Compress HEIC Files to 20KB in 3 Steps
Reduce HEIC files to a practical upload size while keeping them usable for iPhone photos and Apple ecosystem images.
Drag in one file or a full batch. The uploader handles typical HEIC workflows such as email attachments, website assets, and portal submissions.
Pick 20KB when you need to meet a form limit, shrink page weight, or stay under an attachment cap. The engine balances compression ratio and visual quality automatically.
Download the compressed output individually or as a ZIP archive, then use it immediately for uploads, publishing, sharing, or storage cleanup.
What to Expect When You Compress to 20KB
At 20KB, larger images will show visible quality reduction. Best suited for thumbnails, previews, and small web graphics displayed under 800×600 pixels.
For full-resolution photographs, consider a larger target like 200KB or 500KB. At 20KB, HEIC files work best for web thumbnails and compact display sizes.
HEIC is commonly used for iPhone photos and Apple ecosystem images. Typical originals land around 1–4 MB, so compressing to 20KB is most useful when you need to meet a strict upload or performance target.
Common Use Cases for This Size Target
These are the most practical reasons people compress HEIC files to 20KB.
Embed HEIC previews directly inside email bodies. Most email clients display 20KB images inline without triggering download prompts or security warnings.
Lightweight 20KB assets load instantly on cellular connections, keeping app bundle sizes and per-session bandwidth costs to a minimum.
Ideal for product listing grids, user avatars, and card layouts where fast load speed matters more than pixel-level detail.
