Compress JPG to 1 MB

Some forms, portals and email setups cap uploads at 1 MB. This page is preset to 1,000 KB: add a JPG, PNG or WebP and download a JPG at or under that size.

KB
Drop images here or click to choose JPG, PNG or WebP. You can add up to 20 at once.

Output is always a JPG, and transparent areas turn white. The result is at or under your KB limit, but it is not guaranteed to meet a minimum size. If the form needs a minimum too, check the result before you upload. Need PNG or a transparent background? This tool is not the right fit.

The form also asks for pixel dimensions

Nothing is uploaded. Your images are compressed on this device.

Steps

  1. The limit box above is set to 1000 KB. This tool counts 1 KB as 1000 bytes, so the result is at most 1,000,000 bytes and fits under a 1 MB limit under either definition.
  2. Add one photo or several (up to 20 at once).
  3. Open the thumbnail to check sharpness, then download each JPG.

Why a 1 MB result usually looks good

1 MB is a generous budget. A photo straight from a modern phone is often several MB, and the tool looks for a high JPEG quality that still fits. For some photos the difference from the original is hard to see on a normal screen. Very large images are first reduced to about 16 megapixels, which is still far more than a form or screen needs.

When this page is the right choice

  • Email attachments: shrink several photos so they all fit in one message.
  • Forms with a 1 MB cap: some claim, application and support forms set this limit, so check the size your form states.
  • Web and blog images: if load speed matters more than a 1 MB cap, try 200 KB.

Before you upload

  • The output is always JPG, and transparent areas turn white. If you need PNG or transparency, this tool is not suitable.
  • Compressing removes camera details and GPS location from the file, because the image is re-encoded.
  • If the image is already under 1 MB, you may not need this step at all.
  • If the tool says it cannot reach the limit, crop the image first and try again. More detail is in the how-to guide and FAQ.
