The resize image to 30KB tool by Cloudinary makes it easy to reduce the size of images (JPG, PNG, HEIC) down to 30KB without losing clarity. Simply upload your file or drag it into the tool to trigger instant optimization. It uses f_auto and q_auto to automatically select the ideal format and compression settings. This is ideal for mobile apps and image-heavy sites looking to boost loading speed and overall user experience.

Absolutely. With Cloudinary’s API, automating resize image to 30KB workflows is simple. When uploading via the API, you can apply settings like q_auto:low, f_auto, and fl_lossy to automatically reduce file size. You can also chain transformations or define size thresholds to ensure every upload is optimized — perfect for high-volume or fully automated pipelines.

To reach a 30KB target, we use perceptual, content-aware optimization designed to stay visually lossless. Any quality reduction is minimal and usually unnoticeable at standard viewing sizes because key edges, textures, and important detail are preserved while unnecessary data is removed. Fully lossless methods often exceed 30KB, so if exact pixel accuracy is needed, stick with PNG or lossless AVIF/WebP and expect larger file sizes. For most photos and marketing visuals, the perceptual approach produces a lightweight file with virtually no visible change. If you ever notice artifacts, you can bump the quality slightly or reduce the image dimensions to stay close to the resize image to 30KB target without sacrificing appearance.
