Compress Image to 500 KB
For email attachments, forum posts and messaging limits, 500 KB is the sweet spot — small enough to send, large enough to still look like a photograph.

How to compress an image to 500 KB
Add your image
Drag it in, browse for it, or paste a screenshot with Ctrl + V. Several files at once is fine.
Set the target
It is already set to 500 KB. Change it if your email provider or forum has its own limit.

Every file shows its before and after size. Save them one by one, or take them all as a single ZIP.
Why bother at 500 KB?
Half a megabyte is not a dramatic reduction, and that is the point: at this size most photos keep their full detail. You use it because something downstream refuses larger files — an email server with a 10 MB total attachment cap, a forum that rejects anything over 500 KB, or a messaging app that re-compresses badly and you would rather control it yourself.
Three photos at 4 MB each will bounce off a typical email limit. The same three at 500 KB go through, and the recipient sees no difference on a laptop screen.
Doing it well
- Compress, do not thrash. One pass from the original is right. Re-compressing an already-compressed file stacks the damage.
- Consider resizing instead. If the recipient will only view it on a screen, 1920 px wide is plenty — that alone often gets a 4 MB photo under 500 KB at higher quality than compression would. Try the Image Resizer.
- Never compress a photo you might print later. Keep the original; send the small copy.
