Compression Toolkit — Complete Guide
This page collects the guides for 5 tools in one place. Pick a tool name from the list and its guide opens beside it, so there is no page to navigate to and no account to create.
How to use it
- Open Compression Toolkit → Image Compressor.
- Choose a JPG, PNG, WebP, GIF, BMP, or TIFF image via upload or drag-and-drop.
- Move the quality slider down until the file size fits your limit (optionally set max width/height for downscaling).
- Download and open the result at full size to check for artifacts.
- If it looks bad, move the slider back up and try again.
Use cases
- Shrinking a screenshot to fit under an upload limit.
