Best settings
For photos, JPG usually gives the smallest file size. PNG is better when transparency or sharp graphic edges matter. If both dimensions and KB size are wrong, resize first and then compress. For passport or visa photos, always verify the latest official requirement before submitting.
Supported files and limitations
Supported formats depend on your browser. Common image tools support JPG, PNG and WebP. PDF tools work best with normal, unencrypted PDFs. Very large files may fail on older mobile devices because all processing happens in browser memory.

FAQs
Can I use signature background remover for online forms?
Yes. Use it when the target form accepts the output format and the final file size, dimensions and quality match the form requirement.
Are my files uploaded to your server?
For supported tools, processing happens locally in your browser. Your selected file is not uploaded to our website server for processing.
Will the final file always match the target exactly?
Image and PDF encoding can vary, so the result may be slightly above or below the target. Always check the final size before submitting.
Can I use this on mobile?
Yes, but very large images or PDFs may fail on older phones because browser memory is limited.
Why was my upload still rejected?
The form may also require a specific format, exact pixel size, background color, page count, or official photo rule.
