Compress iPhone Photos (HEIC)
Reduce the size of iPhone photos for email, forms, and websites. HEIC files are opened in your browser as JPG, then compressed while you control the balance between size and quality.
How to compress iPhone Photos (HEIC)
- 01.
Add your HEIC photos.
- 02.
Move the quality slider; the estimated size updates as you go.
- 03.
Process, compare the real sizes, and download the JPG files.
Why the result is a JPG
Browsers cannot save HEIC, so compressed photos are saved as JPG, the format every form and website accepts. HEIC is very efficient, so a JPG of the same quality is usually larger than the original HEIC; compression brings it back down. The "before" size shown is that of the JPG made from your photo: a 2.4 MB iPhone photo becomes a 3.6 MB JPG first.
Meeting an upload limit
Forms often limit uploads to 1 or 2 MB. Try a quality of 70–85 first. iPhone photos have about 12 megapixels, so resizing to about 2000 pixels on the long side before compressing is usually the most effective way to reach the limit.
From iPhone photo to upload limit
Pick the goal and follow the matching steps:
| If you need | Do this |
|---|---|
| Under 2 MB for a form | Resize to about 2000 px on the long side, then compress at 75–85 |
| Photos for a website | Resize to the display width, then compress at 75–85 |
| Photos for email | Compress at 70–80; resize if the attachment is still too big |
| Keep every detail | Keep the HEIC original and compress only a copy |
Common problems and how to fix them
The photo got bigger instead of smaller
The JPG made from a HEIC is larger than the HEIC. Lower the quality or resize the photo; if the result still cannot beat the JPG, the JPG is kept.
I need a HEIC file back
Browsers cannot create HEIC. Keep the originals on your phone and use the JPG copies for sharing.
The photo looks blocky
The quality is too low for this photo. Raise it to 75–85 and process again.
