Changelog

Light mode, Windows-native chrome, and the accent tells you what you're working on.

• FixedImage previews didn't show. A still was being rendered inside a <video> tag, which draws nothing. Stills and sequence frames now render as images — and the app labels the file type so AVIF previews reliably.
• NewA light theme, with a toggle in the top-right. Every colour was re-derived rather than inverted: the bright cyan that reads well on near-black scores 2.2:1 as text on white, so light mode takes darker accents and white ink. All six theme/accent combinations clear WCAG AA.
• NewThe accent tells you what you're working on: blue for images, purple for motion.
• NewWindows-native window controls — minimise, maximise and close, top-right where they belong, instead of macOS traffic lights on the left. The logo now sits centred, with a New button on the left.
• BetterYour job survives navigation. Popping over to Presets and back used to throw away the clip and every variant you were reading. Only New clears it now.

Loops it can find, images it can compare, and batches it can decide.

• NewFind best loop — one click scans the clip and trims it to the longest seamless loop. It matches the frame AND the motion at the seam, because a frame can match perfectly while the subject moves the opposite way, which still jerks.
• NewImages. Drop a PNG or JPEG and compare AVIF / WebP / JPEG / PNG the same way — measured. On a test shot AVIF matched PNG's measured quality at 88% smaller.
• NewBatch. Drop a folder and every file gets the same settings and its own measured decision — then save the whole set to one folder.
• NewImage sequences. Point at any frame of an After Effects render and LoopSmith works out the rest — the AE handoff, without an AE plugin. The frame rate is a control, not a guess.
• BetterRecommendations now rank on measured quality when everything was measurable. A lossless PNG that's 8× bigger for +0.0002 SSIM isn't 'best quality' — it's waste, and the app no longer recommends it.

LoopSmith finds your loop.

• NewFind best loop: one click scans the clip and trims it to the longest seamless loop it can find. It matches both the frame and the motion at the seam — a still frame can match perfectly while the subject is moving the opposite way, which still reads as a jerk.
• NewIt's honest about what it found: 'seamless', 'good seam', 'visible seam' or 'rough seam'. A clip with nothing to loop is told so rather than handed a flattering number.
• NewDon't like the first answer? Cycle through the next-best loops — the tightest seam isn't always the segment you wanted.

The app updates itself now.

• NewThe build version sits in the bottom-left corner. Click it to check for updates, click again to download, and once more to restart into the new build.
• NewA changelog page on the site, and the latest notes right under the download button — so you can see what changed before you install.
• BetterNothing downloads in the background. Updates only happen when you ask for them.

A tighter workspace, and the app opens where you actually work.

• FixedThe app opened on the marketing landing page — inside the app you'd already installed. It now boots straight into the workspace, which also cuts a full page load from every launch.
• FixedPresets had no way back. There's now a real Back button, and Esc returns you to the workspace.
• BetterDensity pass: the comparison grid — the whole point of the app — grew 58%. The settings rail no longer scrolls, and the size panel became a single inline strip instead of a 255px box.
• NewThe build version sits bottom-left. Click it to check for updates and install them in one go.

First release — measured export decisions, not guesses.

• NewAV1 export: typically ~45–60% smaller than VP9 at the same measured quality.
• NewMeasured quality (SSIM) on every variant, scored against the exact frames the encoder saw — so size vs. quality is a real comparison.
• NewTarget file size that's actually honoured. GIF and WebP have no bitrate to turn down, so they shrink by dropping frames and pixels — and the app tells you exactly what it changed.
• NewTrim to a loop with a live in/out preview — the single biggest lever for a small GIF.
• NewTransparency detected in the source and preserved across WebM, WebP and GIF.
