Quick answer: To compress an image to 500 KB, add it here, keep the 500 KB target and download the result. Images are limited to 1920 pixels on the longest side and saved at the highest quality under 500 KB, which keeps typical photos looking like the original on screen. The images never leave your device.
At 500 KB a photo can stay large and detailed. Add your images and each one is saved in Full HD at the highest quality that fits, with no fiddling with sliders.

Full HD at a high quality
With 500 KB to spend, this page limits photos to 1920 pixels on the longest side (Full HD) and then searches for the highest quality that fits. For most photos that leaves a quality setting where the compression is hard to spot on screen.
Want more pixels for a large or high-resolution screen? Set Maximum width or height to 2560 pixels. The file still ends up under 500 KB, at a somewhat lower quality.
Photos for websites and portfolios
| Use | Suggested size | Target |
|---|---|---|
| Full-width banner or hero image | 2560 px wide | 300 to 500 KB |
| Photo inside an article | 1200 to 1600 px wide | 150 to 300 KB |
| Portfolio or gallery image | 2000 to 2560 px | about 500 KB |
These are sensible starting points, not rules. Large images slow a page down more than anything else, so it is worth checking. For photos inside articles, compress to 200 KB is usually enough. WebP gives the smallest files and works in all current browsers; choose it under Save as.
Upload forms with a 500 KB limit
Some application and profile forms allow photos or scans up to 500 KB. Check whether the form also needs JPG or a set width and height; set Save as to JPG, and use Resize image first for exact dimensions. iPhone HEIC photos can be turned into JPG with HEIC to JPG. Your photos are processed in your browser and never uploaded.
