How to Compress Photos: A Practical Guide

Compressing a photo takes four decisions: which file, which format, how small, and whether the result still looks right. This guide walks through each one, with the tool right here to follow along.

Image Compressor

Runs on your device — no upload

Drop an image here

or click to browse, or paste from your clipboard with Ctrl/Cmd + V

JPG · PNG · WebP · AVIF · BMP · GIF — up to 40 MB

Step 1 — Add your photo

Drag and drop it onto the drop zone, use the file picker, or simply paste from your clipboard with Ctrl/Cmd+V. The tool immediately shows the filename, format, dimensions and original size.

Step 2 — Choose format and target

Pick JPG for maximum compatibility, WebP for the smallest file, PNG when you need transparency. Then choose a Smart quality level, or switch to Target File Size and enter the exact limit you must meet.

Step 3 — Compress and inspect

Progress updates show each encoding pass. When it finishes, compare the before and after with the slider, and check the reported reduction percentage and final dimensions.

Step 4 — Download and keep your original

Download gives you a cleanly named file such as holiday-photo-optimized.webp. Keep the untouched original somewhere safe, because lossy compression cannot be undone.
