Image to Exact KB

Job portals, exam forms and uploads often demand an exact size like “under 100 KB”. Set your target and Piclizer searches quality levels — shrinking dimensions only if it must — to land precisely on it.

FAQ

It probes several quality levels at full resolution, then bisects to the best quality that fits. Only if that fails does it step dimensions down gradually.

Only when necessary. Resolution is preserved whenever the target can be met with quality tuning alone.

The tool returns the smallest file it could produce and tells you honestly that the target could not be met.

Usually WebP, then JPG. PNG is lossless and cannot reach very small targets for photos.

Never. Every trial encode runs in your browser.

About this tool: Image to Exact KB

Hit an exact file size in kilobytes

The Exact Size tool does what ordinary compressors cannot: it makes a JPG, PNG or WebP image land precisely under a kilobyte target you type — 100 KB, 50 KB, whatever the form demands. Instead of guessing quality values, you state the size and the tool searches the encoding space automatically until the file fits.

Government portals, visa applications, scholarship systems and job sites famously enforce hard limits like “maximum 100 KB”. Overshooting means rejection; compressing blindly means losing far more quality than necessary. This tool hits the limit with the highest quality the target allows, nothing wasted in either direction.

Everything is computed locally in your browser: the image is re-encoded repeatedly on your device until the target is met, then offered for download. For consistent results across a whole set of images, process them one by one — each gets its own optimal setting for the same size cap.

Like every Piclizer tool, this one runs entirely in your browser — your files stay on your device.
