Compress an image to 1MB

Drop a photo in and it comes out at or under 1 MB — in your browser, so it is never uploaded anywhere.

What 1 MB is usually for

1 MB is the usual limit on the more generous upload forms, and the point at which most email providers and content systems stop complaining.

What you'll actually get at this size

1 MB is a lot of room. Nothing visible is lost on a normal photo. If a file is fighting a 1 MB limit, the cause is almost always the format rather than the quality: a screenshot or a graphic saved as PNG can be many megabytes, and converting it to JPEG will collapse it — which is exactly what this does.

If your form gives a range, use both numbers. Portals often say "between 20 KB and 50 KB". Most compressors honour only the ceiling, hand you a file far under the floor, and the form rejects it for being too small. And if you also resize to the exact pixel size the form wants, the photo often lands under the minimum naturally — at which point compressing harder cannot help, because shrinking is the wrong direction. The tool below takes both ends of the range, and will raise the file back up to clear the floor.
