FAQ
A: In Single Image Mode, after stopping adding mode, simply drag the number label with the mouse to adjust its position. The number label will follow the mouse while dragging, and its position will be fixed after you release the mouse.
A: In Continuous numbering mode, the number automatically increases with each click (1, 2, 3...), making it suitable for sequential labeling. In Confirm number each time mode, an input box appears with each click so you can manually enter a number, making it suitable for scenarios that require skipped numbers or custom numbering.
A: Select "Custom position" mode, first click on the first image to mark the number position, then click "Confirm position". The system will apply the number to all images using the same relative position ratio. You can also choose a preset position (top left, top right, etc.) and apply it directly.
A: Adjust the "Fill opacity" slider to a lower value or 0. When the opacity is 0, the inside of the circle is completely transparent, showing only the border and number. This is ideal for use on complex background images, allowing the background content to show through the circle.
A: Yes. Single-image mode saves in PNG format by default, preserving the original resolution and quality. In batch mode, you can choose PNG (lossless), JPEG, or WebP format, and adjust the compression quality for JPEG and WebP. Number markers are drawn directly on the canvas at the original size, so clarity is not reduced.
A: Three methods are available: Sequential numbering increments from the starting number in file order (1,2,3...); Same number uses the same number for all images; Use numeric file name prefix extracts the number at the beginning of the file name as the sequence number (e.g., "01_photo.jpg" uses 1).
A: All common image formats are supported, including JPG, JPEG, PNG, GIF, BMP, WebP, etc. You can choose PNG, JPEG, or WebP as the output format. PNG is recommended for lossless quality.
