How to compress an image to 1MB
Quick answer: add your image above, keep the target at 1MB and click Compress. The tool finds the highest quality that fits under 1MB and only shrinks the dimensions if needed. The JPG you download is guaranteed to be 1MB or smaller.
- Add your image (JPG, PNG, WebP or iPhone HEIC).
- Confirm the target — or type any other KB value.
- Compress and download one file or a ZIP.
When do you need 1MB?
- Online forms and portals that reject files over 1 MB.
- Sharing many photos by email or chat.
- Keeping full-resolution look while cutting 5–10 MB phone photos down.
Photos under 1 MB still look sharp on screens and in normal prints.
