Frequently Asked Questions for Image Optimization
The most effective strategy is to combine formats and resizing. First, convert the image to the **WEBP format** for maximum compression. Second, use the 'Max Width' setting to ensure the image is no larger than necessary (e.g., 1920px). This combination provides the smallest file size possible.
If you save a PNG as a PNG, changing the quality slider does little, as PNG is a lossless format. The best way to **compress PNG files** is to use the 'Convert to WEBP' option. WEBP supports transparency while offering significantly better file size reduction than standard PNG compression.
Yes, absolutely. Our tool is a **secure image compressor** because it is a zero-upload tool. Your image files are processed directly on your computer's CPU and memory and are never transmitted to our servers, ensuring your privacy is maintained throughout the compression process.
If you upload a highly-compressed file (like a tiny logo or an already optimized JPEG) and choose the original format, the size may not decrease. To see a change, try converting to a different format (like JPEG or WEBP) or significantly lowering the quality slider to find the minimum viable size.
