How to use Compress JPG: step by step
- Open the Compress JPG tool at https://www.mediaextractr.com/tools/compress-jpg. Confirm that your source file type matches the tool description.
- Prepare a copy of the original and choose the relevant input file or text. For multi-file operations, check order and naming before continuing.

Try a small test before processing your full file

Mistakes and limitations to watch for
- Changing DPI metadata alone does not create more pixels.
- A JPG cannot retain transparent regions the same way PNG can.
- Check both the visual result and file size after saving.
- A smaller output may require lower quality, fewer pixels, a different format, or more compression; no fixed reduction is guaranteed.
- Choose an output format based on transparency, animation, compatibility, and whether repeated lossy conversions are acceptable.
