How do I reduce a photo to exactly 500KB?
Add it above and tap Process all — the target is preset to 488 KB. The tool lands as close under the limit as it can at the best possible quality; hitting an exact byte count isn't needed, since upload forms only check the maximum.
Why is the target 488 KB and not 500 KB?
Some sites count 1KB as 1,000 bytes and others as 1,024. 488 KB (499,712 bytes) passes under either reading of 500KB. You can change the number in the settings panel if you know exactly how your site counts.
My photo still won't go under 500KB — what can I do?
Make sure the output format is JPEG or WebP: PNG is lossless and often can't reach small targets. For very small targets, also reduce the pixel dimensions under Resize. The tool already shrinks dimensions automatically as a last resort.
Will compressing to 500KB make my photo blurry?
Usually not at normal viewing sizes — the tool picks the highest quality that fits, and most photos look close to the original at this size.
Are my photos uploaded to a server?
No. Compression runs entirely in your browser — your photos never leave your device. See the Privacy Policy.
