Edited pages are flattened. Unedited pages keep searchable content and may retain hidden data.
Visual only: the original PDF content remains underneath every cover and can be extracted. Do not use this mode to hide private information.
Blur or cover sensitive areas
Drag to add a circle. Drag inside to move it; drag the edge to resize.
Choose an image or PDF to start covering private details.
Keyboard: select a shape, then use arrows to move and Shift+arrows to resize.
Blur may leave details recognizable. Use a solid cover for secrets. Review the download before sharing; image metadata is removed.
Cover sensitive details before sharing a picture or PDF
Use circles or rectangles to blur or cover details in JPG, PNG, WebP images and PDF pages. Files are processed on your device. Choose the export mode deliberately: a visual PDF overlay leaves original content underneath, while flattened pages replace the original page content with rendered pixels.
Step by step
- Open an image or PDF, choose a circle or rectangle and add regions over the details to hide. Move or resize each region to cover the complete text or face, including its edges. Use the page arrows to inspect every PDF page.
- Choose blur, soft-edge blur or a solid cover. For short text, codes and account numbers, use an opaque solid cover; blur can leave details recognizable. Check the region at normal viewing size before downloading.
- Choose the output format and, for PDF output, select Flatten all pages or Preserve unedited pages according to your needs. Open the downloaded result and inspect all pages; the editor's selection outlines are not part of the export.
Settings and limits
- Input and image output
- Open one JPG, PNG or WebP image up to 25 MiB and 25,000,000 pixels, or one PDF up to 40 MiB and 30 pages. Image output exports the currently displayed page. PDF output contains every page.
- Flatten or preserve
- Flatten all pages renders every page as an image, losing selectable text and interactive content. Preserve unedited pages flattens edited pages and copies untouched pages with their original content. Anything sensitive on an untouched page therefore remains.
- Visual overlay and resolution
- Visual overlay only copies the original PDF and draws regions above it. It does not remove underlying text or images and must not be used as redaction. Rendered PDF pages are capped at 2× scale, 2,500 pixels on the longest side and 5,000,000 pixels.
Worked example
Download privacy-sample.pdf. On page 1, place a solid rectangle over the entire Account: DEMO-1234 line. Leave page 2 untouched, choose PDF output and Preserve unedited pages, then download the result.
Download the example files
Compare with privacy-preserved-example.pdf: page 1 has a solid cover and no selectable original text layer; page 2 still has selectable public text. Check that the account line is fully hidden. Choosing Visual overlay only would leave its underlying text accessible.
Questions and troubleshooting
Is blur equivalent to secure redaction?
No. Blur and soft edges can leave short text or distinctive details recognizable. Prefer a full opaque cover on an edited, flattened page and inspect the exported file. This is a practical visual-cleaning tool, not a certified redaction audit.
Does preserving pages remove all hidden PDF information?
No. Untouched pages retain original page content, and this tool does not provide a document-wide hidden-information audit. Inspect every page and use a dedicated redaction workflow when you need stronger assurance.
Why does a PDF look softer or lose text selection?
Edited or flattened pages are re-rendered within the resolution limits. Vector detail and text layers become pixels. Preserve unedited pages when appropriate, and keep the original separately if its editability matters.
