Done! Your image is ready
Note: the result is slightly under the target (padding not possible for this size), which is accepted everywhere.

Frequently asked questions
How does the exact-KB compression work?
The tool re-encodes your image on a canvas and runs a binary search over the quality setting until it finds the largest quality that fits under your target. It then pads the file with format-safe bytes to reach the exact size — a standard technique that every image viewer accepts.
Is my image uploaded to a server?
No. The whole process — decoding, resizing, compressing and padding — runs inside your browser using a Web Worker. Your image never leaves your device.
Which formats are supported?
You can load JPG, PNG, WebP, GIF, BMP and AVIF images. The output is JPG or WebP, which are the formats that support adjustable compression quality.
Why would I need an exact file size?
Many government portals, job applications, exam registrations and upload forms enforce strict limits like "photo must be 50 KB" or "maximum 100 KB". This tool guarantees your file meets the requirement without trial and error.
Will the quality suffer?
The tool always finds the highest possible quality that fits your target. If the target is very small for a large photo, it also reduces dimensions smartly to preserve as much detail as possible.
