  • Very large files are limited by your device’s memory; on a phone, split huge files into smaller parts first.
  • HEIC photos are decoded on your device, which takes a few seconds each on slower phones.

Guide

Sepia and historic photo toning: cyanotype, selenium, platinum and more

The brown tones of old photographs are not just a sign of age. Darkroom workers toned their prints deliberately, with chemicals that changed both color and longevity. This tool recreates several of those historic processes, plus a gentle vintage fade and custom duotones, so a modern photo can carry the mood of another era.

Classic sepia

The “Sepia (classic)” look applies the well-known color matrix used in many editors: every color is pulled toward warm browns while relative brightness stays. It is quick and familiar, good for a nostalgic social post.

Historic toning presets

The toning presets work differently. The photo is first turned into a monochrome image, then its tones from shadow to highlight are mapped onto a color range that matches a real process. Sepia gives warm browns from deep chocolate to cream. Cyanotype, the 1840s blueprint process, produces Prussian blue shadows and pale highlights. Selenium toning gives cool purple-brown blacks with neutral highlights. Platinum prints are soft, warm gray with a matte, delicate feel. Van Dyke brown is a rich, reddish-brown iron-silver process. Gold toning gives cooler, slightly blue-black shadows, prized in 19th-century portraits.

Vintage fade

“Vintage fade” keeps the colors of the photo but lifts the blacks, mutes saturation and warms the tones, like a color print that has spent decades in an album. It suits family photos, travel pictures and anything that should feel like the 1970s.

Custom duotone

Pick three colors for shadows, midtones and highlights, and the image is mapped through them. This produces brand-colored duotones for posters and websites, or your own variant of a historic tone. The default navy, warm gray and cream gives an elegant editorial look.

Strength

Strength blends the toned version with the original. Values of 40 to 70 percent give a subtle tint, often more convincing than a full effect, especially for portraits.

Choosing photos

Toned looks suit portraits, architecture, landscapes with strong shapes and still lifes. Scenes that depend on color contrast, such as a red flower against green leaves, may lose their point; check the result, and add contrast if it looks flat.

Finishing touches

For a convincing antique result, add a vignette and fine grain with the Photo Vignette Effect after toning, and crop to a classic format like 4:5 or square. A border with the Add Border to Image tool imitates a print mount.

A short history of toning

Toning began in the 19th century, partly for looks and partly for permanence. Silver prints fade and tarnish, while toned prints, in which the silver is converted to sulfide, selenide or coated with gold or platinum, last far longer. Cyanotypes used iron salts instead of silver and were cheap enough for architects’ blueprints. Each process left a distinctive color, which is why historic photos come in so many different browns, blues and purples.

Using toned images online

Toned photos stand out in feeds where every image is full color. Use one look consistently for a series, such as a family history page or a travel diary, so the collection feels curated.

For two separate tints in shadows and highlights, use Split Tone Image. To start from neutral black and white, try Grayscale Image. For alternative printing processes that need a negative, see the Digital Negative Maker.

Troubleshooting

The file does not open

Check that it is one of the supported formats above and opens in another app. Damaged files and password-protected PDFs cannot be read until they are repaired or unlocked.

It is slow or stops on a very large file

Everything runs on your device, so speed depends on its memory. Close other tabs, use a computer rather than a phone, or split the file into smaller parts first.

The download did not start

Look for your browser’s download bar or icon. Some browsers ask once before a site may download files; allow it and click the button again.

Frequently asked questions

What is the difference between classic sepia and the sepia toning preset?

Classic sepia applies the widely used color matrix that tints all colors brown. The toning preset first turns the photo into a monochrome image and then maps dark to light tones onto a brown range, closer to a toned darkroom print.

Why are old photos brown in the first place?

Many prints were toned with sepia, which converted silver into silver sulfide. It made prints last far longer and gave them their warm brown color. Untoned prints from the same era were often neutral or have yellowed with age.

What is the difference between the two sepia options?

Classic sepia uses the well-known color matrix and keeps a trace of the original colors. Toned sepia first converts to black and white, then maps grays from dark brown to cream, like a real sepia-toned print.
