How to Reduce Photo File Size — Without Wrecking Quality (In Your Browser)

Smartphone photos routinely run 5–10MB each these days. So they keep bumping into email attachment limits and the upload caps on submission forms (say, 2MB). Here are the practical ways to cut the size while keeping as much quality as possible.

1. Switch the format to WEBP (biggest win)

At the same quality, WEBP is roughly 25–35% smaller than JPG. If the goal is posting or sharing, this alone makes a noticeable difference.

2. Lower the quality (compression)

JPG and WEBP let you trade quality for size. Around 80–85% is usually indistinguishable to the eye while dropping the size substantially. The image converter shows the estimated size before you convert, so you can compare settings on the spot.

3. Many photos at once

If you have dozens of photos, use batch conversion to change format and quality all at once and download them as a ZIP.

Avoid these

• •Saving photos as PNG makes them heavy — use JPG or WEBP for photos.
• •Force-compressing an already small file barely shrinks it and only hurts quality.
