Why people compress to 1 MB

If something is asking you to get under 1 MB, the interesting question is why the file was so far above it.

  • Email attachment limits
  • Upload caps on forums and support tickets
  • Trimming a phone photo before sharing it
  • Anywhere a 10 MB original is simply wasteful

Why is your photo over 1 MB in the first place?

One megabyte is a generous limit, and a photograph almost never needs to be near it. The reason phone photos arrive at 5–12 MB is that modern sensors capture 12 to 48 megapixels and save at very high quality by default — you are storing detail that no screen will ever show. Compressing to 1 MB usually throws away nothing you can perceive, which is why this target almost always succeeds without any resizing.

How the target is reached

Quality is searched before resolution, because losing a little quality is far less noticeable than losing pixels. The tool encodes your image repeatedly, halving the range each time, until it finds the highest quality setting that still lands under 1 MB. Only if even the lowest quality is too large does it begin scaling the image down, and it re-searches quality at every smaller size rather than simply shrinking until it fits.

One format note worth knowing: PNG is lossless, so a quality setting does nothing to it. Hitting a size target with PNG is possible only by reducing dimensions. For photographs, WebP or JPEG will always get you further.

Drop the file into the box above. The target is already set to 1 MB, so the tool searches for the highest quality that still fits and applies it. Nothing is uploaded — the whole thing runs in your browser.

At 1 MB you can expect no resizing needed for almost any photo — quality alone gets there. The tool always exhausts the quality range before it reduces resolution, so it gives up as little as the target allows.

WebP produces the smallest file at a given quality and is supported by every current browser. Choose JPEG if something specifically requires it, such as an older upload form. PNG is lossless, so a size target can only be met by reducing dimensions — avoid it for photographs.

No. Compression happens in a canvas element on your own device, so the file never leaves your computer. That also means there is no upload wait and no size cap.
