Four taps from crooked to straight
PictureFramer finds the outer edge of the artwork — frame included — corrects rotation and perspective in one pass, and keeps a strip of the real wall around it.
Pick a photo
Import any photo of a framed picture or painting — or shoot one right in the app — and choose whether to keep the frame and wall, or crop to just the painting.
Automatic detection
The frame is found for you. Nudge a corner by hand if you like.
Preview & fine-tune
Set how much wall stays around the frame. Drag to recenter. What you see is what you save.
Save
The full-resolution result lands straight back in your photo library.
No photo yet? Shoot it in the app
Standing in front of the painting right now? Tap Take Photo and the capture goes straight into detection — no detour through the photo library.
Tap Take Photo
Right on the start screen, next to Choose Photo.
Frame it with the app's camera
A clean viewfinder and one shutter. Turn the phone sideways for a wide painting — the camera follows, and the shot comes out upright.
Straighten as usual
The capture lands in the editor like any picked photo. The original shot is never saved — only your straightened result is.
Any way you hold it
Portrait or landscape, iPhone or iPad, light or dark — every screen rearranges itself instead of just stretching. Turn a phone sideways and the controls move beside the picture, so a wide painting gets the whole height of the screen.
Landscape on iPhone
Controls slide into a side column; Save is always within reach.
Native on iPad
The same app, sized for the big screen — not a blown-up phone layout.
Light, dark, or system
Pick an appearance in Settings, or let it follow your device.
Frame and wall — or just the painting
Pick a mode the moment you open a photo, and switch any time while you edit. Keep the frame with a strip of wall around it, or crop to just the painting inside the frame. Your choice is remembered for next time.
Choose Painting Only
The start screen and the editor both carry a simple toggle. Painting Only tells PictureFramer to look inside the frame.
Corners find the painting
Detection snaps to the painting's edge inside the frame, and the background-margin control disappears — there's no wall to keep.
Museum glass? Gone.
Skylights, spotlights and exit signs love to reflect off protective glass. Mark the glare, and AI repaints the artwork underneath — touching only the pixels you marked.
Mark the glare
Paint over reflections with your finger — pinch to zoom in for fine work. Or tap Auto-detect for a suggested mask and trim it from there.
Let AI repaint it
Your chosen AI model reconstructs the artwork under the glare. Hold to compare before and after, then accept or try again.
Your key, your choice
Bring your own OpenAI or Google Gemini API key. Stored in the iOS Keychain; used only when you tap Remove.
Everything outside your mask is untouched — not “mostly unchanged”, but pixel-for-pixel identical to the original. The straightening pipeline never needs the internet; reflection removal is the one optional step that does.
Setting up AI — two minutes, once
Reflection removal uses your own AI account, so there's no subscription and no middleman. Grab a key, paste it into the app, done.
- Get an API key from either provider:
- OpenAI — create a key at platform.openai.com/api-keys. Any funded account works.
- Google Gemini — create a key at aistudio.google.com/apikey. Important: the image model needs a paid plan — free-tier keys look valid but every removal fails with a quota error. Enable billing on the key's project first.
- Open Settings in the app (gear icon on the start screen), pick your provider, paste the key, and tap Validate Key.
- That's it. The key is stored in your device's Keychain and used only when you tap Remove. A typical removal costs a few cents, billed by your provider.
Seeing “Rate-limited by the provider … check your plan and billing details” with Gemini? That's the free-tier quota, not actual rate limiting — upgrade the plan or switch to OpenAI.
Made for museum days
Everything you photograph from the side, delivered as if you had stood dead center.
True perspective correction
Rotation, horizontal and vertical keystone fixed in a single transform — not just a crop.
Frame or painting, your call
Keep the frame with a strip of wall around it, or crop to just the painting inside the frame — pick a mode up front, switch any time.
Real background, not padding
The margin around the frame is the actual wall from your photo, at any width you choose.
Full resolution
Previews are instant; the saved image is rendered from your original pixels.
Shoot it in-app
Take the photo with the app's own camera, in portrait or landscape. The capture feeds straight into detection — only the straightened result lands in your library.
iPhone and iPad, any orientation
Every screen adapts to portrait and landscape on both devices, and to light or dark appearance.
Works without a frame
Unframed canvases straighten just as well — anything with a clean rectangular edge.
AI reflection removal
Glare on protective glass? Mark it and let AI rebuild the artwork beneath — only inside your mask, guaranteed.
Private by design
Straightening happens entirely on your device — no accounts, no tracking. The optional reflection remover sends only the marked region to the AI provider you pick, with your own key, only when you tap Remove.
Shadow-proof
Cast shadow pulling the crop off-center? Drag the preview to recenter it.
