How to reduce an image below 1 MB without ruining quality

A practical order for adjusting resolution and compression quality.

Why this order matters

File size depends on pixel count, image format and compression quality together. Lowering quality first can create visible blocks around text and faces, so it is usually better to remove unnecessary resolution before applying stronger compression.

Check the destination first

If the receiving website or authority publishes its own format and size requirements, follow those instructions first. Keep the original and work on a copy.

Recommended workflow

  1. Check the destination’s required dimensions, format and maximum file size.
  2. Resize to the largest pixel dimensions you actually need while preserving the aspect ratio.
  3. Reduce JPG or WebP quality gradually until the result is below 1 MB.

Checks before saving

Zoom in on the result and open it once in the environment where it will be used. Automated calculations and conversions are convenient reference tools, not a substitute for the receiving organisation’s final decision.
