FrameSwift 1.2.1 Preview — X.com sharing

Free Windows photo viewer by Prosper Technologies.

New

• X.com destination button in the guided sharing workspace, alongside Instagram, Facebook, Bluesky, Mastodon, Discord, and Telegram.
• Save photo & open X: saves a prepared JPEG and opens X's composer with the caption prefilled. Attach the saved photo, check the audience, and publish on X. The link does not attach/upload the photo or automatically post.
• Prepared X API v2 adapter: verify user identity, upload JPEG, wait for media readiness, submit image descriptions, create a photo post, and return its link. Credentials stay in memory; uncertain final publication is not automatically repeated.
• X caption counter/preflight uses 280 UTF-16 text units. X's own Unicode/URL weighting may still reject some drafts.
• The final review now allows scrolling through the complete caption.
• Included X setup guide.txt documents developer testing and remaining public sign-in work.

Setup status

Public X sign-in is not configured. Developer testing needs your own authorized X app and a user-context OAuth 2.0 token with the required permissions. X controls endpoint access, credits, rate limits, and any API charges. FrameSwift does not buy access or include an API allowance. Live X posting has not been tested.

Instagram/Facebook integrations retain their existing setup requirements. This release does not provide public Meta sign-in. See the included guides for account support and setup.

Download

Install FrameSwift-1.2.1-Setup-x64.exe below. Requires x64 Windows 10 version 2004 or later, or Windows 11. Close FrameSwift before upgrading. The app/runtime package is self-contained; a signed Microsoft Visual C++ prerequisite is included when needed.

This is an unsigned preview. Review release details and the matching SHA-256 file before installing. Native image viewing, nondestructive editing, Auto Adjust, saved preferences/recovery, and the default-viewer prompt remain included.

Validation

Offline X tests cover exact media bytes, caption/description fields, receipt links, duplicate suppression, processing readiness/failure, metadata errors, secret-safe service errors, caption preflight, and browser URL encoding. Native app checks cover the X tile/setup state plus viewer/edit/export/recovery behavior. Installer checks cover installation, installed app launch, reinstall, removal, and preservation of personal files.

Live social publishing, all codecs/hardware, and every Windows version still need broader acceptance testing. Single JPEG X posts only; no threads, video, scheduling, multiple images, or Premium long posts. Copyright 2026 Prosper Technologies. Free to use; all rights reserved.
