Photo and signature requirements vary by receiving organization. Check the current official dimensions, file format, background and size limits before editing. ToolBexa helps prepare a file, but an attractive preview is not evidence that a photograph or signature will be accepted.

Use Signature Resizer & Transparent PNG on ToolBexa as one step in your workflow, then inspect the exported result before uploading or sharing it. If a receiving website gives a format, dimension or input rule, use that requirement rather than a convenient default.
