OS Watermark Pro

Watermarks and metadata

Free · In‑App Purchases

Prepare photos, PDFs and videos with watermarks, timestamps and metadata controls. Start free with ads or choose Premium without ads. OS Watermark Pro by OS Studio helps you prepare PDFs, photos and videos before sharing. Add a watermark, capture with a date and time, and control compatible metadata. No OS Studio account is required. CREATE AND RESUME Start with an included template on a white background or build your composition. Combine text, logos, signatures and other elements. Adjust fonts, bold, italic, underline, alignment, colours, size, opacity, position, margins and repetition. Move elements over your file and use Undo/Redo. Simple and Advanced modes are available with every plan. Resume saved projects to continue your work. FREE WITH ADS Combine up to 3 elements, process up to 5 files together and keep 5 personal templates. Use available fonts and everyday controls, view metadata and remove compatible private information. There is no daily export quota and the app does not add its own logo. Ads may appear at a cold launch and before file creation, when permitted and available. Unavailable ads do not block processing. PREMIUM AND FAMILY — IN-APP PURCHASES A monthly or annual subscription unlocks Premium features and removes ads: up to 32 composition elements depending on resources, batches up to 30 files, an expanded template library, TTF/OTF font import, supported advanced outlines and styles, detailed editing of compatible metadata and password protection. The template library has technical limits of 256 templates and 32 MiB of total encoded data; large logos can reduce capacity. Family provides the same features for you and up to 5 other members of your Apple Family Sharing group. Files and projects are not shared automatically. Apple shows prices and billing periods before purchase. No free trial. Subscriptions renew automatically unless cancelled in Apple settings. Purchase, restore and manage access in Settings > Subscriptions. TIMESTAMP AND PRIVACY Capture photos or videos with date and time, with optional GPS and address. Choose the time zone and format before capture, then adjust the block’s appearance and position. Video capture is limited to 10 minutes per recording in every plan. Timestamps are not legal certification. Removing metadata does not remove personal information visible in an image or document. Some fields remain read-only depending on the format. SAVE A COPY Export to Files and, for compatible photos and videos, to Photos. Originals remain separate. Original dimensions are retained when the format allows; JPEG or video rendering can change compression, colours or HDR. This is not a lossless guarantee. With Premium, a password protects a PDF copy, converts a photo into a protected PDF, or stores a video in an .imprynta file opened by the app. Passwords cannot be recovered. Media processing stays on the device. Advertising uses Google AdMob and its privacy choices. Optional font downloads contact GitHub without sending media or watermark text. Compatible PDF, JPEG, PNG, HEIC, MP4 and MOV files. French, English, Italian, German and Spanish. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
