Frequently asked questions
Will a 1 MB photo look different from my original?
Rarely. Phone cameras save far more detail than a screen can show, and the tool keeps the highest quality that fits in 1 MB, so most people cannot tell the two apart.
Is 1 MB here 1,000 KB or 1,024 KB?
The tool aims below 1,000,000 bytes, the stricter of the two, so the file is accepted whichever way a website counts.
Why was my 800 KB photo not changed?
It already fits under 1 MB, so the tool kept your original rather than re-compressing it. Set a lower limit if you want it smaller.
Is my image uploaded when I compress it to 1 MB?
No. The compression runs in your browser, so your photo never leaves your device. That also makes it quick: there is nothing to upload or download from a server.
What fits in 1 MB
Many websites, forms and help desks cap uploads at 1 MB. At this size a photo keeps around 1,730 × 2,310 pixels, enough for a full-screen view on most laptops, so the result usually looks the same as the original.
As a rough guide, a typical photo fits in 1 MB at about 1,730 × 2,310 pixels while still looking clean. Pictures with plain backgrounds, such as signatures and documents, can keep more pixels; busy, detailed photos need fewer.
