Compression is a balance
Image compression reduces file size by simplifying image data. The goal is not always the smallest possible file; it is the smallest file that still looks good for its purpose.
A product photo, portfolio image, document scan, and social thumbnail all have different quality needs. Previewing the result matters more than chasing a single perfect percentage.
Use a moderate quality setting first
Open Image Compressor, upload your image, and start with a middle-to-high quality setting. Photos often tolerate compression well, while screenshots, logos, and text-heavy graphics may need a higher setting.
Compare the original and compressed previews before downloading. Look closely at text edges, faces, gradients, and product details because these are where compression artifacts are easiest to notice.
Resize before compressing when dimensions are too large
If a 4000-pixel-wide image will only appear as a 900-pixel blog image, resize it first. Fewer pixels usually means a smaller file before compression even begins.
Use Image Resizer to set realistic dimensions, then use Image Compressor or WebP Converter for the final output. This two-step workflow is often better than heavy compression on an oversized source image.
Choose the right output format
JPG is usually good for photos, PNG is useful for sharp graphics or transparency, and WebP is often a strong choice for modern websites. The best format depends on the image and where it will be used.
Always keep a copy of the original image. Use the compressed version for upload, email, or publishing, and keep the source file in case you need a different size or format later.
