About Compress JPG to 500 KB
500 KB is the sweet spot for portal uploads that want good image quality but still cap file size — think university applications, online resumes, insurance claims, and product photos for marketplace listings. This tool compresses JPG and JPEG images to sit just under that line.
We search for the best JPEG quality setting that keeps your photo under 500 KB. Because 500 KB is a roomier target than 100 KB, most photos come out with visually indistinguishable quality — you get the file-size savings without the artefacts.
The compression runs entirely inside your browser. No uploads, no signup, no queue. You drop a file in and a compressed copy is ready to download in a second or two.

Compress JPG to 500 KB — Frequently Asked Questions
How do I compress a JPG to 500 KB?
Drop your JPG or JPEG file into the uploader. We try JPEG quality levels from high to low and pick the one that lands just under 500 KB. Click download to save the compressed copy.
Why didn't my image reach exactly 500 KB?
We target 'under 500 KB' rather than 'exactly 500 KB' — a 462 KB output still passes any 500 KB limit, and chasing the exact number would hurt quality for no benefit. If your photo won't fit even at minimum quality we downscale the dimensions once and retry.
Will the photo look noticeably worse at 500 KB?
Usually not. 500 KB is generous enough that most photos keep their perceived quality. You may see minor softening in very busy areas like foliage or fabric patterns, but faces, text, and primary subjects stay sharp.
What file types are accepted?
Standard JPG/JPEG files. If you have PNG, WebP, or HEIC images, use one of our other compression pages or convert them to JPG first.
Is this safe for sensitive photos?
Yes. Everything runs in your browser using WebAssembly. Your files never touch our servers — we do not have servers for file storage.
