Choose shadow and highlight colors for a JPG or PNG, preview the duotone effect, and save it as PNG, JPG or WebP.
Shadows controls darker tones; Highlights controls lighter tones.
The tool maps the image’s brightness between the two chosen colors. It is a stylized two-color treatment, not selective recoloring of individual objects.
Try a palette, then customize Shadows and Highlights.
The gallery offers Lavender, Ocean, Sunset, Slate, Midnight, Coral, Emerald, Amber, Rose, Indigo, Mint, Sepia, Noir, Cyanotype, Cherry, Saffron, Arctic, Grape, Olive, Copper, Peach, Electric, Berry and Sand. A preset fills both color controls and updates the live preview. Change either color to create a custom combination. Lavender is the initial palette.
Compare the important details before saving the effect.
Two colors that are very close in brightness can hide detail. Keep enough difference between Shadows and Highlights for faces, lettering and important shapes to remain visible.
Select File format before Start, then download the finished result.
The result keeps the source dimensions. PNG or WebP can retain existing transparency; JPG produces an opaque image. The output is a finished image, not a reversible filter layer.
Use common web and phone image formats.
WebP and HEIC can be uploaded alongside the other formats listed for this tool. HEIC uses its first image with orientation applied. Full-resolution HEIC pixels are prepared with temporary server processing when a browser editor needs them.
For a single image result: review a raster result and choose its download format.
These controls are available for a supported single image result, not a ZIP archive. Above the image results, choose a file if needed and open Image options. Original keeps the current file bytes and format until you explicitly choose an export or change an image setting. PNG, JPG and WebP are available, with quality choices for JPG/WebP and the actual encoded file size. Opening the panel or cancelling does not replace your download. For animated PNG, GIF or WebP, first confirm that you want a separate still-image copy; the animated original remains available. PDF, TIFF, SVG, PostScript and DICOM files keep their native download path. Save changes updates the selected image and any existing ZIP archive. Other images in the batch retain their current contents. Multiple image results use one ZIP download. Use the image selector to review or adjust an individual image; image previews do not each add a Download button.
For a single image result: set inches or centimeters and 150 or 300 PPI.
These controls are available for a supported single image result, not a ZIP archive. In Image options, open Print size assistant. Selecting 4 x 6, 5 x 7, 6 x 8, 8 x 10 inches or a custom size enables Apply print size to download. At 300 PPI, 4 x 6 creates 1200 x 1800 pixels and 6 x 8 creates 1800 x 2400 pixels. Fit with margins keeps the whole image on white paper; Fill and crop fills the page using a centered crop. Both preserve proportions. PNG, JPG and WebP exports include print density. Disable the setting to return to the original result dimensions. Resizing does not run AI again or guarantee additional detail.
For a single image result: inspect matching before-and-after views and save a comparison card.
These controls are available for a supported single image result, not a ZIP archive. When an aligned original is available, Image options shows a before-and-after divider, synchronized zoom and pan, Fit, 100%, Hold original and Full screen. Download comparison saves a separate PNG card of the current original/result view. No comparison is invented when the source is unavailable or no longer matches the frame. Blend with original starts at 100% result; lower values mix in the aligned source locally. The immutable result stays available, and this adjustment does not make another AI request.
25 MB maximum per file. One input file per run.
Images must stay within 60 million pixels each. Supported multi-frame processing is limited to 200 source frames; aggregate processing and output-size limits also apply.
Files are processed on the server. Preview preparation may also upload a file when browser decoding is unavailable or a document preview is needed. Server downloads are available to your session for up to two hours.
For an image result, use Continue to below the download results to choose a compatible next step. You can select which images to carry over; the next tool starts with its own settings.
Refreshing an editor or download page returns you to the tool page. Download the result before starting a new workflow. See our Privacy Policy for file handling.
