Changelog
1.32 (6 November, 2026)(Read announcement)
✨ New Features
- Mirror Folder Output — Compresto can rebuild your input folder tree inside a new folder, which defaults to the Desktop. Compressed files keep their original names. Files that aren't compressed, don't get smaller, or fail are copied as they are, so the mirror has the same folders and the same number of files. Your source folder is never changed
- Folder Tree View — A new Grid / Tree switch shows your files as a folder tree with a live status for each file: a spinner while it runs, then a check, "Original kept", or a failure mark. Folders show their progress. The tree turns on by itself when you drop folders or a large batch. While a batch runs it follows the current file, and "Jump to current" brings you back if you scroll away. Dropped folders are now compressed one folder at a time
- H.266/VVC Video Encoding (experimental) — A new video codec for smaller files
- New AI Renaming Models — GPT-6 Luna, GPT-6.1 Sol, and GPT-6 Astra are now available. A new "Compare model pricing" table shows each model's token prices and an estimated cost per 1,000 images. Click a row to choose that model
- If compressing doesn't make a file smaller, Compresto now keeps the original instead, in every output mode. A kept original is never moved to the Trash, even with "Remove input file(s)" turned on. Results show "Original kept" instead of a negative size. Format conversions, trims, video to GIF, MP3 export, and audio removal still keep their output
- "Retain creation date" and "Retain modification date" now apply to folders in Mirror folder mode, not just to files. Drop Zone, Folder Monitoring, and Clipboard now keep the modification date as well as the creation date
- AI renaming uses fewer tokens. Requests use each model's lowest reasoning effort, and on Retina Macs images are now sent at 512px instead of 1024px
- Manage License opens compresto.app/manage-license with your license key already filled in
- Drop Zone no longer scans whole folders every time you drag something anywhere on your Mac
- "Preserve color profile" embeds the original ICC color profile again, so wide-gamut WebP and PNG images no longer look washed out
- iPhone videos with spatial (Apple positional) audio no longer fail and leave an empty 0-byte file when converted to MP4
- Clipboard auto-compress now puts the compressed file on the clipboard instead of leaving the original there, and the main window no longer loses its clipboard result if you copy something else during a batch
- Folders dropped on Drop Zone now skip unsupported files instead of stopping at the first one
- Fixed the spelling of the
{resolution}token in the file name format help
1.31.1 (3 October, 2026)
🐞 Bug Fixes
- Video and GIF quality changes now stick when Compresto runs in a language other than English, including in presets and Drop Zone settings
1.31 (30 September, 2026)(Read announcement)
✨ New Features
- EPUB Compression — Compress JPEG, PNG, and WebP images inside an EPUB with Best, High, Balance, or Low quality. Available in the main window, Drop Zone, presets, per-file overrides, and deep links. Opening an EPUB in Finder still uses your reader. Copy-protected books are left unchanged, and books that only encrypt their fonts can still be compressed
- Translations — Compresto is now available in English, German, Spanish, French, Brazilian Portuguese, and Simplified Chinese. Choose a language in Settings or on the welcome screen, then restart to apply it
- JPEG and PNG keep their original print resolution (DPI), so compressed images still place at the same size in layout apps
- Keeping EXIF, IPTC, and XMP now copies that metadata onto the compressed file without recompressing pixels, so quality and resize settings stay intact
- Onboarding copy now says what each step does next, from installing compression tools through the finish screen
- Fixed WebP encoding
- Component installation no longer fails on Macs that cannot relocate temporary download files
1.30.1 (12 September, 2026)

1.30 (31 August, 2026)(Read announcement)
✨ New Features
- Target File Size for Images — Compress JPEGs to an exact file size, the same way you already can with video. This mode saves as JPG, and you'll see a warning if a file can't reach the target
- Custom GIF Dimensions — Resize GIFs and video-to-GIF with an exact percentage or max width, on top of the 25/50/75% presets. Works in the main window, Drop Zone, presets, and per-file overrides
- Native Apple Silicon FFmpeg — Apple Silicon Macs now install the arm64 FFmpeg build, so compression no longer depends on Rosetta
- Lighter idle memory — decoded previews are released when the last window closes, while Compresto stays in the menu bar
- Opaque JPEGs no longer turn white during compression
- Finder Open With no longer opens Settings; files compress in the background with your last-used settings, and more file types are registered
- Switching to another app no longer clears the file list
- Dock icon stays visible when the last window closes
- Video target file size is now remembered across launches
- Reveal in Finder no longer opens a window per output folder (which could hang the Mac); one-click Reveal remains when every output shares a folder
- Pressing Return in text fields no longer starts compression
1.29 (30 June, 2026)(Read announcement)
✨ New Features
- Offline AI Renaming with Ollama — Auto-rename files entirely on-device using a local Ollama model, with vision-based renaming, automatic model discovery, and a config UI in AI renaming settings
- Inline Output Renaming in the Notch — Rename the compressed output file directly from the notch viewer; press Esc to cancel and the notch stays up long enough to finish editing

1.28.1 (4 June, 2026)

- Finder Tags Preserved — Finder tags on source files are now applied to compressed outputs so your tag-based workflows keep working
