It allows you to pixel-perfectly resize images, apply smart compression to reduce file size by up to 90% without noticeable quality loss, and convert outdated formats like JPG into modern, SEO-friendly WEBP.

Frequently Asked Questions

What is the best format for websites: JPG, PNG, or WEBP? expand_more
For modern websites, WEBP is generally the best choice as it offers superior compression for both photographs and graphics. Use PNG if you need transparency (though WEBP supports it too) and JPG only for photos if WEBP is not an option.
Does compressing an image ruin its quality? expand_more
Not necessarily. Our tool uses "lossy" compression, which intelligently removes image data that the human eye cannot easily perceive. A quality setting of 80% usually results in a much smaller file that looks nearly identical to the original.
What is the ideal image size for a website? expand_more
As a general rule, try to keep full-width banner images under 200KB, and smaller blog photos under 100KB. In terms of dimensions, a width of 1920px is usually sufficient for large desktops, and 1200px for standard content areas.
Why is the quality slider disabled for PNG? expand_more
PNG is a "lossless" format. It doesn't use the same type of compression quality settings as JPG or WEBP. To reduce PNG size, you typically need to reduce the number of colors or dimensions.
Is my data secure? expand_more
Yes. This is a 100% Client-Side tool. Your images are processed in your own browser's memory and are never uploaded to our servers.
Can I resize multiple images at once? expand_more
Currently, we focus on single-image precision to allow for individual cropping and quality adjustments. Batch processing may be added in a future update.
What happens if I convert a transparent PNG to JPG? expand_more
JPG does not support transparency. If you convert a transparent PNG to JPG, the transparent areas will be filled with solid white. If you need to maintain transparency, convert to WEBP instead.
Is this tool free? expand_more
Yes, it is completely free for unlimited use for both personal and commercial projects.
