Compress Image to 50 KB
Compress a JPG or PNG photo to under 50 KB for photo upload fields on most online application and registration forms. Free and private — the image is resized and re-compressed in your browser, never uploaded.
To compress an image to 50 KB, this tool automatically searches for the highest JPEG quality that lands under 50 KB, stepping the dimensions down if needed. Drop your photo and it targets 50 KB for you. If a file genuinely can't reach 50 KB while staying legible, it delivers the smallest possible version and tells you the exact size. Everything runs in your browser.
🔒 Compression runs locally — your image is never uploaded.

Frequently asked questions
How do I compress an image to 50 KB?
Load your image on this page — it automatically finds the best quality that keeps the file under 50 KB. You'll see the final size before you download.
What if my photo can't reach 50 KB?
The tool lowers quality and, if needed, the dimensions to get as close as possible. If 50 KB is impossible without destroying the image, it shows you the smallest size it could achieve instead of pretending it worked.
Is my image uploaded?
No. Compression happens entirely in your browser — the file never leaves your device.
