How to compress images without ruining quality

A practical guide to shrinking image files while keeping text, edges, and photos looking clean.

Guide

Compression works best when you pick the right format first, then tune quality and dimensions instead of forcing one aggressive setting.

Choose the right output format first

Compression settings matter, but format choice matters more. A PNG screenshot may shrink dramatically when exported as WebP or AVIF, while a JPG photo often only needs a moderate quality adjustment.

If a file must keep transparency or crisp interface edges, test the output rather than assuming the smallest file is the best file.

Resize before you chase tiny quality gains

Huge source dimensions are a common reason for bloated files. If the final image only appears at 1200 pixels wide, keeping a 6000-pixel export usually wastes bytes.

Resizing first often gives better-looking results than pushing quality far lower on an oversized image.

  • Reduce dimensions to match the real display size.
  • Use moderate quality settings before trying extreme compression.
  • Strip metadata only when you do not need embedded camera or editing information.

Check the content that breaks first

Look closely at text overlays, gradients, skin tones, logos, and transparent edges. Those areas reveal compression damage much faster than a general glance at the whole image.

When a compressed version looks soft or blocky, switch format, raise quality a little, or export a smaller dimension target instead of forcing the same settings.

Guide FAQ

Extra context around the workflow and tradeoffs in this guide.

Does AVIF always create the smallest file?

It often wins on size, but not every image benefits enough to justify the slower encode time or workflow complexity.

Should I strip metadata from every image?

Only when you do not need it. Removing metadata can help file size, but it also removes camera and editing details.

Why does a compressed PNG sometimes stay large?

Lossless PNG files can remain heavy, especially for photos. Converting to WebP or AVIF is often more effective than pushing PNG compression harder.

What is the safest way to compare versions?

Check the original and compressed file side by side at the size users will actually see, then inspect edges, text, and gradients.
