Frequently Asked Questions

Get Answers to Your Questions About Our Chat Software and Features

How do I compress a PNG to 400KB with this tool?

Use Cloudinary’s Compress png to 400KB solution to shrink JPG, PNG, or HEIC images to 400KB or below with great visual fidelity. Just drop in your file or click to upload and the tool begins compressing on its own. We use smart format selection (f_auto) and dynamic quality control (q_auto) to keep your images lightweight yet sharp. Ideal for developers and marketers wanting faster image delivery on visual-heavy pages.

Can I batch-compress PNG files to 400KB?

Yes, Cloudinary’s robust API enables full control over Compress png to 400KB processing. Upload images via the API and include transformation parameters like q_auto:low, f_auto, and fl_lossy to reduce size on the fly. Integrate constraints in your asset management pipeline to enforce compression across all uploads—great for automation.

Is the compression to 400Kb “lossless”?

To achieve 400KB, we rely on perceptual, visually lossless optimization that tunes compression to image content. The resulting quality change is minor and generally imperceptible at typical sizes, as edges, textures, and important details are preserved while redundancy is removed. Depending on the source, lossless output may exceed 400KB; for bit-perfect needs select PNG or lossless AVIF/WebP and anticipate larger files. For most photo and marketing scenarios, perceptual settings provide a compact image with no meaningful visual trade-off. If you notice artifacts, lift quality slightly or reduce dimensions to remain near 400KB and keep presentation intact.

Can I compress to other sizes or only to 400Kb?
