ExactKB is an independent image utility for files that must fit a byte ceiling. It processes supported images in your browser, searches for a fitting encode, and shows output dimensions and exact bytes.
Who publishes the site
ExactKB is developed by Ultra Edge Labs, a software development company. For support or corrections, contact [email protected].
What the tool does
The compressor decodes image pixels, resizes when needed, and writes a new JPG, WebP or PNG. It keeps processing on the device and does not offer an image-upload API, account system or server file locker. Its output is a new image; preserve your original.
What a result means
A successful result meets the selected byte ceiling. It does not certify an application photo, preserve original metadata, or guarantee an exact padded size. Size presets are conveniences. Always check the current destination’s format, minimum dimensions and composition rules.
How we document behavior
The guides describe the encoder’s practical limits and include downloadable measured samples. Those samples are generated test images, not customer files. Individual photographs and browsers can produce different results. Official application guidance is linked where relevant, and the authority’s current instructions take precedence.
Funding and contact
The current tool is free to use. If advertising is introduced, it must be visually distinct from tool and download controls, with privacy information updated for the actual implementation. Read the privacy policy, terms, or contact page.
