Compress image to 1 MB
Email providers, chat apps, and many forums cap uploads around 1 MB or a few MB. One modern phone photo can blow past that on its own. This tool brings any image under 1 MB with virtually no visible quality loss.

When 1 MB is the limit
1 MB is a practical ceiling for sending images around rather than displaying them on a busy web page. It keeps attachments and messages quick to send and receive, so it shows up wherever files move between people.
- Email attachments where you're mindful of the recipient's inbox.
- Chat and community apps with per-file upload caps.
- Forums and support tickets that limit attachment size.
- Shared drives and wikis with per-file quotas.
Why your phone photo is so much bigger than 1 MB
Modern phone cameras capture 12–50 megapixels and often store extra data like HDR layers and depth maps. A single shot can easily be 3–8 MB. Almost none of that extra weight is visible once the image is viewed on a screen at normal size.
Recompressing to 1 MB keeps what your eyes actually see and discards the rest, so the result looks the same in a message or document while being a fraction of the size. At this generous target you can keep large dimensions (1920–2560 px) and still fit comfortably.

Frequently asked questions
Why is my phone photo so much bigger than 1 MB?
Modern phone cameras shoot 12–50 megapixels and store extra data like depth maps. Most of that is invisible on screen — recompressing to 1 MB keeps what your eyes see and drops the rest.
Is my image uploaded to a server?
No. Compression happens entirely in your browser using the Canvas API — your image never leaves your device, which is also why it's instant.
What if my image can't reach 1024 KB?
The tool first lowers the compression quality, and if that's not enough it gradually reduces the dimensions until the file fits under 1024 KB. Extremely detailed images may lose visible quality at very small targets — the preview shows you exactly what you'll get.
