Image Resizer & Compressor

Shrink an image to a maximum width or height and compress it as JPEG, WebP or PNG — with a live before/after size comparison. Runs entirely in your browser. ← Workbench

The image is read directly in your browser — nothing is uploaded.

How it works

The picture is scaled to fit inside the limits you set — the aspect ratio is always kept, and images already smaller than the limits are never enlarged. Then it is re-encoded in the chosen format: JPEG for photographs, WebP when size matters most, PNG when you need transparency or pixel-exact graphics. The quality slider applies to JPEG and WebP.

Resizing always starts from your original file, so you can try different settings without stacking up quality loss. Animated GIFs keep their first frame; PNG transparency is preserved with PNG and WebP output, while JPEG places transparent areas on white.

After resizing you can pick matching colors with the Color Palette Extractor, or check text contrast on the result with the Color Picker.
