the correct dimensions and still exceed an upload limit, so check both requirements.
If you need both, set the dimensions first and then adjust quality or the file size target. Work from the original and download once to avoid repeatedly recompressing a saved JPEG.
What happens to your photo?
Your selected photo is processed in your browser, without an image upload to a server. The page may download code and codecs needed for editing.
Save your result before closing the tab; unsaved edits are kept in memory rather than in an online account.
Common questions
Is 500 KB small enough to email?
A 500 KB photo is a relatively small attachment, but the limit applies to the whole message and depends on the provider.
Check the combined size when sending several photos, and use a smaller target if your message is rejected.
Can I keep the original dimensions at 500 KB?
The tool keeps your chosen dimensions while searching quality. Whether that reaches 500 KB depends on the image.
If the result remains over the target, reduce the width only as far as your destination’s requirements allow.
