Lots of CMSs and forums stop at 2 MB per image. Drop in your iPhone photos and get JPGs that slip under the limit, usually at full resolution.

This tool runs entirely in the browser: photos are decoded and encoded on the visitor’s device and are never uploaded. It is free, needs no sign-up and works offline after the first visit.

## How to use it

1. Drop your HEIC photos above, or paste one straight from the clipboard.
2. Each one is compressed to the best quality that fits under **2 MB**, starting from quality 90.
3. Download and upload to your site, forum or app without hitting the size error.

## The 2 MB wall

You took a nice photo, converted it to JPG, and the upload still fails: "File exceeds maximum size of 2 MB." This happens a lot, because HEIC is roughly twice as efficient as JPG. A 2 MB HEIC turns into a JPG that's too big for the very limit it would have passed as HEIC.

You'll see 2 MB caps on:

- **Content management systems** and hosted blogs
- **Forum and community software**, for attachments and galleries
- **Help desks and support tickets**, for screenshots and photos
- **Club, school and church websites** run on shared hosting

## Full resolution, most of the time

2 MB is a comfortable budget. We start at quality 90 and step down only as far as needed. For a typical 12 MP iPhone photo that usually means a high quality JPG at the original pixel size, so you can still crop or zoom later.

Very detailed scenes or 48 MP photos may need a gentle downscale. We only shrink dimensions after quality has gone as low as it sensibly can (about 55), so the photo you get is always the best one that fits.

## Quality vs size at a glance

| Starting photo | Likely result under 2 MB |
| --- | --- |
| 12 MP, simple scene | Full size, high quality |
| 12 MP, very detailed | Full size, slightly lower quality |
| 48 MP | Scaled down to fit |
| Screenshot or graphic | Full size, near-original quality |

## Blogging with iPhone photos

If you run a WordPress site, [Convert HEIC for WordPress](https://ihateheic.com/convert-heic-for-wordpress) has settings tuned for blogs. For pages where speed matters more than full resolution, a [500 KB](https://ihateheic.com/compress-heic-to-500kb) version or a [resize](https://ihateheic.com/resize-heic) to 1920 px loads much faster for readers.

## Colours that match your phone

iPhone photos are captured in Display P3, a wider colour range than older screens use. We embed that colour profile in the JPG so your photo looks the same on your site as it did on your phone. If a forum strips the profile and colours look flat, switch Colour to "sRGB" and compress again.

## Offline-ready

After one visit the compressor is cached, so you can prep a batch of photos on a train with no signal and upload them later. Nothing ever needed to leave your device in the first place.

## FAQ

### Will compressing to 2 MB keep my photo's full resolution?

In most cases, yes. 2 MB is enough room for a 12 MP photo at a high JPG quality, so dimensions usually stay exactly as shot.

### Why is my converted JPG bigger than 2 MB in the first place?

HEIC is about twice as efficient as JPG. A 2 MB HEIC can easily become a 3 to 4 MB JPG at high quality, which is why a plain conversion often fails a 2 MB limit.

### Which sites use a 2 MB image limit?

It's common on content management systems, forum software, community platforms and support desks, though each site sets its own value. Check the error message for the exact number.

### What about 48 MP photos?

Larger photos from 48 MP cameras have far more pixels, so they may need to be scaled down to fit 2 MB. The tool does that automatically when quality alone isn't enough.

### Can I choose WebP instead?

Yes. WebP usually reaches the same size at a higher quality. Use it if your CMS or forum accepts WebP uploads.

### Is anything sent to a server?

No. Your photos are compressed in your browser and never uploaded by us. The only upload is the one you do yourself to your site.
