Image Compressor

Reduce file sizes while maintaining quality. Optimize JPEG, PNG, WebP, and GIF. Keeps the original format (no conversion). Compression happens in your browser; files are never uploaded.

Drop or choose an image to compress

Drag & drop an image here or click to browse

JPEG, PNG, WebP, GIF (max 32 MB). Original format is preserved. Processed locally in your browser; file is not uploaded.

Compression Decision Guide

Pick your target first, then tune quality intentionally instead of guessing.

Goal A: smallest possible file for previews

Use lower quality only after you confirm dimensions are already final. For tiny previews, slight artifacts are usually acceptable.

Goal B: balanced web quality

Start around medium-high quality, compare text edges and faces at 100%, then move quality in small steps until size and visual quality meet your target.

Goal C: text and graphics clarity

Keep higher quality for text-heavy visuals. If letters look muddy, use a format/content strategy adjustment instead of forcing aggressive compression.

Compression runs in your browser and keeps the original format.

How To Tune Quality Without Guessing

Treat compression as a controlled test: lock dimensions, move one setting, compare output, then decide.

The most common mistake is changing too many factors at once. Keep dimensions fixed, then adjust quality in small steps and inspect the same regions in each output (text edges, faces, gradients, dark shadows). This makes quality decisions repeatable.

Compression QA Checklist

Run this quick checklist before downloading the final file.

Check 1: delivery target

Confirm whether you are optimizing for web page speed, email limits, or archive storage. Your target decides how aggressive compression can be.

Check 2: visual critical points

Inspect faces, text, logos, and smooth gradients. If those zones fail, increase quality slightly or adjust format strategy.

Check 3: avoid repeated losses

Do not recompress an already compressed output repeatedly. Go back to source and produce a fresh final export.

Check 4: fallback behavior

If compression does not produce a smaller file, keep the original. Bigger "compressed" output is a failed optimization.
