Sometimes, what moves us is not the whole photo, but a very small part of it. OneStamp helps you crop your photos into stamp-shaped images. With a simple frame, a familiar photo can take on a completely different feeling. You may begin to notice details that once went overlooked, and rediscover the emotions, textures, and stories hidden inside the image. Landscapes, plants, everyday objects, or even an unnoticed corner of daily life can all be reframed here and turned into a small stamp of your own. It is more than a simple crop. It is a different way to look at a photo. When you look closer, you may really start to see something different.

Edition Proof captures a carousel before editing and compares the next edition slide by slide. Review copy, order, layout and rendered changes, then export a visual PDF proof. HOW TO USE THE UPGRADE 1. Create or open a project, then return to Projects → Edition Proof. Capture a named checkpoint. 2. Edit the project and capture another checkpoint. Select two saved editions to compare. 3. Read added, removed, moved, copy, layout and rendered changes. Export the PDF proof or JSON proof record. 4. Use the editor’s Export Studio to share PNG slides or a PDF document, or save rendered slides to Photos after granting permission. Design decks with templates, text blocks and brand kits. Storyboard Lab, Launch Readiness, pacing and publish-kit tools remain available. WHAT TO KNOW Up to 20 saved editions, 30 slides per checkpoint and 24 MB in the proof store. Slide identities drive matching. Proofs contain copy, layout details, fingerprints and preview images; they are not editable project backups. Brand changes or later template edits do not change frozen checkpoints. Accessibility and narrative checks are aids, not publication guarantees. iPhone and iPad. No account required.

Verdict
