Frequently Asked Questions

Get Answers to Your Questions About Our Chat Software and Features

How can I use Cloudinary’s Image resize to 20KB tool to reduce file size without losing quality?

Cloudinary provides an Image resize to 20KB tool that works with JPG, PNG, HEIC, and other formats, bringing files down to 20KB or less while preserving clean, readable visuals. Simply upload or drag in your image and the optimization begins instantly. The system relies on f_auto to deliver the most efficient format (such as WebP or AVIF) and q_auto to balance sharpness with aggressive size reduction. It’s an ideal solution for mobile-focused products or media-heavy sites that need ultra-light images to accelerate loading and enhance user experience.

Can I automate Image resize to 20KB conversions using Cloudinary’s API?

Absolutely. Cloudinary’s API makes it easy to automate Image resize to 20KB workflows at scale. You can upload files with transformation parameters like q_auto, f_auto, and fl_lossy to reduce images to the 20KB range automatically. These options can also be bundled into an upload preset so every incoming asset follows the same size rules—ideal for platforms that handle large volumes of user-uploaded images or need hands-off optimization.

Is resizing an image to 20KB considered “lossless”?

To produce a 20KB file, Cloudinary applies perceptual, visually lossless optimization that adapts compression to the image’s specific content. This approach maintains sharp edges, important textures, and key visual features, so any quality shift is minimal and usually imperceptible at normal display sizes. Fully lossless formats often exceed 20KB, so if you need exact pixel fidelity, choose PNG or lossless AVIF/WebP and expect larger outputs. For most photos, graphics, and marketing assets, perceptual optimization provides a compact result with no meaningful visual difference. If you notice artifacts, you can increase the quality level slightly or scale down dimensions to stay close to the 20KB target while keeping the image looking clean.
