How do I compress a JPEG to 1MB?

Drop it in above — the tool automatically finds the highest JPEG quality that still lands under 1MB, so you don't have to guess a percentage yourself.

What quality is a 1MB photo?

It depends on the original, but a typical 12MP smartphone photo (around 4000x3000px) usually compresses to about 1MB at roughly 85% JPEG quality — high enough that the difference from the original is hard to spot at normal viewing sizes.

Is 1MB too big for email?

No — most email providers cap total attachment size well above that, often 10-25MB. 1MB is a safe, common target specifically for portals and forms that state their own stricter limit, not a general email concern.

Will compressing to 1MB reduce quality noticeably?

Usually not. We search for the highest quality that fits your target rather than applying a fixed compression level, so most photos stay clearly sharp at 1MB — very high-resolution originals may show mild softening.

What file formats does this accept?

JPEG, PNG and WebP as input. Output is JPEG (PNG transparency is composited onto white).

How it works

1Drop your image — everything runs in your browser, nothing is uploaded anywhere.
2We binary-search JPEG quality (typically landing around 75-90%) to find the highest setting that still fits under 1MB.
3If quality alone can't reach 1MB, dimensions are downscaled slightly as a last resort, keeping as much detail as possible.

When you need this

A full-resolution phone photo attached to an email bounces back with a "message too large" error
A job site, portfolio, or admissions portal caps photo uploads at 1MB and rejects anything bigger
Inserting a photo into a Word or Google Docs document without bloating the file size for everyone who opens it
