1. Start from the original
Keep a clean source copy. Work on a duplicate so you can revisit the crop, dimensions or format later.

Image optimization is more than compression
File size is influenced by more than a quality slider. Pixel dimensions, image format, transparency, image content and the destination all matter. A very large source may benefit more from resizing than from aggressive compression.
A useful workflow is simple: keep the original, choose practical dimensions, select a suitable format, create an optimized copy and inspect it where it will actually be used.
Privacy-aware browser processing
Supported ImageRW tools are designed to perform their core transformations in your browser. The source image does not need to be uploaded to a remote server for those operations.

A smaller file is useful only when the image remains fit for purpose.

2. Match the display size
If an image will appear at a small size, resize it before applying aggressive compression. Avoid enlarging a small source unless you accept softer detail.
3. Choose a fitting format
Use JPG for many photographs, PNG when crisp lossless graphics or transparency matter, and WebP when your workflow supports it. Check the result rather than assuming one format always wins.
4. Inspect and compare
Check the output at its intended display size. Compare file size, visible detail, transparency and compatibility before publishing.
How ImageRW approaches image tasks
Image processing is not one-size-fits-all. Photographs, screenshots, logos, product images and illustrations respond differently to compression and format conversion.
That is why ImageRW combines practical tools with explanatory content. The goal is to help you complete a task now and understand how to make a better decision the next time.
Original files matter.
Keep a high-quality source and create web-ready derivatives from it. That makes future crops, dimensions and format conversions easier.
