01 / REDACT
Keep the story.
Leave out the personal.
Sharing a receipt or a screenshot? Cover names, addresses and other details with a brush or rectangle. Choose mosaic, blur or a solid cover to suit the image.


Sample content only. Always inspect the exported image before sharing. For highly sensitive details, use sufficient solid coverage.
02 / ANNOTATE
A point worth making.
Underline a total, point out a detail, or add a note. The pen, arrows, outlines and text help your image say exactly what you mean. Zoom in for a closer look; undo when you want to try again.

03 / WATERMARK
Your work.
Your finishing touch.
Add text or an image watermark. Repeat it gently across the image, or place one mark exactly where you want it. Adjust size, spacing, angle and opacity.

04 / KEEP CREATING
Pause. Come back.
Make it yours.
On Android, keep editable projects on your device. Come back to your work, or start fresh from the original. When you are ready, save a separate PNG or choose an app to share it with.

A few things to know.
Are my images uploaded for editing?
No. MaskPX edits images on your device without uploading them to an editing server. If you choose to share through another app, that app handles the image under its own privacy practices.
Does a saved project replace my original?
No. Exports create a separate image. Editable projects can retain an original copy and your edits on the device until you delete them. A saved draft and an exported image are different.
Where can I download MaskPX?
Download the Android app on Google Play. The iOS version is in preparation and is not yet available on the App Store.
