Why re-rendering is useful
A browser canvas decodes the pixels and exports a new image rather than copying the original file structure. The new file does not normally include the original EXIF block.
This approach is simple for JPEG, PNG, and WebP images, but it may change compression and does not preserve every color-management detail.
Keep the original until verification
Create a separate clean copy with a clear file name. Open it and confirm orientation, dimensions, crop, color, and readability before deleting or archiving the original.
For important photos, keep the original in a protected location because metadata and image quality may be useful later.
Inspect the output again
Use a metadata viewer on the downloaded copy. Confirm that GPS coordinates, camera details, author fields, and comments are not readable in the supported report.
A lightweight viewer cannot prove that every proprietary metadata block is absent, so use specialized forensic tools when the risk is high.
Review the destination and visible pixels
Platforms may generate their own thumbnails or retain upload information. Metadata removal does not control platform logs or account information.
Crop or redact faces, addresses, screens, documents, badges, and reflections that reveal private details visually.
Final review checklist
- Original kept until verification
- New copy visually inspected
- Metadata report checked
- Visible private details removed
- Only the clean copy uploaded
