Make a smaller file you can still use
File size alone cannot tell you whether an image is acceptable or readable. These guides explain this tool’s behavior through worked examples and checks. Choose a topic, then compare the built-in samples in the image tool.
Compare JPEG, PNG, WebP and transparency
Choose a format for photos, text screenshots or transparent artwork, then compare with the same sample.
Preserve pixel dimensions and readable text
Use worked examples to understand the maximum edge, aspect ratio and further resizing.
Troubleshooting and how files are handled
Distinguish decode failures, over-target results and larger files, and understand local processing.
