Image privacy

The image is decoded and processed on your device. SolvePilot does not receive or store selected image content. Closing the page ends the working session; downloaded results remain in your downloads folder.

Quality, dimensions and color

PNG is appropriate when transparency or lossless graphics matter. JPG is widely compatible for photographs, while WebP commonly offers smaller web files. Resizing cannot recreate missing detail, and color can vary between displays and applications.

Limitations of browser image editing

Large images can exceed mobile memory. Animated files are treated as a still image. Metadata cleaning uses fresh browser encoding, while forensic removal guarantees and official identity-photo approval remain outside this utility.

Important: Keep the source image and confirm output dimensions, quality, transparency and official submission rules.

Frequently asked questions

Is Image Watermark free?

Yes. It is free, requires no account and does not add a watermark unless you select the watermark tool.

Are my images uploaded?

No. Processing happens inside your browser and selected images are not sent to SolvePilot servers.

Does it work on phones?

Yes, in current mobile browsers. Very large photographs may work faster on a computer with more memory.

Will processing reduce image quality?

Lossless PNG keeps detail, while JPG and WebP quality depends on the chosen compression setting. Always review the result.

What image size is supported?

There is no upload limit, but images below 20 MB and 20 megapixels are recommended for reliable browser processing.
