Compress image to 1MB

About this task

A 1 MB limit is the most forgiving common size for photo uploads: profile pictures, receipts, claim attachments and listing photos often cap there. Many phone photos are only a few times larger, so the loss is modest.

The target is 900 KB because sites define a megabyte differently, as 1,000,000 or 1,048,576 bytes. 900 KB is under both, which avoids a rejection for a few bytes. Raise the number if you know the exact limit.

A photo only slightly above 1 MB needs a light quality drop that most people will not notice. A very large camera file needs more, and may also be scaled down in pixel size. The result list shows the dimensions whenever they changed.

If your image is already under the target in the chosen format, it is kept as it is. PNG screenshots can be large; convert to JPG output for a real size target, because PNG can only be resized.

How to do it

1. Add your photo or photos. JPG, PNG, WebP and other common formats open, and you can add several at once.
2. The target is already set to 900 KB and the output is JPG. Change either if your site needs something else.
3. Press Compress. Quality is lowered first, and the picture is made smaller only if quality alone is not enough.
4. Check the size shown for each image, then download. Several images come as one ZIP.

Compress image is a DocPro Pro tool on the web. You can open it, choose your file and set every option without an account; the final step asks you to sign in to DocPro Pro (A$5.99/month after a 7-day free trial, cancel anytime). Free tools never ask.

Frequently asked questions

Why is the target 900 KB?

It is a safe margin below both common definitions of 1 MB. Type another value if your site is specific.

Will it keep the aspect ratio?

Yes. When the picture is made smaller, width and height shrink together.

Does it work for scanned documents?

Yes, though text edges show compression sooner than photos. Check the result is legible.
