How to compress image to 500kb
- 1Upload the image you want to make smaller.
- 2Set your target file size — 500KB is the default.
- 3The tool automatically lowers the quality until the file fits under your target.
- 4Choose JPG or WebP (WebP compresses smaller at the same quality).
- 5Download your compressed image and check the new file size.
Many upload forms, email systems and websites reject images larger than 500KB. Compressing a photo under that limit lets it upload successfully without dropping the resolution to something tiny.
This compressor encodes your image at progressively lower quality until it drops below 500KB, using a search that keeps the highest quality that still fits — so you get the smallest visible loss. WebP usually reaches the target at a higher quality than JPG. Everything runs locally in your browser using the HTML canvas — your image is never uploaded to a server, so it stays completely private and there is no waiting for uploads.
Compression keeps your image's width and height and only reduces the file size. If you also need to change dimensions, use one of our resize tools first, then compress.
Need to change the shape, not just the size?
When you resize to a different aspect ratio, you normally have to crop or add bars. Our AI outpainting tool generates new matching background so your photo fills any canvas without losing a thing. Sign in for 3 free AI generations.

No. The tool processes your image entirely in your browser. Your file never leaves your device, which keeps sensitive photos and documents private.
