About this setting
What 1 MB is good for
1 MB is the limit many forms, help desks and older website systems set per image. At that size a JPG can hold a 12- to 24-megapixel photo at high quality, so the tool usually lowers the quality only a little and keeps the full resolution. The target is decimal — 1,000,000 bytes — so the file also fits a limit written as 1,024 KB.
It is also a good size before sending photos through chat apps that recompress large images themselves: a file you have already compressed carefully is less likely to be degraded again.
Tips
- iPhone photo in HEIC? Convert it to JPG first if the form needs JPG, then compress it here.
- Very large files, such as 50-megapixel photos, may also be reduced in pixel size to fit 1 MB.
- Keep your original: compress a copy for sending, not your only file.

FAQ
Good to know
Does 1 MB here mean 1,000 KB or 1,024 KB?
The tool aims for under 1,000,000 bytes, which is also under 1,024 KB. Either way the file fits a form that says 1 MB.Will the photo keep its full size?
In most cases, yes. Only images above roughly 25 megapixels, or with a great deal of fine detail, are also scaled down to stay under 1 MB.Can I compress several photos at once?
No, the tool handles one photo at a time. Download the result, then choose the next photo; it takes a few seconds each.
