Compress Image to 1 MB – Reduce Large Photos Online

One megabyte is about twice as much as 500 KB and ten times as much as 100 KB. For most photos that is enough room to stay sharp at the size people normally view them, so the loss is small.

It is also a very common cap. Many forms, ticket systems and online shops use 1 MB for pictures, which is why this size is searched for so often.

To get under the limit, the tool first tries to lower the JPG or WebP quality. Only if that is not enough does it reduce the width and height, and the card then shows the new size.

• A large phone photo may lose a lot of file size with almost no visible difference.
• A picture that is already small may not change at all, and the card says so.
• A scanned page with fine print should be zoomed in on after compressing, to check that the text can still be read.
• A PNG becomes WebP or JPG when you set a size limit, because PNG is lossless and a quality setting does not shrink it.

If you only want to send pictures in a message or put them on a web page, a limit well below 1 MB is often fine. Try 200 or 500 KB and compare the results side by side.

Smaller files load faster and use less data, but only go as low as the picture can take without looking worse.

This tool counts 1 MB as 1,048,576 bytes. A website that counts 1 MB as 1,000,000 bytes would see a file of exactly 1 MB here as slightly too big. For strict limits, change the unit to KB and enter 950.

Also compare the file type and the pixel size with the instructions of the site you upload to. They can differ between sites and they change over time.
