How to get images under 1 MB

A 1 MB limit is common for attachments, school portals, and lightweight CMS uploads. This compressor runs locally: pick JPEG or WebP, reduce quality until the output fits your budget, and download.

  • Compare original vs compressed size before downloading
  • Try WebP first for photos—it often beats JPEG at the same visual quality
  • If the canvas is huge, resize in an editor first, then compress here

Why your file might be over 1 MB

High-resolution phone photos and PNG screenshots can be multiple megabytes even when they look modest on screen. Compression removes redundant data; for photos, a modest quality setting rarely looks different on the web.

If you still cannot reach 1 MB without visible artifacts, reduce pixel dimensions to match how the image will actually display.

Privacy

Optimization runs in your browser—your file is not uploaded for compression. The main hub (/image-compress) uses the same engine with the default long-form guide.

Slightly, depending on your quality setting. At 80% quality the difference is usually not visible to the naked eye.
