Your image stays in this browser tab. Some browsers keep their navigation bars visible.
How to use
- Choose a PNG, JPEG, WebP, GIF, AVIF or BMP image up to 12 MB. The browser must support its format.
- Drag the picture into place. Use the controls to change its size, rotation, opacity or mirror direction.
- Enable the grid to align your reference. Lock the workspace when positioned to prevent accidental dragging or edits.
- Use fullscreen for a larger area. Reset the view to fit the image again, or remove it to clear the workspace.
What to keep in mind
Images stay in this page's browser memory and are not uploaded by this tool. Reloading clears the image. Images are limited to 8,192 pixels per side and 24 million pixels in total. This is a visual lightbox, not a calibrated physical ruler; zoom and display scaling affect size. Place any tracing material gently without pressing on the display.
Questions
Is my picture sent to a server?
This tool opens a browser object URL for your selected local file. It does not send the image or save it to an account. Remove the image or close the page to release it.
What does locking do?
It prevents dragging and changes to image controls. You can still unlock, reset, remove the image or exit fullscreen. Resizing the window can change the fitted display size.
Can I print the image at an exact size?
This page does not provide a physical-size or print calibration. Its zoom is relative to the image's fit in the current working area, not a measured number of centimetres.
