How to Use Image Compressor
Start by dragging and dropping an image file into the upload area, or click to browse and select one from your device — JPEG, PNG, and WebP files are all supported. Once your image loads, use the quality slider to choose a compression level from 10% to 100%; lower values produce smaller files at the cost of some visual quality, while higher values preserve more detail. You can also set a maximum width and height if you want to resize the image down as part of the compression process, which is especially useful for shrinking large camera photos before uploading them to a website. Choose your desired output format from the selector — JPEG for photos, PNG for images needing transparency, or WebP for the best overall compression on modern browsers. As you adjust these settings, the tool shows a live before/after preview so you can visually compare the original and compressed versions side by side. Below the preview, you'll see the original file size, the new compressed file size, and the percentage saved, giving you clear feedback on the trade-off you're making. When you're happy with the result, click download to save the compressed image directly to your device. The entire compression process happens using the browser's Canvas API — your image is never uploaded to any server, which means it works even with sensitive or private photos.
Why Use Our Image Compressor?
Large, uncompressed images slow down websites, eat up email attachment limits, and take up unnecessary storage space, but most online image compressors require you to upload your file to a third-party server, which raises privacy concerns and can be slow for larger files. Our Image Compressor processes everything locally in your browser using the Canvas API, so your photos never leave your device — a meaningful difference if you're compressing personal photos or confidential business images. The live before/after comparison and clear file-size savings percentage let you find the right balance between quality and size without guessing. Being able to resize dimensions and change format in the same step means you often don't need a separate image editor at all. It's completely free with no file count limits, no watermarks added to your images, and no waiting on an upload progress bar, making it a fast, private alternative to server-based compression tools.
