How to Remove Creases from Old Photos (Safely)
A crease is a break, not a wrinkle. Don't iron the print. Scan it so the fold shows less, then repair the line digitally on a copy.

To remove a crease from an old photo, don't try to iron or press it out. A crease is a break in the paper and the image layer, and flattening at home can make it worse. Scan the print as it is, using a two-pass trick that makes the fold show less, then repair the line on a digital copy. Keep the original print and the untouched scan.
Here's the safe order, and what each step can and can't do.
After you scan the creased print, repair the crease on a copy. Keep the original and the untouched scan.
Why a crease won't iron out
A photographic print is paper with a thin gelatin layer on top that holds the image. When the print is folded, the paper fibers along the line break and the gelatin cracks. That's why the line stays visible after the print is flat again. You're not looking at a wrinkle; you're looking at a scar.
Flattening a photograph is a real treatment, but it's conservator work. The American Institute for Conservation's wiki page on humidification and flattening explains why it's risky: "Humidification alters organic materials by swelling fibers and softening emulsions," and "if the binder layer gets too soft, it can potentially stick to the pressing materials." It also notes that some print types, such as salted paper and platinum prints, "are not suitable for this method." Knowing which kind you have is part of the job.
Even the specialist method has its own risks. Conservator Ana B. Hofmann's 1991 paper on flattening cracks in photographs describes a treatment using "applications of gelatin, moisture and heat," and warns that matte prints can end up with a glossy, "ferrotyped appearance."
What's safe to do with the print
Most of what helps is about not making it worse.
- Don't iron, steam or heat it. Some popular how-tos suggest a steam iron, a pot of boiling water or a pass through a laser printer. All of them apply heat and moisture to the gelatin with no control. Skip them.
- Don't fold it back or force it flat. The Canadian Conservation Institute's care guide for black-and-white prints is blunt: "Do not bend, fold, or roll photographs."
- Don't tape the crease. The Library of Congress photo care page says not to use "self-adhesive tape, sticky notes, glue, or other adhesives on photographs."
- Store it flat. Put it in a sleeve or folder, flat, away from damp. For a rolled or badly curled print, the American Library Association's advice on rolled photos is to store it "until a conservator can flatten them."
- For an irreplaceable print, ask a conservator. The Library of Congress page says "conservation treatment by a photograph conservator may be necessary" and links to the AIC directory of conservators.
If the print is cracked through or split along the fold, it's a tear rather than a crease; how to restore torn photos covers that.
Scan it so the crease shows less
This step makes the biggest difference and almost nobody mentions it.
A flatbed scanner's light comes from one side as it moves across the glass. A crease is a tiny ridge or valley, so it catches that light on one side and throws a shadow on the other. Rotate the print and the light and shadow swap sides.
Photographer and printer Ctein described how to use that in a 2013 column on scanning folds and cracks: "Reversing the direction the scanning light comes from reverses the pattern of shadowing and highlighting in the paper." His method:
- Scan the print at your normal settings. Our guide to scanning old photos covers resolution and handling.
- Rotate the print 180 degrees on the glass and scan it again with the same settings.
- Open both scans in your editor, rotate the second one back, and align them as layers.
- Average them. In Photoshop, that's a stack set to Mean; in any editor, setting the top layer to 50% opacity does the same for two layers.
The crease won't disappear, but the bright edge and dark shadow partly cancel out, leaving a fainter line to repair. Keep both raw scans with the original.
Don't press the lid hard on a brittle print to flatten it for scanning. If it won't lie flat without force, scan it as it lies.
Repair the line digitally
Work on a copy of the averaged scan, never the original file.
A thin line on plain areas: use a healing brush. Adobe's retouching help explains that the Spot Healing Brush "automatically picks samples from around the part of the document to be retouched," and that healing "matches the texture, lighting, transparency, and shading" of the area around it. Brush along the crease in short strokes, a little wider than the line. In free software, GIMP's Heal tool does the same job: Ctrl-click a clean source area, then paint over the line.
Where the crease crosses a face, an eye or lettering: clone carefully. Healing blends from nearby pixels, which can smear an eyelid or a letter into the background. A clone stamp copies a source area you choose, so you can match the edge of a collar or the line of a jaw. Work in small sections and zoom to 100%.
A print with many folds: try AI restoration. A photo that was folded in four, or kept in a wallet for decades, can have dozens of lines. Healing each one by hand takes an evening. An AI restoration tool rebuilds them in one pass, and it's worth comparing the result with a manual repair on the hardest area.
AI rebuilds, it doesn't recover
Where a crease ran across an eye or a mouth, the detail under it was damaged. Any tool, manual or AI, fills it from what's around it. Compare faces with your untouched scan at full size, and if the person looks different, keep the manual repair there.
Fix creases in 43frames
Open photo restoration, sign in, and upload your averaged scan. It accepts JPEG, PNG and WebP up to 10 MB. Each restoration repairs scratches, creases, tears, dust and fading in one pass and returns a sharper, high-resolution copy, 4800 pixels on the long side. It's set up to keep the people, clothes, background and framing as they are, and to keep a black-and-white or sepia photo that way unless you turn on Add color.
If you like the print's grain, turn on Keep film grain; by default the restoration cleans grain along with the damage.
Restoration costs 8 credits per photo, or 10 with Add color. New accounts get 10 starter credits once, enough to try one photo. Then compare the result with your scan, face by face.

FAQ
Can I iron a creased photo flat? No. Heat and moisture soften the image layer, and it can stick or change sheen. Leave flattening to a conservator.
Will flattening under books remove the crease? It may reduce curl, but the line stays, and pressing a brittle print can crack it further.
How do I scan a creased photo so the fold shows less? Scan, rotate 180 degrees, scan again, then align and average the two scans.
What's the best tool to remove a crease digitally? A healing brush for thin lines on plain areas, a clone stamp across faces and lettering, AI restoration for many folds.
Does AI restoration change faces? It can where a crease crosses a face. Compare with your untouched scan.
