Cloudinary provides a powerful tool to resize PNG, JPG, HEIC, and other image formats down to ≤25KB while preserving clean, sharp visuals. Simply drag-and-drop or upload your files, and optimization happens instantly. With intelligent format delivery (f_auto) and adaptive quality tuning (q_auto), your images stay lightweight without losing clarity. Ideal for content-heavy sites and apps aiming for faster load times and higher user engagement

Absolutely. Cloudinary’s API lets you automate the resize images to 25KB process from end to end. When uploading, you can apply settings like q_auto:low, f_auto, and fl_lossy to reduce file sizes automatically. Add size rules or conditional transformations in your upload flow so every image is resized to the required limit—ideal for handling large volumes at scale.

To reach 25KB, we rely on perceptual, visually lossless optimization that tunes compression to the content of each image. Any quality shift is very small and usually not noticeable at normal sizes, because we keep edges, textures, and key details while removing only redundant information. Strict lossless encoding can exceed 25KB, so when you need bit-perfect fidelity (for example UI icons, line art, scientific figures), choose a lossless path such as PNG or lossless AVIF/WebP and plan for larger files. For most photos and marketing creatives, the perceptual approach yields a lightweight file with virtually no visible change. If you spot artifacts, nudge quality upward or trim dimensions slightly to stay close to 25KB and maintain a clean look.
