2. Download them all

Save the edited images. Several images are bundled into one ZIP file.

Everything happens on this device. Your images are never uploaded.

To reliably hide text like names and addresses, use a solid box. Fine mosaic or blur can sometimes be reversed to guess the text.

The format stays the same (HEIC is saved as JPG). Photo details like location (Exif) are not kept.

Good to know before you start

  • To hide names, addresses and other text for sure, use “Solid”. A fine mosaic or light blur can sometimes let people guess the original text.
  • Hidden parts can’t be restored from the saved image. Keep your original too.
  • If you only want to remove location data (Exif) from photos, try “Remove photo location (Exif)”.

How the hiding styles differ

When you save, the pixels in the hidden areas are actually rewritten. Nothing is just layered on top, so whoever opens the saved image can’t peel it back to the original.

A mosaic or blur still keeps a little of the original color, though. With large text or low coarseness, someone may be able to guess what it said. Use “Solid” for text and “Mosaic” or “Blur” for faces and backgrounds.

FAQ

Answers to common questions before you start.

Are my images sent anywhere?

No. Everything happens inside the browser on your device, and your images are never uploaded to a server.

Can someone undo the mosaic or blur later?

No. The pixels in the hidden areas are rewritten in the saved image, so the file can’t be restored. However, a fine mosaic or light blur can let people guess text. For text, use “Solid” or raise the coarseness.

How do I hide names and addresses for sure?

Choose “Solid” and draw the box a little larger than the text. That’s the most reliable. You can change the color from black, too.

How do I hide faces?

Pick “Circle” or “Ellipse” as the shape and hide with “Blur” or “Mosaic” for a natural look. You can also cover faces with emoji from the “Stamps” tab.

Can I move or resize an area after drawing it?

Yes. Drag an area to move it, use the bottom-right handle to resize and the top handle to rotate. Select an area to change its style or color, or remove it with the × at its top right. Undo and Redo are there too.

Can I paint any shape?

Choose “Brush” as the shape to hide exactly where you trace. You can also set the brush size with a number.

Can I zoom in to hide small details?

Yes. Use the + and − buttons. On a computer, hold ⌘ or Ctrl and scroll to zoom where the pointer is. On a phone, spread two fingers.

Can I process several images at once?

Yes. Pick as many as you like and choose what to hide on each one. When saving, you can download them all as a ZIP file.

What format are the saved images?

The same format as the original (JPEG, PNG or WebP). iPhone HEIC photos are saved as JPG. Location and other info (Exif) is not included.

Is it free?

Yes. No sign-up and no ads.
