Compress HEIC Images
Shrink HEIC photos from iPhone — or convert to JPG for easier sharing.
Your images stay on your device. Nothing is uploaded.
HEIC (also written HEIF) is the default photo format on modern iPhones. It is already efficient, but the files coming off a 48-MP camera are still 2–4 MB each — too much for email, forms, and many web uploads. Image-Compressor.uk reduces HEIC files in the browser, and can convert them to JPG or WebP for compatibility with anything that does not yet support HEIC.
Compression is local — your photos never leave your device. Drop one or many below to start.

Frequently asked questions
- How do I compress a HEIC image?
- Drag and drop your HEIC file (or click to select) and the compressor reduces its size automatically using the pre-tuned settings on this page. Adjust the quality slider, max dimension, or output format for a stronger or gentler compression. Everything runs in your browser — your file never leaves your device.
- Does compressing a HEIC reduce quality?
- Most HEIC compression goes via a decode-to-canvas-then-re-encode pipeline, which is technically a re-compression step. Quality loss is minimal at q80, and the convenience of sharing as JPG is usually worth it. You can preview before downloading and tune the quality slider until the size and quality balance feels right.
- Is the HEIC compressor free?
- Yes. Image Compressor is free, requires no signup, and has no upload limits. For batches, use the bulk compressor.
- Are my HEIC files uploaded to a server?
- No. Compression happens entirely in your browser using the Canvas API. Files never touch our servers — that is what makes the tool both private and fast.
- What is the largest HEIC I can compress?
- Single uploads are capped at 25 MB to keep the tool responsive in the browser. Very large files may be slower because compression uses your device's memory and CPU rather than a server.
