Markepi. Watermark. Sign. Share. Markepi adds beautiful watermarks to your photos and videos, then shares them anywhere without ever cluttering your camera roll. For photos, it can also embed C2PA Content Credentials so viewers can check whether an image has been changed since you signed it. WHY YOU'LL LOVE MARKEPI - Share without auto-saving. Watermark and share in one tap. Markepi never writes to your photo library unless you choose Save, so your camera roll stays clean. - Photos and videos. One simple workflow for both. - HDR and metadata preserved. Exports keep their HDR, color profiles, and metadata like GPS, date, and device. You can also strip the fields you would rather not share. - Gallery frames. Choose Classic for a clean centred caption, or Gallery for a matted, two-column layout with an automatic brand mark like "Shot on iPhone 17 Pro" pulled from your photo's own metadata, 25 brands recognized, including the top phone and camera makers. Frame width and sizing are set in real millimetres, and the brand mark can be turned off anytime. - Import from anywhere. Pick media in-app, or send it from Photos, Safari, or any app via the share sheet. - Batch processing. Watermark and sign a whole shoot at once for consistent branding. - Custom templates. Save your favorite watermark and signing setups and apply them with one tap. - Precise placement. Drag text, logos, and your signature anywhere on the photo with your finger. - On-device and offline. All processing happens locally. No accounts, no servers, no network calls. CONTENT CREDENTIALS FOR PHOTOS Markepi can embed C2PA Content Credentials into your photo exports. These are a signed record based on the open standard from the Coalition for Content Provenance and Authenticity. Anyone can inspect them with free tools like contentcredentials.org/verify, and if the photo changes after signing, verification shows it. Content Credentials are currently supported for photos. They stay attached as long as the file is transferred byte-for-byte, such as saving to Files or sharing over AirDrop. Some services and social platforms re-encode images on upload, which can strip the credentials. Signing happens entirely on your device, using an identity stored on your device and hardware-backed by the Secure Enclave where available. Because that identity is device-generated, verifiers show it as a self-declared signer. That means honest provenance, not a claim we cannot back. Existing credentials on your source are preserved rather than overwritten. Video signing is on the roadmap. BUILT FOR CREATORS Whether you are protecting your photography, adding a provenance trail to your work, or just branding your content, Markepi gives you tools that go beyond aesthetics. It is built on open, non-proprietary tooling from the Content Authenticity Initiative. ## Key features - Add watermarks to photos and videos - Embed C2PA Content Credentials for provenance - Share directly without saving to camera roll - Preserve HDR, color profiles, and metadata - Batch processing for multiple files - Customizable watermark templates - On-device and offline processing ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | Markepi Pro Monthly | $0.99 | per month | | Markepi Pro Annual | $2.99 | per year | **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Markepi Pro | $4.99 | one-time | ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/markepi-watermark-and-c2pa/id6782552371/reviews.md ### 5/5 — A developer with good insight. Almost perfect. *2026-09-09* 09 Sep 2026: Developer continues to exceed expectations on new additions and functionality on Markpi of which I believe is the most important to be C2PA on my artwork. The developer also sends out periodic email announcements especially related to App Store reviews. I bumped this to ⭐️⭐️⭐️⭐️⭐️ 11 July 2026: A very responsive developer as shown in his comment below. He already pointed out something I missed so scratch one ‘feature’ off the request list 😊. Others on AppRaven have also gotten interested in the C2PA credentials as well. The developer is interested in the other suggestions as well! I’ll probably nudge this up to five stars when those updates come through. 09 July 2026: I like the fact that this developer has had the design of this app to include a C2PA content credential feature to protect the image from being altered by others without the express permission of the creator. The watermark, logo, and signature work fine; however I would recommend some ‘fine tuning’ on future updates as suggested below. (1) Fixed position logos, signatures, and other watermarks should be free to be moved anyplace in the image the creator would like. I say this because the app itself has no ability to determine the best position of these markings. (2) Logos, signatures and watermarks need to have rotational control in addition to free placement. (3) Borders should have more options besides just white and the thickness control is currently limited. The border control should be in pixels, inches, millimeters as selected by the creator and color control would be a great add to the capabilities. Other that these items, I think that this app is a great addition to the creative world, photographers and artists alike. **Developer response:** Edited 06-09-2026: Great news, this one's done! Logos, signatures, and text watermarks can now be dragged to any spot on the photo with your finger, free-form, not just fixed positions. Border and frame thickness is also improved: it's now set in real millimetres, so it's much finer-grained than before. Color options and full unit selection (px/in) are still on my list. Thanks again for pushing on these. Really appreciate you sticking with the app through the updates! Older Reply: Thank you so much for the thoughtful review and for taking the time to try out C2PA content credentials! Really glad the watermarking, logo, and signature features are working well for you. Quick note: logo rotation is actually already available & you can rotate logos freely alongside placement. Your other suggestions are excellent, and I'll be prioritizing them for upcoming releases: - Free-form positioning for logos, signatures, and watermarks - Expanded border color options and finer-grained thickness control (with unit selection px/in/mm) Thanks again for the detailed, constructive feedback. It genuinely helps shape the roadmap! ### 4/5 — A developer with good insight. Almost perfect. *2026-07-11* 11 July 2026: A very responsive developer as shown in his comment below.
