About Image Compressor
Image Compressor helps reduce image file size directly in the browser without sending the file anywhere. Select a JPG, JPEG, PNG or WebP image, adjust the compression quality, and generate a smaller output using canvas. This is useful when preparing images for websites, blogs, forms, email attachments, online listings or pages where lighter files improve loading speed. The before and after preview makes it easier to compare visual quality, while the file summary shows the original and compressed sizes so you can decide whether the result is acceptable. Lower quality values usually create smaller files with more visible compression, while higher values preserve more detail. The tool is intentionally simple and responsive, giving you a fast way to optimize individual images without installing photo software. All processing runs locally in your browser, so Toolexa does not upload, store or inspect your image. Download the compressed file when you are happy with the preview.
