Image watermark allows you to select any image as a watermark. Hold the circular slider to adjust the watermark image size, transparency, and tilt angle. You can also check tiled watermark to achieve the effect of multiple tiled image watermarks. You can use the slider to adjust the image watermark tiling density.
ID Photo
Upload a clear front-facing portrait photo, otherwise detection will fail.
The crop box is automatically generated at the optimal size and position based on intelligent face recognition. You can also manually adjust the crop size and pan the crop box position. On the right, you can select various background colors and rich specifications. You can download a single photo or an 8-photo layout, convenient for printing multiple photos at once.
Image Split and Merge
Selecting 1 image defaults to image split mode, selecting multiple images defaults to image merge mode. You can select up to 16 images for merging.
In image merge, besides selecting preset ratios for canvas size, you can also manually input canvas size, maximum 8000x8000px.
In image merge, clicking an image selects it. The selected image will have a blue border around it. After selecting an image, you can use the mouse wheel to zoom in/out, maximum 500% of the original image. Hold the mouse on the image to pan it. Moving the image to an adjacent image position will automatically swap image positions.
After selecting an image, click the flip button at the bottom of the right sidebar to flip the image. Click the reset button to restore to the initial state.
After selecting an image, drag the rotation slider at the bottom of the right sidebar to rotate the image.
Place the mouse at the seam between images and hold the mouse to drag and adjust the seam position.
Canvas background defaults to white. You can select any color as the canvas background, or upload an image as the canvas background. Border size, spacing, and corner radius can all be adjusted with sliders.
Document to Image
Supports PDF document upload. You can choose page-by-page conversion (each page converts to one image) or convert to long image (multiple pages are stitched into one long image). If your document is PPT/Word, please first export it as a PDF document with Office before uploading.
Selecting ultra-high or high quality for image quality, although displaying good quality, will result in larger image size and file size. If you need smaller image size and file size, please select normal or compact mode for better results.
Conversion range can input any page number range. You can flexibly select any continuous segment of page numbers, which helps precise conversion and reduces image size and file size.
When converting to long image, if image length exceeds 16383 pixels, WEBP format cannot be selected. If image length exceeds 65535 pixels, JPG/JPEG format cannot be selected. PNG format has no image length restrictions.
Image to Document
Supports uploading up to 200 images to convert into one document or multiple documents. Supports saving as PDF document.
Hold and drag photos to adjust image page order. After selecting output method and page size, click the convert button below to convert to the corresponding document and download.
