Compress image to 500 KB
Get any photo under 500 KB without guessing quality settings. Drop it in, and the tool finds the best version that fits, right on your device.
When you need 500 KB
- Online forms and LMS uploads with a 500 KB cap
- Full-width website banners
- Sharing photos in chat without the app recompressing them heavily
What to expect
500 KB leaves room for large, detailed photos. Many images from modern phones (often 2–5 MB) reach this with dimensions intact.
Questions
How do I compress a photo to 500 KB?
Add the image above; the target is already set to 500 KB. The tool finds the highest JPEG quality that fits under 512000 bytes, shrinking the width only if needed, then you save the file.
Why is my image under 500 KB but smaller than expected?
The search steps in quality increments and always stays under the limit, so the result is usually a little below the target. That leaves margin for forms that count KB as 1,000 bytes.
My form also requires exact pixel dimensions. What do I do?
Enter the required width and height as max width and max height before adding the image. The tool resizes first and then fits the size target, which gives better quality than letting it shrink on its own.
Is my photo uploaded?
No. The compression runs in your browser with WebAssembly; the file stays on your device. That matters for ID photos and signatures.
