Image Optimizer

Compress JPEG, PNG and WebP images locally in your browser.

How to optimize images online

1. Upload an image. Choose a JPG, PNG, or WebP file from your device.

2. Select an output format. Use WebP for many web images, JPG for photos, or PNG when lossless output is needed.

3. Adjust the settings. Set the quality for JPG or WebP and optionally enter a maximum width.

4. Optimize and download. Process your image, preview the result, and download the output file.

Choosing the best format and quality

WebP: A useful default for many website images, with adjustable compression.

JPEG: Widely supported and well suited to photographs, but does not preserve transparency.

PNG: Useful when lossless image output or transparency is important, though files can be larger.

Quality and dimensions: Try an 80% quality setting for WebP or JPEG and reduce maximum width only when you do not need the original resolution. Always check the final result visually.

Frequently asked questions

Answers to common questions about compressing images, file formats, quality, and resizing.

An image optimizer can reduce image file size by adjusting compression, changing file format, or resizing dimensions. The result depends on the original image and your selected settings.
You can upload JPEG, PNG, or WebP images and export to WebP, JPEG, or PNG. PNG is lossless; JPEG and WebP offer adjustable quality settings.
Try 80% quality for JPEG or WebP as a starting point. Lower settings often produce smaller files but may introduce visible artifacts. Preview the result before downloading.
Yes. Leave the optional maximum width field blank to retain the original width and height. Enter a maximum width if you want to reduce the dimensions while keeping the aspect ratio.
Not necessarily. A file that is already compressed may become larger after conversion, especially when switching to PNG. Compare the output file size before using it.
Image optimization is performed in your browser using client-side image processing. Very large images may require substantial device memory.
