The tool searches for the highest JPG quality that keeps your image at or under 1 MB (1 KB = 1,024 bytes), and reduces the dimensions in small steps only if quality alone is not enough. Your file is processed on your device and never uploaded.
How to compress an image to 1 MB
- Click Choose your photo or scan (JPG, PNG, WebP, HEIC and more).
- The image is compressed to 1 MB or slightly less automatically.
- Check the size shown, then press Download and upload the file to your form.
When you need a 1 MB image
Many portals, email systems and marketplaces limit uploads to 1 MB per image. Compressing to just under 1 MB keeps almost all of the original detail.
Tips for a sharp result at 1 MB
If your photo is over 12 megapixels, the tool may reduce the dimensions slightly to fit. You can also crop away empty background with the crop tool before compressing.

Frequently asked questions
Will my image be exactly 1 MB?
It will be at or just below 1 MB, usually within a few KB. Staying slightly under prevents portals from rejecting it.
Can I compress a PNG or screenshot?
Yes. It is converted to JPG (or WebP if you choose), with transparent areas filled with the background colour.
Is it safe for ID documents?
Yes. The compression happens in your browser; the file is never sent to a server.
Why does the form still say my file is too large?
Some portals count 1 KB as 1,000 bytes. Set the target a few KB lower, for example 1021 KB, and try again.
