When do you need a 500KB JPEG?
Many websites and online forms reject uploads above 500KB. This is common for blogs, online stores and high-quality web photos. Product photos, blog headers and portfolio images look crisp at 500 KB while still loading far faster than camera originals.
Our tool searches for the highest JPEG quality that still fits under 500KB, so you keep as much detail as possible. If the image is very large, it is also scaled down a little until it fits, and the new dimensions are shown under the image.
Frequently asked questions
Will there be visible quality loss at 500KB?
Usually not. Most phone photos fit under 500 KB at high quality settings without being resized.
Will the file be exactly 500KB?
It will be at or just under 500KB, never over. Upload portals only check the maximum, so a file slightly below the limit is accepted.
Are my photos uploaded to a server?
No. Compression runs entirely in your browser using WebAssembly. Your images never leave your device.
Can I compress PNG or WebP to this size?
Yes. PNG and WebP images are converted to JPG while compressing. Transparent areas become white.
