Reducing image file size is essential for web performance, email attachments, and storage management. There are three main approaches: compression (reducing quality), resizing (reducing dimensions), and format conversion (switching to a more efficient format).
The most effective approach combines all three. Start by resizing to the actual needed dimensions (this often provides the biggest reduction). Then compress with an appropriate quality setting. Finally, convert to the most efficient format for your use case.
With ImgTools, you can perform all three steps. Upload your image, resize to needed dimensions, and download in your preferred format with quality adjustment.
For a quick 80% file size reduction: resize to 1200px wide (if the source is larger), convert to JPEG at 80% quality. For web optimization, convert to WebP for an additional 25-35% savings.
