Tool guide
Watermark, compress and crop images
Add a text watermark, adjust JPEG compression quality or crop a selected area of one image, then download the result.
How to use
- Choose a local or history image.
- Configure an operation, inspect the result and download.
Example and expected result
Example: import an image → Compression → quality 0.8 → export JPEG.
Compression keeps the original dimensions; inspect the resulting size.Capabilities and limits
- Processes one image at a time, without batch watermarking.
- JPEG compression is lossy and removes transparency; cropping is not proportional resizing.
Troubleshooting
Compare the source format and quality if the output is not smaller. Use a transparency-capable output for transparent backgrounds.
Data processing and storage
Images are processed in the browser and results enter IndexedDB image history. Delete entries in the history panel or clear site data.
