Compress Image to 30KB Online Free

Why Compress an Image to 30KB?

A 30KB file size limit is common across school admission portals, competitive exam registration systems, and certain corporate HR platforms. It sits between the strictest government limits (20KB) and the more relaxed general-purpose limit (50KB), which makes it a tricky size to hit manually without trial and error. Online registration portals for engineering entrance exams, medical admissions, civil services, and competitive fellowships commonly enforce this limit because their database systems need to store thousands of applicant photos efficiently.

Our tool removes the guesswork entirely. Rather than manually exporting and re-exporting from Photoshop or GIMP until the file size happens to fall under 30KB, you upload once and the algorithm does the rest. It uses a binary-search compression loop that starts at high quality and progressively narrows to the highest quality setting that still produces a file of 30KB or less. This gives you a noticeably sharper result than simply dragging a quality slider. The compression runs entirely client-side in your browser, so your photo data stays on your device and is never transmitted anywhere.
