Image Compressor

What this tool does

Re-encode an image as JPEG, WebP or PNG, then compare the actual output size and preview. Savings depend on the image and selected settings.

Need scalable SVG paths for a logo or icon? Try PNG/JPG to SVG (VTracer). Tracing approximates the artwork; inspect small text and fine details before using the result.

Dimensions

Pixel width and height stay unchanged. Use the resizer to reduce dimensions.

Quality control

The quality slider affects JPEG and WebP. PNG encoding ignores the quality setting.

Transparency

PNG and WebP can retain transparency. JPEG uses a white background.

Processing and price

Free, one image at a time, processed in your browser. A smaller output is not guaranteed.

How to use it

1. Choose an image and note its original byte size.
2. Try JPEG or WebP at 80% quality, then compare at 60%. Inspect fine details in both previews.
3. Download only if the quality and size suit your task. Keep the original if the result is larger.

Try a reproducible example

Use the same sample for each test. Record the browser, format, quality and output bytes. PNG may be larger than the source, and the PNG result should not change when only the quality slider changes. These are test instructions, not a promised compression percentage.

Synthetic test pattern with transparent areas. No personal photos or documents.
